Known effects of biopores on root growth, i.e., increased root length and depth were reproduced. Despite reducing root–soil contact, biopores led to increased water uptake in dry periods. Biopores had a larger impact on water uptake for more compact and less conductive soils. Roots are known to use biopores as preferential growth pathways to overcome hard soil layers and access subsoil water resources. This study evaluates root–biopore interactions at the root-system scale under different soil physical and environmental conditions using a mechanistic simulation model and extensive experimental field data. In a field experiment, spring wheat (Triticum aestivum L.) was grown on silt loam with a large biopore density. X-ray computed tomography scans of soil columns from the field site were used to provide a realistic biopore network as input for the three-dimensional numerical R-SWMS model, which was then applied to simulate root architecture as well as water flow in the root–biopore–soil continuum. The model was calibrated against observed root length densities in both the bulk soil and biopores by optimizing root growth model input parameters. By implementing known interactions between root growth and soil penetration resistance into our model, we could simulate root systems whose response to biopores in the soil corresponded well to experimental observations described in the literature, such as increased total root length and increased rooting depth. For all considered soil physical (soil texture and bulk density) and environmental conditions (years of varying dryness), we found biopores to substantially mitigate transpiration deficits in times of drought by allowing roots to take up water from wetter and deeper soil layers. This was even the case when assuming reduced root water uptake in biopores due to limited root–soil contact. The beneficial impact of biopores on root water uptake was larger for more compact and less conductive soils.", "publicationTitle": "Vadose Zone Journal", "publisher": "", "place": "", "date": "2019", "volume": "18", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "180196", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.2136/vzj2018.11.0196", "citationKey": "", "url": "https://onlinelibrary.wiley.com/doi/abs/10.2136/vzj2018.11.0196", "accessDate": "2022-06-09T09:36:39Z", "PMID": "", "PMCID": "", "ISSN": "1539-1663", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "Wiley Online Library", "callNumber": "", "rights": "", "extra": "_eprint: https://onlinelibrary.wiley.com/doi/pdf/10.2136/vzj2018.11.0196", "tags": [], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2022-06-09T09:36:39Z", "dateModified": "2022-06-09T09:36:39Z" } }, { "key": "VNMTEFX9", "version": 313, "library": { "type": "group", "id": 263264, "name": "R-SWMS", "links": { "alternate": { "href": "https://www.zotero.org/groups/r-swms", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/263264/items/VNMTEFX9", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/r-swms/items/VNMTEFX9", "type": "text/html" } }, "meta": { "createdByUser": { "id": 935445, "username": "mjavaux", "name": "Mathieu Javaux", "links": { "alternate": { "href": "https://www.zotero.org/mjavaux", "type": "text/html" } } }, "lastModifiedByUser": { "id": 1431186, "username": "dadelforge", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/dadelforge", "type": "text/html" } } }, "creatorSummary": "Jorda et al.", "parsedDate": "2021", "numChildren": 0 }, "data": { "key": "VNMTEFX9", "version": 313, "itemType": "journalArticle", "title": "Mechanistic modeling of pesticide uptake with a 3D plant architecture model", "creators": [ { "creatorType": "author", "firstName": "Helena", "lastName": "Jorda" }, { "creatorType": "author", "firstName": "Katrin", "lastName": "Huber" }, { "creatorType": "author", "firstName": "Asta", "lastName": "Kunkel" }, { "creatorType": "author", "firstName": "Jan", "lastName": "Vanderborght" }, { "creatorType": "author", "firstName": "Mathieu", "lastName": "Javaux" }, { "creatorType": "author", "firstName": "Christoph", "lastName": "Oberdörster" }, { "creatorType": "author", "firstName": "Klaus", "lastName": "Hammel" }, { "creatorType": "author", "firstName": "Andrea", "lastName": "Schnepf" } ], "abstractNote": "", "publicationTitle": "Environmental Science and Pollution Research", "publisher": "Springer", "place": "", "date": "2021", "volume": "28", "issue": "39", "section": "", "partNumber": "", "partTitle": "", "pages": "55678–55689", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "Google Scholar", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2022-06-09T09:23:31Z", "dateModified": "2022-06-09T09:23:31Z" } }, { "key": "7MKWCX4R", "version": 240, "library": { "type": "group", "id": 263264, "name": "R-SWMS", "links": { "alternate": { "href": "https://www.zotero.org/groups/r-swms", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/263264/items/7MKWCX4R", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/r-swms/items/7MKWCX4R", "type": "text/html" } }, "meta": { "createdByUser": { "id": 935445, "username": "mjavaux", "name": "Mathieu Javaux", "links": { "alternate": { "href": "https://www.zotero.org/mjavaux", "type": "text/html" } } }, "creatorSummary": "Rao et al.", "parsedDate": "2020-08-01", "numChildren": 1 }, "data": { "key": "7MKWCX4R", "version": 240, "itemType": "journalArticle", "title": "Imaging plant responses to water deficit using electrical resistivity tomography", "creators": [ { "creatorType": "author", "firstName": "Sathyanarayan", "lastName": "Rao" }, { "creatorType": "author", "firstName": "Nolwenn", "lastName": "Lesparre" }, { "creatorType": "author", "firstName": "Adrián Flores", "lastName": "Orozco" }, { "creatorType": "author", "firstName": "Florian", "lastName": "Wagner" }, { "creatorType": "author", "firstName": "Mathieu", "lastName": "Javaux" } ], "abstractNote": "Background and aims Monitoring root water uptake dynamics under water deficit (WD) conditions in fields are crucial to assess plant drought tolerance.

Time-lapse photography was used to reconstruct the wheat root morphology network. We used the reconstructed wheat root network without obstacle to calibrate an RSA model implemented in the R-SWMS software. The root network with obstacles allowed calibrating the parameters of a new function that models the influence of rigid obstacles on wheat root growth. Experimental results show that the presence of a rigid obstacle does not affect the growth rate of the wheat root axes, but that it does influence the root trajectory after the main axis has passed the obstacle. The growth recovery time, i.e. the time for the main root axis to recover its geotropism-driven growth, is proportional to the time during which the main axis grows along the obstacle. Qualitative and quantitative comparisons between experimental and numerical results show that the proposed model successfully simulates wheat RSA growth around obstacles.

Osmotic stress is highly dependent on root length density. Sinusoidal potential transpiration leads to larger stress than constant transpiration. Design of efficient water irrigation strategies with a combination of high-quality water and saline water relies on accurate prediction of root water uptake. Macroscopic models are usually used to predict root water uptake at the field scale. However, they miss proper representation of stress processes at the plant scale. A fully mechanistic three-dimensional model was used to investigate the effect of root length density (RLD), transpiration rate and dynamics, potential leaching fraction (LF), and irrigation frequency and salinity on osmotic stress and gradients developed between the soil–root interface and the bulk soil. For the same LF and salinity level of the irrigation water, osmotic stress was larger at lower RLDs and higher transpiration rates. Roots were also more stressed when a sinusoidal transpiration boundary condition was considered. The variability of macroscopic parameters calculated for the simulated data show that macroscopic functions need to take into account RLD and transpiration rate to adequately predict osmotic stress. Finally, small salt concentration gradients were observed in this single-root study where root density was assumed constant with depth. However, future work requires checking salt concentration gradients at the scale of a whole plant, where this assumption does not apply.", "publicationTitle": "Vadose Zone Journal", "publisher": "",

Here, we developed MECHA, a mathematical model that computes the flow of water across the root at the scale of walls, membranes, and plasmodesmata of individual cells, and used it to test hypotheses related to root water transport in maize (Zea mays). The model uses detailed root anatomical descriptions and a minimal set of experimental cell properties, including the conductivity of plasma membranes, cell walls, and plasmodesmata, which yield quantitative and scale-consistent estimations of water pathways and root radial hydraulic conductivity (kr). MECHA revealed that the mainstream hydraulic theories derived independently at the cell and root segment scales are compatible only if osmotic potentials within the apoplastic domains are uniform. The results suggested that the convection-diffusion of apoplastic solutes explained most of the offset between estimated kr in pressure clamp and osmotic experiments, while the contribution of water-filled intercellular spaces was limited. Furthermore, sensitivity analyses quantified the relative impact of cortex and endodermis cell conductivity of plasma membranes on root kr and suggested that only the latter contributed substantially to kr due to the composite nature of water flow across roots. The explicit root hydraulic anatomy framework brings insights into contradictory interpretations of experiments from the literature and suggests experiments to efficiently address questions pertaining to root water relations.

Landsberg and Fowkes presented a solution of the water flow equation inside a root with uniform hydraulic properties. These properties are root radial conductivity and axial conductance, which control, respectively, the radial water flow between the root surface and xylem and the axial flow within the xylem. From the solution for the xylem water potential, functions that describe the radial and axial flow along the root axis were derived. These solutions can also be used to derive root macroscopic parameters that are potential input parameters of hydrological and crop models. In this paper, novel analytical solutions of the water flow equation are developed for roots whose hydraulic properties vary along their axis, which is the case for most plants. We derived solutions for single roots with linear or exponential variations of hydraulic properties with distance to root tip. These solutions were subsequently combined to construct single roots with complex hydraulic property profiles. The analytical solutions allow one to verify numerical solutions and to get a generalization of the hydric behaviour with the main influencing parameters of the solutions. The resulting flow distributions in heterogeneous roots differed from those in uniform roots and simulations led to more regular, less abrupt variations of xylem suction or radial flux along root axes. The model could successfully be applied to maize effective root conductance measurements to derive radial and axial hydraulic properties. We also show that very contrasted root water uptake patterns arise when using either uniform or heterogeneous root hydraulic properties in a soil–root model. The optimal root radius that maximizes water uptake under a carbon cost constraint was also studied. The optimal radius was shown to be highly dependent on the root hydraulic properties and close to observed properties in maize roots. We finally used the obtained functions for evaluating the impact of root maturation versus root growth on water uptake. Very diverse uptake strategies arise from the analysis.

We thus developed a new, more mechanistic model approach for the simulation of root growth in structured soil.MethodsIn our alternative modelling approach, we distinguish between, firstly, the driving force for root growth, which is determined by the orientation of the previous root segment and the influence of gravitropism and, secondly, soil mechanical resistance to root growth. The latter is expressed by its inverse, soil mechanical conductance, and treated similarly to hydraulic conductivity in Darcy’s law. At the presence of macropores, soil mechanical conductance is anisotropic, which leads to a difference between the direction of the driving force and the direction of the root tip movement.ResultsThe model was tested using data from the literature, at pot scale, at macropore scale, and in a series of simulations where sensitivity to gravity and macropore orientation was evaluated.ConclusionsQualitative and quantitative comparisons between simulated and experimentally observed root systems showed good agreement, suggesting that the drawn analogy between soil water flow and root growth is a useful one.", "publicationTitle": "Plant and Soil", "publisher": "", "place": "", "date": "2017/06/01", "volume": "415", "issue": "1-2", "section": "", "partNumber": "", "partTitle": "", "pages": "99-116", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Plant Soil", "DOI": "10.1007/s11104-016-3144-2", "citationKey": "", "url": "https://link.springer.com/article/10.1007/s11104-016-3144-2", "accessDate": "2017-12-19T07:39:43Z", "PMID": "", "PMCID": "", "ISSN": "0032-079X, 1573-5036", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "link.springer.com", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2017-12-19T07:49:33Z", "dateModified": "2017-12-19T07:49:33Z" } }, { "key": "98CLZS7I", "version": 166, "library": { "type": "group", "id": 263264, "name": "R-SWMS", "links": { "alternate": { "href": "https://www.zotero.org/groups/r-swms", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/263264/items/98CLZS7I", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/r-swms/items/98CLZS7I", "type": "text/html" } }, "meta": { "createdByUser": { "id": 935445, "username": "mjavaux", "name": "Mathieu Javaux", "links": { "alternate": { "href": "https://www.zotero.org/mjavaux", "type": "text/html" } } }, "creatorSummary": "Meunier et al.", "parsedDate": "2017", "numChildren": 2 }, "data": { "key": "98CLZS7I", "version": 166, "itemType": "journalArticle", "title": "Towards quantitative root hydraulic phenotyping: novel mathematical functions to calculate plant-scale hydraulic parameters from root system functional and structural traits", "creators": [ { "creatorType": "author", "firstName": "F.", "lastName": "Meunier" }, { "creatorType": "author", "firstName": "V.", "lastName": "Couvreur" }, { "creatorType": "author", "firstName": "X.", "lastName": "Draye" }, { "creatorType": "author", "firstName": "J.", "lastName": "Vanderborght" }, { "creatorType": "author", "firstName": "M.", "lastName": "Javaux" } ], "abstractNote": "Predicting root water uptake and plant transpiration is crucial for managing plant irrigation and developing drought-tolerant root system ideotypes (i.e. ideal root systems). Today, three-dimensional structural functional models exist, which allows solving the water flow equation in the soil and in the root systems under transient conditions and in heterogeneous soils. Yet, these models rely on the full representation of the three-dimensional distribution of the root hydraulic properties, which is not always easy to access. Recently, new models able to represent this complex system without the full knowledge of the plant 3D hydraulic architecture and with a limited number of parameters have been developed. However, the estimation of the macroscopic parameters a priori still requires a numerical model and the knowledge of the full three-dimensional hydraulic architecture. The objective of this study is to provide analytical mathematical models to estimate the values of these parameters as a function of local plant general features, like the distance between laterals, the number of primaries or the ratio of radial to axial root conductances. Such functions would allow one to characterize the behaviour of a root system (as characterized by its macroscopic parameters) directly from averaged plant root traits, thereby opening new possibilities for developing quantitative ideotypes, by linking plant scale parameters to mean functional or structural properties. With its simple form, the proposed model offers the chance to perform sensitivity and optimization analyses as presented in this study. © 2017, The Author(s).", "publicationTitle": "Journal of

understanding and modelling of root water uptake. Despite their importance, there is limited experimental information on how the radial and axial hydraulic conductivities vary along roots growing in soil. Here, a new approach was introduced to estimate inversely the profile of hydraulic conductivities along the roots of transpiring plants growing in soil.\nMethods A three-dimensional model of root water uptake was used to reproduce the measured profile of root water uptake along roots of lupine plant grown in soil. The profile of fluxes was measured using a neutron radiography technique combined with injection of deuterated water as tracer. The aim was to estimate inversely the profiles of the radial and axial hydraulic conductivities along the roots.\nKey Results The profile of hydraulic conductivities along the taproot and the lateral roots of lupines was calculated using three flexible scenarios. For all scenarios, it was found that the radial hydraulic conductivity increases towards the root tips, while the axial conductivity decreases. Additionally, it was found that in soil with uniform water content: (1) lateral roots were the main location of root water uptake; (2) water uptake by laterals decreased towards the root tips due to the dissipation of water potential along the root; and (3) water uptake by the taproot was higher in the distal segments and was negligible in the proximal parts, which had a low radial conductivity.\nConclusions The proposed approach allows the estimation of the root hydraulic properties of plants growing in soil. This information can be used in an advanced model of water uptake to predict the water uptake of different root types or different root architectures under varying soil conditions.", "publicationTitle": "Annals of Botany", "publisher": "", "place": "", "date": "2016-08-18", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "mcw154", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Ann Bot", "DOI": "10.1093/aob/mcw154", "citationKey": "", "url": "http://aob.oxfordjournals.org/content/early/2016/08/17/aob.mcw154", "accessDate": "2016-10-09T09:36:34Z", "PMID": "27539602", "PMCID": "", "ISSN": "0305-7364, 1095-8290", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "aob.oxfordjournals.org", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Axial hydraulic conductivity", "type": 1 }, { "tag": "Root water uptake", "type": 1 }, { "tag": "inverse problem", "type": 1 }, { "tag": "modelling of root water uptake", "type": 1 }, { "tag": "neutron radiography", "type": 1 }, { "tag": "radial hydraulic conductivity", "type": 1 }, { "tag": "root architecture", "type": 1 } ], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2016-10-12T06:47:54Z", "dateModified": "2016-10-12T06:47:54Z" } }, { "key": "H3IWUZCR", "version": 163, "library": { "type": "group", "id": 263264, "name": "R-SWMS", "links": { "alternate": { "href": "https://www.zotero.org/groups/r-swms", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/263264/items/H3IWUZCR", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/r-swms/items/H3IWUZCR", "type": "text/html" } }, "meta": { "createdByUser": { "id": 935445, "username": "mjavaux", "name": "Mathieu Javaux", "links": { "alternate": { "href": "https://www.zotero.org/mjavaux", "type": "text/html" } } }, "creatorSummary": "Schwartz et al.", "parsedDate": "2016-01-01", "numChildren": 1 }, "data": { "key": "H3IWUZCR", "version": 163, "itemType": "journalArticle", "title": "The impact of mucilage on root water uptake—A numerical study", "creators": [ { "creatorType": "author", "firstName": "N.", "lastName": "Schwartz" }, { "creatorType": "author", "firstName": "A.", "lastName": "Carminati" }, { "creatorType": "author", "firstName": "M.", "lastName": "Javaux" } ], "abstractNote": "The flow of water between soil and plants follows the gradient in water potential and depends on the hydraulic properties of the soil and the root. In models for root water uptake (RWU), it is usually assumed that the hydraulic properties near the plant root (i.e., in the rhizosphere) and in the bulk soil are identical. Yet a growing body of evidence has shown that the hydraulic properties of the rhizosphere are affected by root exudates (specifically, mucilage) and markedly differ from those of the bulk soil. In this work, we couple a 3-D detailed description of RWU with a model that accounts for the rhizosphere-specific properties (i.e., rhizosphere hydraulic properties and a nonequilibrium relation between water content and matric head). We show that as the soil dries out (due to water uptake), the higher water holding capacity of the rhizosphere results in a delay of the stress onset. During rewetting, nonequilibrium results in a slower increase of the rhizosphere water content. Furthermore, the inverse relation between water content and relaxation time implies that the drier is the rhizosphere the longer it takes to rewet. Another outcome of nonequilibrium is the small fluctuation of the rhizosphere water content compared to the bulk soil. Overall, our numerical results are in agreement with recent experimental data and provide a tool to further examine the impact of various rhizosphere processes on RWU and water dynamics.", "publicationTitle": "Water Resources Research", "publisher": "", "place": "", "date": "janvier 1, 2016", "volume": "52", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "264-277", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Water Resour.

Methods We used the mechanistic soil-root water flow model R-SWMS to verify this relation. Virtual split root experiments were simulated, comparing horizontal and vertical splits with varying fdry and different strengths of stomatal regulation by chemical and hydraulic signals. Results Transpiration reduction predicted by the direct relations was in good agreement with numerical simulations. For small enough potential transpiration and large enough root hydraulic conductivity and stomatal sensitivity to chemical signalling isohydric plant behaviour originates from H + C control whereas anisohydric behaviour emerges from C control. For C control the relation between transpiration reduction and fdry becomes independent of transpiration rate whereas H + C control results in stronger reduction for higher transpiration rates.

The objective of this study is to revisit this concept and discuss how it may be affected by processes locally influencing root hydraulic properties. A physical limitation to soil water availability in terms of maximal flow rate available to plant leaves (\nQavail) is defined. It is expressed for isohydric plants, in terms of plant-centered variables and properties (the equivalent soil water potential sensed by the plant,\nψs  eq; the root system equivalent conductance,\nKrs; and a threshold leaf water potential,\nψleaf lim). The resulting limitation to plant transpiration is compared to commonly used empirical stress functions. Similarities suggest that the slope of empirical functions might correspond to the ratio of\nKrs to the plant potential transpiration rate. The sensitivity of\nQavail to local changes of root hydraulic conductances in response to soil matric potential is investigated using model simulations. A decrease of radial conductances when the soil dries induces earlier water stress, but allows maintaining higher night plant water potentials and higher\nQavail during the last week of a simulated 1 month drought. In opposition, an increase of radial conductances during soil drying provokes an increase of hydraulic redistribution and\nQavail at short term.

Methods Signalling impacts on the relationship between soil water potential and transpiration were simulated by coupling a 3D model for water flow in soil, into and through roots (Javaux et al. 2008) with a model for xylem transport of chemicals (produced as a function of local root water potential). Stomatal conductance was regulated by simulated leaf water potential (H) and/or foliar chemical signal concentrations (C; H + C). Split-root experiments were simulated by varying transpiration demands and irrigation placement. Results While regulation of stomatal conductance by chemical transport was unstable and oscillatory, simulated transpiration over time and root water uptake from the two soil compartments were similar for both H and H + C regulation. Increased stomatal sensitivity more strongly decreased transpiration, and decreased threshold root water potential (below which a chemical signal is produced) delayed transpiration reduction. Conclusions Although simulations with H + C regulation qualitatively reproduced transpiration of plants exposed to partial rootzone drying (PRD), long-term effects seemed negligible. Moreover, most transpiration responses to PRD could be explained by hydraulic signalling alone.", "publicationTitle": "Plant and Soil", "publisher": "", "place": "", "date": "2014/11/01", "volume": "384", "issue": "1-2", "section": "", "partNumber": "", "partTitle": "", "pages": "93-112", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Plant Soil", "DOI": "10.1007/s11104-014-2188-4", "citationKey": "", "url": "http://link.springer.com/article/10.1007/s11104-014-2188-4", "accessDate": "2014-11-12T16:04:40Z", "PMID": "", "PMCID": "", "ISSN": "0032-079X, 1573-5036", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "link.springer.com", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Ecology", "type": 1 }, { "tag": "Hormonal signalling", "type": 1 }, { "tag": "Partial rootzone drying", "type": 1 }, { "tag": "Plant Physiology", "type": 1 }, { "tag": "Plant Sciences", "type": 1 }, { "tag": "R-SWMS", "type": 1 }, { "tag": "Soil Science & Conservation", "type": 1 }, { "tag": "Soil-root modelling", "type": 1 }, { "tag": "stomatal conductance", "type": 1 } ], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2014-11-12T16:06:30Z", "dateModified": "2014-11-12T16:06:30Z" } }, { "key": "PUBT6W93", "version": 70, "library": { "type": "group", "id": 263264, "name": "R-SWMS", "links": { "alternate": { "href": "https://www.zotero.org/groups/r-swms", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/263264/items/PUBT6W93", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/r-swms/items/PUBT6W93", "type": "text/html" } }, "meta": { "createdByUser": { "id": 935445, "username": "mjavaux", "name": "Mathieu Javaux", "links": { "alternate": { "href": "https://www.zotero.org/mjavaux", "type": "text/html" } } }, "creatorSummary": "Lobet et al.", "parsedDate": "2014-04-01", "numChildren": 1 }, "data": { "key": "PUBT6W93", "version": 70, "itemType": "journalArticle", "title": "Plant Water Uptake in Drying Soils", "creators": [ { "creatorType": "author", "firstName": "G.", "lastName": "Lobet" }, { "creatorType": "author", "firstName": "V.", "lastName": "Couvreur" }, { "creatorType": "author", "firstName": "F.", "lastName": "Meunier" }, { "creatorType": "author", "firstName": "M.", "lastName": "Javaux" }, { "creatorType": "author", "firstName": "X.", "lastName": "Draye" } ], "abstractNote": "", "publicationTitle": "PLANT PHYSIOLOGY", "publisher": "", "place": "", "date": "2014-04-01", "volume": "164", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "1619-1627", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1104/pp.113.233486", "citationKey": "", "url": "http://www.plantphysiol.org/cgi/doi/10.1104/pp.113.233486", "accessDate": "2014-06-19T14:49:40Z", "PMID": "", "PMCID": "", "ISSN": "0032-0889, 1532-2548", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "CrossRef", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "3J999N7V" ], "relations": {}, "dateAdded": "2014-06-19T14:49:55Z", "dateModified": "2014-06-19T14:49:55Z" } } ]
