Receptor-like cytoplasmic kinase CDG1 negatively regulates Arabidopsis pattern-triggered immunity and is co-opted by the Pseudomonas syringae effector AvrRpm1

Project description:In this study, we conducted protoplast-based gain-of-function assay to screen 23 members of the RLCK VII family for those whose overexpression can affect flg22-induced MAPK activation. We identified CDG1, a previously characterized positive regulator in brassinosteroid (BR) signaling (Kim et al., 2011), as a new negative regulator of flg22-triggered MAPK activation. We further found that CDG1 could constitutively associate with FLS2 and CERK1, and its transgenic overexpression could significantly reduce the abundances of these two essential PRRs, leading to impaired immune responses to both flg22 and chitin as well as increased susceptibility to bacterial and fungal pathogens. Surprisingly, the CDG1-mediated degradation of FLS2 and CERK1 is independent of E3 ubiquitin ligases PUB12/PUB13, but requires the kinase activity of MEKK1, a MAPKKK positively regulating plant innate immunity (Asai et al., 2002). Moreover, we demonstrated that RIN4 and the P. syringae effector AvrRpm1 could also interact with CDG1, and obtained evidence that CDG1 may be one of the RLCK VII members responsible for the AvrRpm1-induced RIN4 phosphorylation. Our data thus reveal multifaceted moonlight function of CDG1 in Arabidopsis innate immunity in addition to its originally characterized role in BR signaling.

KA120 negatively regulates effector-triggered immunity [RNA-seq]

Project description:Purpose: To understand the autoimmune phenotype in the ka120 mutant and the suppression of ka120 phenotype by the pad4 and ndr1 mutant, we performed the whole genome transcriptome analysis on three-week-old Arabidopsis WT, ka120, ka120 pad4, and ka120 ndr1 plants (the entire rosette was sampled).

Bach2 negatively regulates natural killer cell maturation and effector program

Project description:Bach2 has been reported to regulate multiple immune cell development and function. Here we report that Bach2 is constitutively expressed in relatively immature NK subsets. Bach2 negatively regulates NK cell development and Bach2 deficiency results in NK cell with mature effector phenotype. Thus, Bach2 functions as a negative regulator of NK cell maturation and function.

Translational Regulation of Metabolic Dynamics during Effector-Triggered Immunity

Project description:It is not fully known whether translational regulation also occurs in later stage immune responses, such as effector-triggered immunity (ETI), which often leads to strong metabolic dynamics. In this study, we performed a genome-wide ribosome profiling in Arabidopsis upon ETI activation and discovered that specific groups of genes were translationally regulated, especially metabolic genes in aromatic amino acid, phenylpropanoid, camalexin, and sphingolipid metabolism. The involvement of these components in the induction of ETI was confirmed by genetic analysis, amino acid profiling and exogeneous application of phenylalanine or an inhibitor of aromatic amino acid biosynthesis. Our findings provide new insight into the diverse translational regulation in the plant immune responses and demonstrate that translational coordination of metabolic gene expression is an important strategy for ETI activation.
