As roots strongly influence carbon allocation and tree development, knowledge of the dynamics of xylem production and maturation in roots at a short time scale is required for a better understanding of the phenomenon of tree growth. This study compared cambial activity and xylem formation in stem and roots in two conifers of the boreal forest in Canada. METHODS: Wood microcores were collected weekly in stem and roots of ten Abies balsamea and ten Picea mariana during the 2004-2006 growing seasons. Cross-sections were cut using a rotary microtome, stained with cresyl violet acetate and observed under visible and polarized light. The number of cells in the cambial zone and in differentiation, plus the number of mature cells, was counted along the developing xylem. KEY RESULTS: Xylem formation lasted from the end of May to the end of September, with no difference between stem and roots in 2004-2005. On the contrary, in 2006 a 1-week earlier beginning of cell differentiation was observed in the stem, with cell wall thickening and lignification in roots ending up to 22 d later than in the stem. Cell production in the stem was concentrated early in the season, in June, while most cell divisions in roots occurred 1 month later. CONCLUSIONS: The intra-annual dynamics of growth observed in stem and roots could be related to the different amount of cells produced by the cambium and the patterns of air and soil temperature occurring in spring.", "publicationTitle": "Annals of Botany", "publisher": "", "place": "", "date": "Nov 2008", "volume": "102", "issue": "5", "section": "", "partNumber": "", "partTitle": "", "pages": "667-674", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Ann.

Seeds were collected from representative berries in term of stage of development. The evolution of seed was followed both macro- and microscopically. For microscopy analysis, seeds were cut, put in a fixation solution, and cut into thin sections with a microtome. Five staining solutions were used for each seed sample: toluidine blue O, phloroglucinol, periodic acid-Schiff's reagent and naphtol blue black, vanillin, and p-dimethylaminocinnamaldehyde. Toluidine blue O staining revealed the evolution of tissue structures during grape seed development. We studied the changes in chemical compounds (lignin, polysaccharides, proteins, and tannins) with the other reagents. Seed lignification was achieved at veraison. Proanthocyanidins were localized in epidermis, inner cells of the soft seed coat, and inner cell layer of the inner integument. Finally, the localization of flavan-3-ols was linked with changes in cell walls of the outer integument.", "publicationTitle": "Journal of Agricultural and Food Chemistry", "publisher": "", "place": "", "date": "Nov 29, 2006", "volume": "54", "issue": "24", "section": "", "partNumber": "", "partTitle": "", "pages": "9206-9215", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J.

We examined how the oviposition behaviour of zoophytophagous Orius insidiosus and the subsequent longevity of its progeny are influenced by the physical structure and internal anatomy of five plant species. Female O. insidiosus oviposit into plant species with the thinnest layers of epidermal and collenchyma cells, a decision that is significantly correlated with the survival of their offspring. Once a plant species is chosen, the female mainly bases her oviposition decisions on epidermal thickness and the surface density of hair-like appendages on the plants. That females laid more eggs and nymphs survived longer on plants with thinner external tissues suggest that the mechanisms that drive female oviposition decisions have evolved such that optimal plant-based resources are available for the females' progeny. Microscopic examination of plant anatomical features revealed that vascular and cellular tissues are fully accessible to the piercing-sucking mouthparts of the developing insects, suggesting that multiple sources of plant nutrients are available to this omnivore. The ecological implications of plant-based contributions to O. insidiosus fitness are discussed.", "publicationTitle": "Animal Behaviour", "publisher": "", "place": "", "date": "April 2008", "volume": "75", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "1495-1502", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1016/j.anbehav.2007.09.029", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/B6W9W-4S03062-1/2/76fc49935dfdea645461d6435245ed73", "accessDate": "2010-04-09T01:25:33Z", "PMID": "", "PMCID": "", "ISSN": "0003-3472", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Orius insidiosus", "type": 1 }, { "tag": "biological control", "type": 1 }, { "tag": "oviposition", "type": 1 }, { "tag": "predator", "type": 1 }, { "tag": "reproductive success", "type": 1 }, { "tag": "trichomes", "type": 1 }, { "tag": "weed", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-04-09T01:25:38Z", "dateModified": "2010-04-09T01:25:38Z" } } ]
