The effects of sulphur deficiency on the expression of storage-protein genes in developing pea (Pisum sativum) cotyledons were studied. Legumin-gene transcription was decreased by S-deficiency, but not to the same extent as the decrease in the level of legumin mRNA. Vicilin-gene transcription was not significantly affected. Control of gene expression may thus occur during transcription and/or post-transcriptional events.
研究了硫缺乏对发育中的豌豆(Pisum sativum)子叶中贮藏蛋白基因表达的影响。硫缺乏使豆球蛋白基因转录减少,但减少程度与豆球蛋白mRNA水平的降低程度不同。豌豆球蛋白基因转录未受显著影响。因此,基因表达的调控可能发生在转录过程和/或转录后事件中。
