在高等植物形态发生中RNA和蛋白质起着重要作用,可是到目前为止对于胚形成初期RNA和蛋白质合成的知识仍然很少。有关RNA合成的研究主要集中在萌发的胚上。前已报道,在球形胚中出现许多激烈的发育变化,指数生长和双重节律生长开始于球形胚100—200细胞阶段,这些发育的变化反映了RNA和蛋白质代谢方面质和量的变化。本试验测定了水稻和大麦胚形成初期3~H-尿苷和3~H-亮氨酸的掺入情况。
RNA and proteins play an important role in higher plant morphogenesis, but so far there is little knowledge of RNA and protein synthesis at the beginning of embryogenesis. Research on RNA synthesis has focused on germinating embryos. It has been previously reported that many intense developmental changes occur in globular embryos. Exponential and dual rhythmic growth begin at the globular embryo 100-200 cell stage, and these changes in development reflect the qualitative and quantitative changes in RNA and protein metabolism. This experiment measured the incorporation of 3-H-uridine and 3-H-leucine in the embryogenesis of rice and barley.
