The hormone abscisic acid regulates development and survival of plants in response to environmental stresses. now demonstrate that in response to stress, abscisic acid can be made available via polymerization of a beta-glucosidase enzyme. This enzyme is reported to hydrolyze glucose-conjugated abscisic acid, thus increasing active abscisic acid concentrations.
激素脱落酸可响应环境胁迫调节植物的发育与存活。现在有研究表明，在胁迫响应过程中，脱落酸可通过一种β-葡萄糖苷酶的聚合作用产生。据报道，这种酶可水解与葡萄糖结合的脱落酸，从而提高活性脱落酸的浓度。
