干旱胁迫是对作物生产的一个主要威胁,但目前还没有减轻干旱不利影响的有效方法。在这里,我们报告说,在脱落酸(ABA)受体激动剂AM1的苄基环中加入氟原子,通过增加化合物和受体配体结合口袋中周围氨基酸残基之间的氢键数量来优化其与ABA受体的结合。这种新的化学物质被称为AMFs,在促进气孔关闭和诱导应激反应基因的表达方面具有持久的作用。在拟南芥和大豆植物中应用AMF或受体PYL 2的转基因过表达赋予增加的抗旱性。当AMF被应用于PYL 2过表达转基因植物时,获得了最大的抗旱性增加。我们的研究结果表明,有效的化学物质与ABA受体的转基因过表达的组合是非常有效的,帮助植物对抗干旱胁迫。植物通过植物激素ABA对非生物胁迫做出反应。在这里,Cao等报道了一系列新的ABA受体激动剂,命名为AMF,其具有更高的受体结合亲和力,并且显示当与ABA受体过表达串联使用时,可以显著增加抗旱性
Drought stress is a major threat to crop production, but effective methods to mitigate the adverse effects of drought are not available. Here, we report that adding fluorine atoms in the benzyl ring of the abscisic acid (ABA) receptor agonist AM1 optimizes its binding to ABA receptors by increasing the number of hydrogen bonds between the compound and the surrounding amino acid residues in the receptor ligand-binding pocket. The new chemicals, known as AMFs, have long-lasting effects in promoting stomatal closure and inducing the expression of stress-responsive genes. Application of AMFs or transgenic overexpression of the receptor PYL2 in Arabidopsis and soybean plants confers increased drought resistance. The greatest increase in drought resistance is achieved when AMFs are applied to the PYL2-overexpression transgenic plants. Our results demonstrate that the combining of potent chemicals with transgenic overexpression of an ABA receptor is very effective in helping plants combat drought stress. Plants respond to abiotic stress via the phytohormone ABA. Here, Cao et al. report a series of new ABA receptor agonists, named AMFs, which have higher receptor-binding affinities and show that, when employed in tandem with ABA receptor overexpression, can significantly increase drought resistance
