叶片衰老是植物固有的生物学过程。已知植物激素水杨酸（SA）和乙烯（ET）可促进衰老。然而，它们在这一过程中的关系尚不清楚。我们发现EIN3和EIL1是ET信号通路中的两个关键转录因子，在sa诱导的拟南芥叶片衰老中是必需的。此外，ET还能增强SA的促衰老作用。生化研究表明，SA信号的主要调控因子NPR1与EIN3相互作用，促进其转录活性。我们的研究表明，SA和ET在衰老过程中协同作用，这与它们在其他生物过程中的拮抗串扰相反。这篇文章受版权保护。版权所有。
Leaf senescence is an intrinsic biological process of plants. The phytohormones salicylic acid (SA) and ethylene (ET) are known to promote senescence. However, their relationship in this process is still unclear. We found that EIN3 and EIL1, two key transcription factors in ET signaling, are required for SA-induced leaf senescence in Arabidopsis. Furthermore, ET enhances the effect of SA in promoting senescence. Biochemical studies revealed that NPR1, the master regulator of SA signaling, interacts with EIN3 to promote its transcriptional activity. Our study suggests that SA and ET function coordinately in senescence, which is in contrast to their antagonistic crosstalk in other biological processes. This article is protected by copyright.
