植物通过感知和整合内源和外源信号来精确地控制防御反应。作为一个重要的环境线索,光据报道在植物防御坏死性病原体中起着至关重要的作用。光敏色素相互作用因子(Phytochrome-interacting factor,PIF)是一种重要的转录因子,在光感受器介导的光反应中起重要作用。在这项研究中,我们揭示了PIFs负调控植物对灰葡萄孢的防御。基因表达分析表明,一个子集的防御反应基因的表达水平是较高的pifq(pif 1/3/4/5)突变体比野生型对照,但较低的PIF过表达植物。染色质免疫沉淀试验证明,PIF 4/5直接结合到乙烯反应因子1(ERF 1)启动子。此外,遗传分析表明,ERF 1的过表达显着拯救PIF 4-HA和PIF 5-GFP转基因植物的易感性,PIF控制对B的抗性。Col 1-和EIN 2-依赖的方式。我们的结果提供了令人信服的证据,表明PIF与茉莉酸/乙烯途径一起对于植物对B的抗性很重要。灰绿色
Endogenous and exogenous signals are perceived and integrated by plants to precisely control defense responses. As a crucial environmental cue, light reportedly plays vital roles in plant defenses against necrotrophic pathogens. Phytochrome-interacting factor (PIF) is one of the important transcription factors which plays essential roles in photoreceptor-mediated light response. In this study, we revealed that PIFs negatively regulate plant defenses against Botrytis cinerea. Gene expression analyses showed that the expression level of a subset of defense-response genes was higher in pifq (pif1/3/4/5) mutants than in the wild-type control, but was lower in PIF-overexpressing plants. Chromatin immunoprecipitation assays proved that PIF4/5 binds directly to the ETHYLENE RESPONSE FACTOR1 (ERF1) promoter. Moreover, genetic analyses indicated that the overexpression of ERF1 dramatically rescues the susceptibility of PIF4-HA and PIF5-GFP transgenic plants, and that PIF controls the resistance to B. cinerea in a COI1- and EIN2-dependent manner. Our results provide compelling evidence that PIF, together with the jasmonate/ethylene pathway, is important for plant resistance to B. cinerea.
