BLR — Oryza sativa Indica Group

Summary

BGIOSGA003575 (BLR, also known as OiBLR, OiBLH9, and other synonyms) on indica rice chromosome 1 encodes an uncharacterized protein with DNA-binding transcription factor activity, transcription regulator activity, and glycine hydroxymethyltransferase activity. The gene is associated with diverse biological processes including glycine metabolism, specification of carpel identity, leaf formation, and cytokinin anabolism. BLR is associated with numerous agronomic traits such as grain shattering, awn length, panicle number, seed longevity, and shoot growth angle. It is also linked to phenotypes including seed shattering, abscission-zone development, lignin, drought response, and pectin methylesterification. Studies of related genes in other species link the family to spindle assembly and male fertility, while sequence similarity connections associate the family with grain number, plant height, cold tolerance, and tiller number.
