BLR — Brassica juncea

Summary

BJUA10G29300S (symbol BLR, also known as BjBLR, BjPNY, HB-6, VAN, BLH9, KN-1, LSN, BjVAN, BjLSN, RPL, BjRPL, BjBLH9) on Indian mustard chromosome A10 encodes a protein with a homeodomain and a KNOX domain, and is associated with DNA-binding transcription factor activity, transcription coactivator activity, poly(U) binding, and glycine hydroxymethyltransferase activity. It is associated with floral whorl morphogenesis, carpel development, maintenance of inflorescence meristem identity, adaxial/abaxial pattern specification, secondary shoot formation, xylem development, and negative regulation of auxin mediated signaling pathway. The gene is linked to traits including compound leaf morphology, flower and petal morphology, seed weight, pedicel length, shoot axis branching, lignin biosynthesis, photoperiod-sensitive flowering time, and biotic plant stress. It localizes to plasmodesmata, microtubule cytoskeleton, and chloroplast thylakoid. Studies of related genes in other species connect the family to organ separation, floral organ abscission, lateral root formation, and shoot apical meristem maintenance.
