TB1 — Brassica juncea

Summary

BJUB07G24990S (TB1, BjBRC1) on chromosome B07 of Indian mustard encodes a TCP transcription factor containing a CYC/TB1_R domain. It has DNA-binding transcription factor activity and is associated with sequence-specific DNA binding, phosphatidylethanolamine binding, and protein binding. The gene is associated with regulation of shoot development, meristem determinacy, secondary shoot formation, shade avoidance, photoperiodism and flowering, flower development, response to strigolactone, specification of symmetry, sporocyte differentiation, and regulation of stomatal movement. It localises to the nucleus and cytoplasm. Associations include traits such as shoot axis branching, axillary bud morphology, seed yield, fruit number, flowering time, leaf morphology, inflorescence length, anther morphology, and temperature stress response. Studies of related genes in other species link the family to axillary bud development, photoperiodic flowering, fruit number, and heat stress memory.
