Characterization of seed storage proteins in Populus and their homology with Populus vegetative storage proteins.
We investigated the synthesis and accumulation of vegetative storage proteins (VSPs) in poplar plantlets and the homology between poplar seed storage proteins (SSPs) and VSPs. One-dimensional SDS polyacrylamide gel electrophoresis confirmed that both seed and vegetative storage proteins contained two predominant polypeptides of MW 32 and 36 kDa, but the subunit composition of the polypeptides d...
متن کاملNovel Regulation of Vegetative Storage Protein Genes.
Until recently, storage protein research has been largely restricted to the seed-specific reserve proteins, which provide nutrients to seedlings during their early growth. Their abundance, and the potential for improving seed nutritional quality, were early incentives to investigate seed storage proteins, and they continue to be intensively studied as a plant model for tissue-specific and devel...

متن کاملFLOWERING LOCUS T duplication coordinates reproductive and vegetative growth in perennial poplar.
Annual plants grow vegetatively at early developmental stages and then transition to the reproductive stage, followed by senescence in the same year. In contrast, after successive years of vegetative growth at early ages, woody perennial shoot meristems begin repeated transitions between vegetative and reproductive growth at sexual maturity. However, it is unknown how these repeated transitions...
متن کاملPhotoperiod control of poplar bark storage protein accumulation.
Bark storage proteins (BSPs) accumulate in the inner bark parenchyma of many woody plants during autumn and winter. We investigated the effect of a short-day (SD) photoperiod on the accumulation of the 32-kilodalton bark storage protein of poplar (Populus deltoides Bart. ex Marsh.) under controlled environmental and natural growing conditions. Sodium dodecyl sulfate-polyacrylamide gel electroph...
