Abstract

RNA and protein syntheses in axes excised from dry soybean (Glycine max L.) seeds at different levels of deterioration were assayed. Low rates of protein synthesis in slightly deteriorated seeds were not due to losses in ribosomal or soluble fraction activities. However, the lowered rates of RNA and protein syntheses of deteriorated seeds were associated with reduced ATP content of the tissues. Adenine and adenosine conversions to ATP were reduced in deteriorated axes, and these reductions were reflected in reduced incorporation of these compounds into RNA.

摘要

对从不同劣变程度的干大豆(Glycine max L.)种子上切下的胚轴进行了RNA和蛋白质合成分析。轻度劣变种子中蛋白质合成速率较低并非由于核糖体或可溶性部分活性的损失。然而,劣变种子中RNA和蛋白质合成速率的降低与组织中ATP含量的减少有关。劣变胚轴中腺嘌呤和腺苷向ATP的转化减少,这些减少反映在这些化合物掺入RNA的减少上。
