Active DNA demethylation regulates MAMP-triggered immunity in Arabidopsis

Project description:We found that active DNA demethylation is required for MAMP-triggered immunity to bacteria pathogen. Triple mutant plants deficient in ROS1, DML2, and DML3 (RDD) exhibited compromised immune responses such as induction of immune genes .

Principles and characteristics of the WRKY regulatory network of early MAMP-triggered immunity [RNA-Seq]

Project description:During microbe-associated molecular pattern (MAMP)-triggered immunity (MTI) more than 5000 Arabidopsis genes are significantly altered in their expression and the question arises, how such an enormous reprogramming of the transcriptome can be regulated in a safe and robust manner? For the WRKY transcription factors, which are important regulators not only of this defense response, it appears that they act in a complex regulatory sub-network rather than in a linear fashion, which is much more vulnerable to gene function loss either by pathogen-derived effectors or by mutations. In this study we employed RNA-seq, mass spectrometry and ChIP-seq to find evidence for and uncover principles and characteristics of this network.

Arabidopsis CBP60g Contributes to MAMP-Induced SA Accumulation and Is Involved in Disease Resistance

Project description:Salicylic acid (SA)-induced defense responses are important factors during effector triggered immunity and microbe-associated molecular pattern (MAMP)-induced immunity in plants. This article presents evidence that a member of the Arabidopsis CBP60 gene family, CBP60g, contributes to MAMP-triggered SA accumulation. CBP60g is inducible by both pathogen and MAMP treatments. Pseudomonas syringae growth is enhanced in cbp60g mutants. Expression profiles of a cbp60g mutant after MAMP treatment are similar to those of sid2 and pad4, suggesting a defect in SA signaling. Accordingly, cbp60g mutants accumulate less SA when treated with the MAMP flg22 or a P. syringae hrcC strain that activates MAMP signaling. MAMP-induced production of reactive oxygen species and callose deposition are unaffected in cbp60g mutants. CBP60g is a calmodulin-binding protein with a calmodulin-binding domain located near the N-terminus. Calmodulin binding is dependent on Ca2+. Mutations in CBP60g that abolish calmodulin binding prevent complementation of the SA production and bacterial growth defects of cbp60g mutants, indicating that calmodulin binding is essential for the function of CBP60g in defense signaling. These studies show that CBP60g constitutes a calmodulin-dependent link between MAMP recognition and SA accumulation that is important for resistance to P. syringae. This experiment consists of three biological replicates. For each genotype, two leaves per plant were pooled from three pots to prepare total RNA.

MAPK-triggered chromatin reprogramming by histone deacetylase in plant innate immunity

Project description:Microbial-associated molecular patterns (MAMPs) activate several MAP Kinases (MAPKs), which are major regulators of the innate immune response in Arabidopsis that induce large-scale changes in gene expression. Here, we determined whether MAMP-triggered gene expression involves chromatin modifications at the chromosomal level. Our results show that histone acetylation and deacetylation are major regulators of MAMP-triggered gene expression and implicate the histone deacetylase HD2B in the reprogramming of defense gene expression and innate immunity. The MAPK MPK3 directly interacts with and phosphorylates HD2B, thereby regulating the intra-nuclear compartmentalization and function of the histone deacetylase. By studying a number of gene loci that undergo MAMP-dependent activation or repression, our data reveal a mechanistic model for how protein kinase signaling directly impacts chromatin reprogramming in plant defense.
