Abstract

In germinating cotton embryos the partial inhibition of RNA synthesis by actinomycin D does not inhibit the incorporation of leucine-(14)C into soluble protein nor cause a loss of polyribosomes during the first 16 hours of germination. This suggests that the protein synthesis observed during this period is directed by messenger RNA which exists in the mature seed and which is not rapidly degraded and resynthesized.

摘要

在萌发的棉花胚中，放线菌素D对RNA合成的部分抑制作用，在萌发的最初16小时内，既不抑制亮氨酸-（14）C掺入可溶性蛋白质，也不会导致多核糖体的丢失。这表明在此期间观察到的蛋白质合成是由成熟种子中存在的信使RNA指导的，且该信使RNA不会迅速降解和重新合成。
