--- _id: '5830' abstract: - lang: eng text: CLE peptides have been implicated in various developmental processes of plants and mediate their responses to environmental stimuli. However, the biological relevance of most CLE genes remains to be functionally characterized. Here, we report that CLE9, which is expressed in stomata, acts as an essential regulator in the induction of stomatal closure. Exogenous application of CLE9 peptides or overexpression of CLE9 effectively led to stomatal closure and enhanced drought tolerance, whereas CLE9 loss-of-function mutants were sensitivity to drought stress. CLE9-induced stomatal closure was impaired in abscisic acid (ABA)-deficient mutants, indicating that ABA is required for CLE9-medaited guard cell signalling. We further deciphered that two guard cell ABA-signalling components, OST1 and SLAC1, were responsible for CLE9-induced stomatal closure. MPK3 and MPK6 were activated by the CLE9 peptide, and CLE9 peptides failed to close stomata in mpk3 and mpk6 mutants. In addition, CLE9 peptides stimulated the induction of hydrogen peroxide (H2O2) and nitric oxide (NO) synthesis associated with stomatal closure, which was abolished in the NADPH oxidase-deficient mutants or nitric reductase mutants, respectively. Collectively, our results reveal a novel ABA-dependent function of CLE9 in the regulation of stomatal apertures, thereby suggesting a potential role of CLE9 in the stress acclimatization of plants. article_processing_charge: No author: - first_name: Luosha full_name: Zhang, Luosha last_name: Zhang - first_name: Xiong full_name: Shi, Xiong last_name: Shi - first_name: Yutao full_name: Zhang, Yutao last_name: Zhang - first_name: Jiajing full_name: Wang, Jiajing last_name: Wang - first_name: Jingwei full_name: Yang, Jingwei last_name: Yang - first_name: Takashi full_name: Ishida, Takashi last_name: Ishida - first_name: Wenqian full_name: Jiang, Wenqian last_name: Jiang - first_name: Xiangyu full_name: Han, Xiangyu last_name: Han - first_name: Jingke full_name: Kang, Jingke last_name: Kang - first_name: Xuening full_name: Wang, Xuening last_name: Wang - first_name: Lixia full_name: Pan, Lixia last_name: Pan - first_name: Shuo full_name: Lv, Shuo last_name: Lv - first_name: Bing full_name: Cao, Bing last_name: Cao - first_name: Yonghong full_name: Zhang, Yonghong last_name: Zhang - first_name: Jinbin full_name: Wu, Jinbin last_name: Wu - first_name: Huibin full_name: Han, Huibin id: 31435098-F248-11E8-B48F-1D18A9856A87 last_name: Han - first_name: Zhubing full_name: Hu, Zhubing last_name: Hu - first_name: Langjun full_name: Cui, Langjun last_name: Cui - first_name: Shinichiro full_name: Sawa, Shinichiro last_name: Sawa - first_name: Junmin full_name: He, Junmin last_name: He - first_name: Guodong full_name: Wang, Guodong last_name: Wang citation: ama: Zhang L, Shi X, Zhang Y, et al.
