BLR — Oryza sativa Indica Group

Summary

BGIOSGA031494 (BLR) on indica rice chromosome 10 encodes a homeobox domain-containing protein with TALE homeobox and KN_HD domains, annotated as a DNA-binding transcription factor with RNA polymerase II-specific activity, protein heterodimerization activity, and glycine hydroxymethyltransferase activity. The gene is associated with grain shattering, awn length, seed traits, and leaf margin serration. It is linked to carpel and flower morphology, floral organ identity maintenance, inflorescence meristem identity, auxin signaling regulation, and gibberellic acid content. Associations also include shoot apical meristem development, abscission-zone development, lignin deposition, drought response, pectin methylesterification, seed mucilage adherence, and organ separation. Studies of related genes in other species connect the family to meristem development, leaf shape, phyllotaxy, floral specification, and vascular development.
