J — Brassica juncea

Summary

BJUA03G11130S, also known as BjAGL24 or J, is located on chromosome A03 of Indian mustard (Brassica juncea). It encodes a MADS-box transcription factor containing K-box and MEF2-like domains, with annotated molecular functions including DNA-binding transcription factor activity, RNA polymerase II-specific, and transcription corepressor activity. The gene is associated with the regulation of flowering time, photoperiodism, vernalization response, and floral meristem identity maintenance. It has been linked to numerous traits including days to flowering, flower and inflorescence morphology, petal number, leaf morphology, seed development, sulfur content, water use efficiency, photosynthetic rate, and responses to abiotic stresses such as cold, high temperature, and drought. Additional associations include ethylene and abscisic acid sensitivity, anthocyanin content, and aphid response. Related genes in other species connect the family to floral organ patterning, meristem cell number, and primary root growth.
