AP1 (BJUA07G26900S) — Brassica juncea

Summary

BJUA07G26900S (BjAP1, AP1) on Indian mustard chromosome A07 encodes a MADS-box transcription factor containing MADS-box and K-box domains, with annotated activities including DNA-binding transcription factor activity, transcription coactivator and corepressor activity, chromatin binding, and histone binding. The gene is associated with floral whorl development, floral meristem identity, fruit development, and cauline leaf development. It has been linked to numerous traits including flower and fruit morphology, seed color, seed coat color, leaf margin morphology, branch number, fruit shattering, silique morphology, peduncle length, whole plant size, and responses to boron and potassium. Additional associations include abscisic acid breakdown, proanthocyanidin regulation, seed dormancy release, and cytokinin response. Related genes in other species are linked to pod shatter resistance, seed yield, leaf longevity, temperature-responsive flowering, and nematode resistance.
