BZIP19 — Oryza sativa Japonica

Summary

OsBZIP19 (also known as BZIP23 or OsbZIP53) on rice chromosome 6 encodes a bZIP transcription factor with DNA-binding, homodimerization, and transcription corepressor activities, as well as NAD ADP-ribosyltransferase activity. The protein localizes to the nucleus and is associated with cellular response to zinc, response to zinc, zinc deficiency response, zinc deficiency tolerance, zinc deficiency adaptation, zinc accumulation, zinc homeostasis, and phosphate accumulation. It is also linked to gibberellic acid homeostasis, lateral root morphogenesis, pollen maturation, and regulation of cell differentiation. Agronomically, OsBZIP19 is associated with grain yield, plant height, anthesis time, chlorophyll content, relative chlorophyll content, drought tolerance, salinity tolerance, disease tolerance, root morphology traits, root development trait, root thickness, root oxidative activity, and responses to oxidative stress, ozone, UV-B light sensitivity, jasmonic acid sensitivity, ethylene sensitivity, and brassinosteroid sensitivity.
