The C-terminal region of OsWRKY30 is sufficient to confer enhanced resistance to pathogen and activate the expression of defense-related genes

WRKY proteins are known to play major roles in defense signaling. We identified a pathogen-inducible and SA-inducible OsWRKY30. Our cDNA clone encodes the C-terminal region (CTR) of OsWRKY30. CTR-OsWRKY30 includes the C-terminal WRKY domain and nuclear localization sequence. CTR-OsWRKY30 was suffici...

Description
Summary:WRKY proteins are known to play major roles in defense signaling. We identified a pathogen-inducible and SA-inducible OsWRKY30. Our cDNA clone encodes the C-terminal region (CTR) of OsWRKY30. CTR-OsWRKY30 includes the C-terminal WRKY domain and nuclear localization sequence. CTR-OsWRKY30 was sufficient to bind W-box sequences (TTGACC/T). Overexpression of the CTR-OsWRKY30 resulted in enhanced resistance to pathogens in Arabidopsis and rice. Defense-related genes were constitutively expressed in transgenic Arabidopsis and rice over-expressing CTR-OsWRKY30. Based on promoter transient assays, CTR-OsWRKY30 is sufficient to activate OsPR10a promoter as much as full length OsWRKY30. Taken together, CTR-OsWRKY30 positively regulates defense signaling, thereby resulting in enhanced resistance to pathogens.
