独脚金内酯（SL）参与植物的生长发育和环境胁迫的适应等多种生物学过程。我们最近报道，SL本质上是诱导气孔关闭的重要调节因子。在这里，我们提出的证据表明，SL对stotamal关闭的影响并不限于拟南芥，因此SL可以作为常见的调节剂在调制气孔的各种植物物种。然而，SL-生物合成抑制剂TIS 108对气孔开度没有影响。此外，SL受体突变体atd 14 -5，类似于SL-缺陷和更多腋生长2（max2）突变体，表现出对干旱胁迫的超敏反应。总之，这些结果加强了SL的作用，作为共同的监管机构在压力恢复能力。
Strigolactones (SLs) have been implicated in many plant biological processes, including growth and development and the acclimation to environmental stress. We recently reported that SLs intrinsically acted as prominent regulators in induction of stomatal closure. Here we present evidence that the effect of SLs on stotamal closure is not limited to Arabidopsis, and thus SLs could serve as common regulators in the modulation of stomatal apertures of various plant species. Nevertheless, TIS108, a SL-biosynthetic inhibitor, exerted no effect on stomatal apertures. In addition, the SL receptor mutant atd14-5, similar to SL-deficient and more axillary growth 2 (max2) mutants, exhibited hypersensitivity to drought stress. Altogether, these results reinforce the role of SLs as common regulators in stress resilience.
