WRKY54

Gene
WRKY54
Protein
Probable WRKY transcription factor 54
Organism
Arabidopsis thaliana
Length
346 amino acids
Function
Transcription factor. Interacts specifically with the W box (5'-(T)TGAC[CT]-3'), a frequently occurring elicitor-responsive cis-acting element (By similarity). Together with WRKY70, negative regulator of developmental senescence, probably via the regulation of several senescence-associated markers genes (PubMed:22268143). Positive regulator of EDS1-dependent defense against E.amylovora (PubMed:22316300). In collaboration with WRKY70, prevents stomatal closure and, consequently, osmotic stress tolerance (PubMed:23815736). Together with WRKY46 and WRKY70, promotes brassinosteroid (BR)-regulated plant growth but prevent drought response by modulating gene expression (PubMed:28576847). Negative regulator of SA biosynthesis (PubMed:28837631). Prevents defense response to the necrotrophic pathogens P.carotovorum and B.cinerea, but promotes defense against biotrophic/hemibiotrophic pathogens P.syringae pv. tomato (Pst) DC3000, probably by regulating negatively the jasmonic acid (JA)/ethylene (ET) and positively the salicylic acid (SA) signaling pathways (PubMed:28837631).
Similarity
Belongs to the WRKY group III family.
