CDF1 — Brassica juncea

Summary

BjCDF1 (BJUB06G47870S) on chromosome B06 of Indian mustard encodes a Dof-domain protein with DNA-binding transcription repressor activity specific to RNA polymerase II. It is associated with the regulation of circadian rhythm, temperature compensation of the circadian clock, upregulation of long-day photoperiodism and flower development, negative regulation of cellulose anabolism, blue light response, response to hydrogen peroxide, response to far red light, chloroplast organization, transition from vegetative to reproductive phase, regulation of gene expression, ubiquitin-dependent proteolysis, downregulation of transcription, response to cold, and regulation of DNA-templated transcription. The gene is linked to traits including flowering time, photoperiod sensitivity, plant height, seed growth and development, drought tolerance, disease tolerance, spot blotch, salt tolerance, cold stress, oxidative stress, abscisic acid sensitivity, chloroplast development, starch grain synthesis, transpiration rate, leaf senescence, and others. Studies of related genes in other species associate the family with photoperiodic flowering time control, drought escape, and salt tolerance.
