Abstract

Pretreatment of pea (Pisum sativum var. Alaska) sections with any active auxin induces an enzyme which forms aspartate conjugates of exogenously supplied indoleacetic acid, naphthaleneacetic acid, or benzoic acid. Whereas induction of this system is an absolutely auxin-specific process, another enzyme, which forms benzoylmalic acid, is induced both by auxins and by physiologically inactive aromatic carboxylic acids. Induction of both enzymes is abolished by low levels of RNA and protein synthesis inhibitors. The induction specificities and other characteristics of the two systems are compared.

摘要

用任何一种活性生长素预处理豌豆(阿拉斯加豌豆变种)切片,都会诱导一种酶的产生,该酶能对外源供应的吲哚乙酸、萘乙酸或苯甲酸形成天冬氨酸共轭物。虽然该系统的诱导是一个绝对生长素特异性的过程,但另一种能形成苯甲酰苹果酸的酶,既能被生长素诱导,也能被生理上无活性的芳香族羧酸诱导。低水平的RNA和蛋白质合成抑制剂会消除这两种酶的诱导作用。对这两个系统的诱导特异性和其他特性进行了比较。
