Coregulation of soybean vegetative storage protein gene expression by methyl jasmonate and soluble sugars.
The soybean vegetative storage protein genes vspA and vspB are highly expressed in developing leaves, stems, flowers, and pods as compared with roots, seeds, and mature leaves and stems. In this paper, we report that physiological levels of methyl jasmonate (MeJA) and soluble sugars synergistically stimulate accumulation of vsp mRNAs. Treatment of excised mature soybean (Glycine max Merr. cv Wi...
متن کاملMethyl jasmonate treatment eliminates cell-specific expression of vegetative storage protein genes in soybean leaves.
Soybean (Glycine max) plants accumulate a vacuolar glycoprotein in the parenchymal cells of leaves, petioles, stems, seed pods, and germinating cotyledons that acts in temporary nitrogen storage during vegetative growth. In situ immunolocalization of this vegetative storage protein (VSP) revealed that it accumulates in those parenchymal cells in close proximity to existing and developing vascul...
متن کاملExpression of two soybean vegetative storage protein genes during development and in response to water deficit, wounding, and jasmonic acid.
The expression of vspA and vspB genes encoding soybean vegetative storage proteins was studied during seedling development and in response to water deficit, tissue wounding, and jasmonic acid treatment. vspA and vspB encode VSP-alpha and VSP-beta, 28-kilodalton and 31-kilodalton vacuole-localized polypeptides that are 80% homologous. vspA and vspB mRNAs could be distinguished on RNA blots using...
متن کاملNitrogen and methyl jasmonate induction of soybean vegetative storage protein genes.
Vegetative storage protein (VSP) and VSP mRNA levels in soybean (Glycine max) leaves correlated with the amount of NH(4)NO(3) provided to nonnodulated plants. The mRNA level declined as leaves matured, but high levels of N delayed the decline. This is consistent with the proposed role for VSP in the temporary storage of N. Wounding, petiole girdling, and treatment with methyljasmonate (MeJA) in...
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...
