Abstract

Indoleacetic acid at 0.017 millimolar inhibited the formation of three peroxidase isoenzymes in both soluble and wall-bound enzyme fractions of wheat coleoptile (Triticum vulgare) tissue. Hydroxyproline at 1 millimolar prevented the indoleacetic acid-induced inhibition. Indoleacetic acid oxidase activity in the soluble fraction was decreased by indoleacetic acid and was restored by hydroxyproline. Most of the indoleacetic acid oxidase activity was located in the electrophoretic zones occupied by two of the peroxidase isoenzymes influenced by indoleacetic acid and hydroxyproline. At least part of the effect of hydroxyproline on auxin-induced elongation of coleoptile tissue may be through control of auxin levels by indoleacetic acid oxidase.

摘要

0.017 毫摩尔吲哚乙酸抑制了小麦胚芽鞘（Triticum vulgare）组织可溶性和细胞壁结合酶部分中三种过氧化物酶同工酶的形成。1 毫摩尔羟基脯氨酸可防止吲哚乙酸诱导的抑制。吲哚乙酸诱导的可溶性部分吲哚乙酸氧化酶活性降低，并被羟基脯氨酸所恢复。大多数吲哚乙酸氧化酶活性位于受吲哚乙酸和羟基脯氨酸影响的两种过氧化物酶同工酶的电泳区带中。羟基脯氨酸对胚芽鞘组织中生长素诱导伸长的部分作用可能是通过吲哚乙酸氧化酶控制生长素水平来实现的。
