JAMYB — Oryza sativa Indica Group

Summary

BGIOSGA035676 (symbol JAMYB, also known as OiJAMYB) on chromosome 11 of Indica rice encodes a DNA-binding transcription factor of the EOBI/EOBII-like plant family, containing a Myb domain and SANT/Myb domain. The gene is associated with regulation of phenylpropanoid metabolism, anthocyanin and lignin anabolism, shikimate metabolism, cell wall organization, floral organ senescence, pigmentation, green leaf volatile biosynthesis, circadian rhythm, and responses to jasmonic acid, salinity, virus, and thirst. It is linked to grain length, grain size, and hull color traits, as well as phenotypes including salinity, bacterial blight, blast, and lesion formation. The product localizes to the nucleus and plant-type cell wall. Studies of related genes in other species connect the family to seed weight, drought tolerance, heat tolerance, and fungal disease response.
