BLR — Oryza sativa Indica Group

Summary

BGIOSGA011748 (BLR, also known as OiBLR) on indica rice chromosome 3 encodes a TALE homeobox transcription factor with a POX domain, homeodomain, and KN_HD domain, and is annotated with DNA-binding transcription factor activity, transcription regulator activity, and glycine hydroxymethyltransferase activity. The gene is associated with shattering, seed, and awn phenotypes, and with grain shattering, awn length, panicle number, seed longevity, and shoot growth angle. It has been linked to biological processes including specification of carpel identity, floral whorl morphogenesis, maintenance of inflorescence meristem identity, negative regulation of auxin-mediated signaling, and response to ethylene stimulus. Localization evidence connects the product to the condensed chromosome, microtubule cytoskeleton, and chloroplast thylakoid. Related genes in other species link the family to spindle assembly and male fertility.
