BLR — Oryza sativa Indica Group

Summary

BGIOSGA013510 (BLR, also known as OiBLR, OiBLH9, OiBLH8, HB-6, VAN, OiVAN, OiBLH5, OiPNF, OiBLH4, PNF, RPL, OiBEL1) on chromosome 3 of Indica rice encodes a protein with a TALE homeobox domain and is associated with DNA-binding transcription factor activity, transcription regulator activity, transcription coactivator activity, glycine hydroxymethyltransferase activity, and poly(U) binding. The gene is linked to grain shattering, awn development, seed traits, and abscission-zone development, as well as to leaf margin serration, gibberellin homeostasis, and pectin methylesterification. It is associated with floral organ identity and morphogenesis, inflorescence and shoot meristem maintenance, and responses to ethylene and far-red light. Associations with panicle number, peduncle length, shoot growth angle, seed longevity, and compound leaf morphology have also been noted. Related genes in other species link the family to spindle assembly and male fertility.
