JAZ1 — Brassica oleracea

Summary

BoJAZ1 (BOLC102_C05P040110.1_BOLC102_V1) on cabbage chromosome 5 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, regulation of systemic acquired resistance, downregulation of innate immune response, and regulation of ascorbate and abscisic acid biosynthesis. The gene is linked to numerous agronomic traits including anther length, petal length, seed protein content, seed set percent, leaf trichome density, branch angle, stem length, iron concentration, sulfur and potassium sensitivity, phosphorus response, temperature stress response, aluminum response, and plant male sterility. It localizes to the nucleus, cytoplasm, and chloroplast envelope. Studies of related genes in other species connect the JAZ1 family to stamen development, defense against necrotrophic pathogens, cold tolerance, and jasmonate perception.
