CDF1 — Brassica juncea

Summary

BJUA02G02120S (BjCDF1) on chromosome A02 of Indian mustard encodes a Dof zinc-finger protein that binds DNA and RNA polymerase II cis-regulatory regions. The gene is associated with regulation of circadian rhythm, temperature compensation of the circadian clock, and upregulation of long-day photoperiodism and flower development. It has been linked to negative regulation of cellulose anabolism, response to cold, hydrogen peroxide, far-red and blue light, and chloroplast organization. Associations with agronomic traits include flowering time, photoperiod sensitivity, plant height, seed growth and development, drought tolerance, disease tolerance, spot blotch, salt tolerance, herbicide sensitivity, and vegetative vigor. The encoded protein localizes to the nucleus, cytosol, and Cajal body. Studies of related genes in other species link the family to photoperiodic flowering time control, drought escape, salt tolerance, and temperature compensation.
