摘要

摘要植物细胞因子是质膜定位受体在调节植物免疫过程中感知的植物肽信号。最近有报道称，富含丝氨酸的植物细胞因子内源性肽12（SCOOP12）被受体激酶雄性发现者1相互作用受体样激酶2（MIK2）识别，并激活拟南芥中的植物免疫反应和对病原体的抗性。在这里，我们发现拟南芥血管野生抗性增强因子1（EWR1）和四个EWR1紧密前肽同源物编码功能性SCOOP肽，这些肽能够通过MIK2和类BRASSINOSTEROID INSENSIVE 1（BRI1）-相关受体激酶1（BAK1）和体细胞胚胎发生受体激酶4（SERK4）激活免疫反应。

EWR1 as a SCOOP peptide activates MIK2-dependent immunity in Arabidopsis

ABSTRACT Phytocytokines are plant peptide signals perceived by plasma membrane-localized receptors in regulating plant immunity. It was recently reported that the phytocytokine SERINE-RICH ENDOGENOUS PEPTIDE12 (SCOOP12) is recognized by the receptor kinase MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2 (MIK2) and activates plant immune responses and resistance to pathogens in Arabidopsis. Here, we show that Arabidopsis ENHANCER OF VASCULAR WILT RESISTANCE 1 (EWR1) and four EWR1 close propeptide homologs encode functional SCOOP peptides, which are able to activate immune responses via MIK2 and BRASSINOSTEROID INSENSITVE 1 (BRI1)-ASSOCIATED RECEPTOR KINASE 1 (BAK1) and SOMATIC EMBRYOGENESIS RECEPTOR KINASE 4 (SERK4).
