CDF1 — Brassica juncea

Summary

BjCDF1 (BJUB04G52210S) on chromosome B04 of Indian mustard encodes a Dof zinc-finger protein with DNA-binding transcription repressor activity and RNA polymerase II cis-regulatory region sequence-specific DNA binding. It is associated with regulation of circadian rhythm, upregulation of long-day photoperiodism and flower development, regulation of timing of transition from vegetative to reproductive phase, temperature compensation of the circadian clock, response to blue and far red light, response to cold and hydrogen peroxide, and negative regulation of cellulose anabolism. The gene has been linked to numerous agronomic traits including flowering time, photoperiod sensitivity, plant height, seed growth and development, drought tolerance, disease tolerance, herbicide sensitivity, and salt tolerance. It is also associated with chloroplast organization, starch grain synthesis, leaf senescence, and transpiration rate. Studies of related genes in other species link the family to photoperiodic flowering time control, drought escape, and salt tolerance.
