植物激素脱落酸（ABA）是控制气孔运动和干旱等胁迫反应的关键信号分子。最近有报道称，ABA 受体的基因操作可以提高植物水分利用效率（WUE）。因此，我们比较了 ABA 受体五重突变体和小麦 ABA 受体过表达拟南芥品系之间 WUE 性状的细节。在受体突变体中，每升水的生物量和种子生产率均降低，但在转基因拟南芥品系中有所提高。这一结果表明，适当调节 ABA 受体可以提高作物的潜在生产力。
The phytohormone abscisic acid (ABA) is a key signal molecule for controlling stomatal movement and stress responses such as drought. Genetic manipulation of ABA receptors has recently been reported to improve plant water use efficiency (WUE). We therefore compared details of WUE traits between the ABA receptorquintuplemutant and wheat ABA receptor-overexpressing Arabidopsis lines. Biomass and seed productivities per liter of water were both reduced in the receptor mutant but improved in the transgenic Arabidopsis lines. This result suggests that appropriate modulation of ABA receptors can extend crop potential productivity.
