JAZ1 — Brassica oleracea

Summary

BoJAZ1 (BOLC102_C08P028660.1_BOLC102_V1) on cabbage chromosome 8 encodes a TIFY/JAZ family protein with core promoter sequence-specific DNA binding, bHLH transcription factor binding, histone deacetylase activity, and transcription corepressor binding activities. It is associated with regulation of defense response to insects, jasmonic acid/ethylene-dependent systemic resistance, downregulation of innate immune response, regulation of systemic acquired resistance, and regulation of abscisic acid anabolism. The gene is linked to numerous agronomic traits including anther length, petal length, seed protein content, seed set percent, leaf trichome density, fruit ripening, sulfur and potassium sensitivity, phosphorus response, iron concentration, aluminum response, temperature stress response, plant male sterility, shoot elongation under submergence, branch angle, stem length, and whole plant size. It localizes to the nucleus, cytosol, chloroplast envelope, and plasmalemma. Studies of related genes in other species connect the JAZ1 family to stamen development, cold tolerance, defense against necrotrophic pathogens, and jasmonate perception.
