BJUB05G08810S — Brassica juncea

Summary

BJUB05G08810S (BjAP1, also known as BjAGL7) encodes a protein with MADS-box and K-box domains, and is annotated with DNA-binding transcription factor activity, transcription coactivator and corepressor activities, and chromatin binding. In Indian mustard, BjAP1 is associated with floral whorl development, regulation of proanthocyanidin anabolism, abscisic acid breakdown, release of seed from dormancy, and responses to cytokinin and biotic stimuli. The gene is linked to numerous floral and fruit traits including flower morphology, petal number, carpel shape, silique fruit morphology, fruit shattering, seed color, leaf margin serration, secondary shoot axis branch number, and whole plant size. It localizes to the nucleus, cytoplasm, plastid, vacuolar membrane, and plasmodesmata. Studies of related genes in other species connect the family to floral meristem identity, fruit development, pod shatter resistance, seed yield, and temperature-responsive flowering.
