BLR — Oryza sativa Japonica

Summary

OS01G0848400, also known as BLR, qSH1, and several other synonyms, encodes a TALE homeobox transcription factor with a POX domain, annotated with DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, and protein heterodimerization activity. In rice, this gene is directly associated with shattering, seed, and awn phenotypes. It is linked to diverse biological processes including specification of carpel identity, floral whorl morphogenesis, plant organ formation, proximodistal axis specification, negative regulation of auxin-mediated signaling, and response to ethylene stimulus. Associations extend to traits such as grain shattering, seedling height, root weight, shoot growth angle, seed longevity, and gibberellic acid content. The encoded protein localizes to the nucleolus, microtubule cytoskeleton, and chloroplast thylakoid. Studies of related genes in other species connect the family to leaf morphology, apical meristem development, and seed dispersal.
