The kinetics of development of protein-synthesizing capacity in the imbibing wheat embryo, were studied both in vivo and in vitro. During the first 30 minutes of imbibition protein-synthesizing capacity rises rapidly, lagging about 10 minutes behind water uptake. This rise in synthesizing capacity is accompanied by an increase in polysome content. As imbibition continues, both protein-synthesizing capacity and polysome content increase. With embryos from aged seed, the rate of protein synthesis is initially limited by another, presumably nonribosomal, reaction.
本文研究了吸胀小麦胚中蛋白质合成能力的发展动力学,分别进行了体内和体外研究。在吸胀的最初 30 分钟内,蛋白质合成能力迅速上升,比吸水滞后约 10 分钟。这种合成能力的上升伴随着多核糖体含量的增加。随着吸胀的继续,蛋白质合成能力和多核糖体含量都增加。对于来自老化种子的胚,蛋白质合成的速率最初受到另一种推测是非核糖体反应的限制。
