Indol-3-ylacetic acid stimulated stem elongation within 1 h of treatment of Pisum sativum L. cv. Feltham First stem sections. This elongation was accompanied by an increase in the endogenous level of phosphocholine and a decrease in that of CDP-choline. Measurements in vitro of the CDP-base pathway enzymes showed an increase in choline phosphotransferase and a decrease in cytidylyltransferase activity on hormone treatment. These results indicate that the decrease in phosphatidylcholine labelling from [14C]choline that is observed on indol-3-ylacetic acid treatment of pea stem sections is caused by the decrease in cytidylyltransferase activity.
吲哚 - 3 - 乙酸在处理豌豆(Pisum sativum L. cv. Feltham First)茎段1小时内刺激茎伸长。这种伸长伴随着磷酸胆碱内源水平的增加和CDP - 胆碱水平的降低。对CDP - 碱基途径酶的体外测量表明,激素处理后胆碱磷酸转移酶增加,而胞苷酰转移酶活性降低。这些结果表明,在吲哚 - 3 - 乙酸处理豌豆茎段时观察到的[14C]胆碱标记的磷脂酰胆碱减少是由胞苷酰转移酶活性降低引起的。
