JAMYB — Oryza sativa Indica Group

Summary

BGIOSGA035678 (JAMYB, OiJAMYB) on chromosome 11 of Indica rice encodes a protein with sequence-specific DNA-binding activity and transcription factor activity, belonging to the EOBI/EOBII-like plant family. It is associated with regulation of phenylpropanoid metabolism, shikimate metabolism, anthocyanin anabolism, pigmentation, green leaf volatile biosynthetic process, floral organ senescence, regulation of cell wall organization or biogenesis, circadian rhythm, response to jasmonic acid, activation of salinity response, and cellular response to virus. It localizes to the nucleus and plant-type cell wall. Associations with grain length, grain size, and hull color have been noted, as well as links to seedling salinity, bacterial blight, and blast phenotypes. Studies of related genes in other species connect this gene family to seed weight, drought tolerance, heat tolerance, chlorophyll content, and fungal disease response.
