The metabolism of soluble nucleotides was investigated in wheat (Triticum aestivum var. Olympic) aleurone layers treated with gibberellic acid. Whereas nucleotide levels were relatively unaffected by the treatment, a transient increase was observed in the incorporation of (32)P. The effect was maximal 30 to 60 minutes after gibberellic acid was administered, and by 180 minutes incorporation was lower than in the control. The greatest changes were detected in the nucleoside triphosphates, particularly in cytidine triphosphate. The findings are discussed in relation to the mode of action of gibberellic acid.
研究了赤霉素处理的小麦(Triticum aestivum var. Olympic)糊粉层中可溶性核苷酸的代谢。虽然处理对核苷酸水平的影响相对较小,但(32)P 的掺入量却出现了短暂的增加。这种效应在赤霉素处理后 30 至 60 分钟达到最大值,而 180 分钟时的掺入量低于对照。核苷三磷酸,特别是胞苷三磷酸,发生了最大的变化。这些发现与赤霉素的作用模式有关。
