生长素诱导乙烯产生和脱落酸合成机制：Grossmann模型

Grossmann proposed that at high concentrations, both natural auxins and auxin-like herbicides induce the production of the plant hormone ethylene, thereby triggering the biosynthesis of another plant hormone called abscisic acid (ABA). This model suggests that at high concentrations, auxins increase the enzyme activity of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, which is a key regulatory enzyme in ethylene biosynthesis.
