The chloride channel family gene CLCd negatively regulates pathogen-associated molecular pattern (PAMP)-triggered immunity in Arabidopsis.

ABSTRACT: Chloride channel (CLC) family genes are ubiquitous from prokaryotes to eukaryotes and encode proteins with both channel and transporter activities. The Arabidopsis thaliana genome encodes seven CLC genes, and their products are found in a variety of cellular compartments and have various physiological functions. However, a role for AtCLCs in plant innate immunity has not previously been demonstrated. Here it is reported that AtCLCd is a negative regulator of pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI). T-DNA insertion mutants of AtCLCd exhibited enhanced responses to the elicitor, flg22. The PTI phenotypes of the clcd mutants were rescued by expression of AtCLCd. Overexpression of AtCLCd led to impaired flg22-induced responses. In line with a role for AtCLCd in PT
