AGL18 — Brassica juncea

Summary

BJUB05G23790S (BjAGL18, AGL18) on chromosome B05 of Indian mustard encodes a protein with a K-box domain, possessing sequence-specific DNA binding, transcription regulator activity, and mRNA regulatory element binding translation repressor activity. The gene is associated with negative regulation of seed maturation, floral meristem identity maintenance, floral whorl development, fruit abscission and dehiscence, gibberellin catabolism, downregulation of short-day photoperiodism and flower development, and cellular response to auxin stimulus. It localizes to the nucleus, cytoplasm, and HDAC complex. Associations include flowering time, photoperiod-sensitive flowering, floral organ length and identity, inflorescence development, plant height, leaf morphology and size, seed growth, fruit ripening, water use efficiency, photosynthetic rate, and disease tolerance. Studies of related genes in other species link the family to flowering time, photoperiodic flowering, inflorescence architecture, somatic embryogenesis, and age-related resistance.
