生长素诱导乙烯和脱落酸产生：Grossmann模型解释

Grossmann proposed that at high concentrations, both natural auxins and auxin herbicides induce the production of the plant hormone ethylene, thereby triggering the biosynthesis of another plant hormone, 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.
