Cycloheximide inhibited ethylene production in excised pea root tips treated with high levels of indoleacetic acid (100 mum and 10 mum). In contrast, cycloheximide did not inhibit ethylene production induced by a lower concentration (1 mum) of indoleacetic acid unless it was added 2 hours before the indoleacetic acid treatment. These observations suggest that indoleacetic acid has two effects on the enzyme system involved in ethylene synthesis. At low concentrations (1 mum) indoleacetic acid increases ethylene production without protein synthesis, whereas at the higher concentrations, the synthesis of new protein is associated with increased ethylene production.
环己亚胺抑制了用高水平吲哚乙酸(100 毫摩尔和 10 毫摩尔)处理的豌豆根尖的乙烯生成。相反,环己亚胺不会抑制用较低浓度(1 毫摩尔)吲哚乙酸诱导的乙烯生成,除非在吲哚乙酸处理前 2 小时加入环己亚胺。这些观察结果表明,吲哚乙酸对参与乙烯合成的酶系统有两种作用。在低浓度(1 毫摩尔)时,吲哚乙酸增加乙烯生成而不进行蛋白质合成,而在较高浓度时,新蛋白质的合成与乙烯生成的增加有关。
