MYB — Oryza sativa Japonica

Summary

OsMYB (OS01G0863300) encodes a MYB-domain transcription factor with DNA-binding, protein homodimerization, and zinc-binding activities. In rice, it is associated with appendage development, anthocyanin breakdown, zeaxanthin anabolism, regulation of secondary growth, wax metabolism, and Casparian strip assembly. The gene is linked to numerous agronomic traits including panicle dry weight, grain yield, grain shape, amylose content, leaf and hull color, seed shattering, drought sensitivity, salt and heat tolerance, photosynthetic rate, and days to heading. It localizes to mitochondria and the cytosol. Related genes in other species connect the MYB family to fungal disease response, germination ratio, and grain iron and zinc content, as well as anthesis-silking interval and plant vigor.
