BJUB06G50080S — Brassica juncea

Summary

BJUB06G50080S (BjABI5) encodes a bZIP transcription factor of the BZIP46-like family, possessing DNA-binding transcription activator activity, protein phosphatase regulator activity, and multiple additional molecular functions including SUMO transferase activity and Ca2+/CaM-dependent kinase activity. In Indian mustard, this gene is associated with regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, and salicylic acid metabolic processes, as well as responses to pH, calcium ions, and salinity. It is linked to numerous traits including seed set percent, endosperm storage protein content, inflorescence length, leaf elongation rate, whole plant size, and sensitivities to alkali, copper, magnesium, manganese, nitrogen, and nitrate. Additional associations include plant male sterility, lignin biosynthesis, phosphorus uptake, cadmium and iron concentrations, and wheat powdery mildew disease response. Studies of related genes in other species connect the family to abscisic acid responsiveness, seed longevity, germination inhibition, salt stress tolerance, and water use efficiency.
