WRKY33 — Arabidopsis thaliana

Summary

AT2G38470 (WRKY33) on chromosome 2 of Arabidopsis thaliana encodes a WRKY DNA-binding domain transcription factor with sequence-specific DNA binding, calmodulin binding, and protein kinase activity. WRKY33 is associated with immunity to Botrytis cinerea, resistance to Alternaria brassicicola, pathogen defense response, phytoalexin biosynthesis, and H2O2 homeostasis. It has been connected to drought stress response, NaCl tolerance, hypocotyl elongation, and root architecture. The gene is linked to jasmonic acid and ethylene-dependent systemic resistance, abscisic acid breakdown, melatonin anabolism, reactive oxygen species-mediated programmed cell death, and cellular thermotolerance. Additional associations include leaf temperature, turgor pressure, cadmium concentration, aluminum response, photosynthetic rate, stomatal closure, flowering time, seed germination, and disease tolerance. Related genes in other species are linked to secondary cell wall formation and cadmium accumulation.
