OS10G0575000 — Oryza sativa Japonica

Summary

OsATR2 (also known as OsMYC3, OsMYC4, OsMYC5, OsJAI1, OsbHLH009, OsbHLH014, OsNIG1, OsRD22BP1, and JIN1) on rice chromosome 10 encodes a protein with domains including AIB/MYC-like, MYC/MYB_N, bHLH-TF_ACT-like_plant, bHLH_dom, and HLH_DNA-bd_sf. The product is associated with bHLH transcription factor binding, histidine phosphotransfer kinase activity, MAPKK activity, transcription corepressor and coactivator activities, SUMO transferase activity, and histone binding. In rice, the gene is linked to jasmonic acid signalling, defence responses, bacterial blight resistance, phosphate starvation, spikelet morphogenesis, and drought recovery. It is also associated with regulation of glucosinolate biosynthesis, tryptophan formation, cytokinin signalling, ascorbate biosynthesis, seed maturation, and trichome spacing. Studies of related genes in other species link the family to drought tolerance, seed oil accumulation, resistance to bacterial pathogens, photomorphogenesis, and responses to nutrient deficiencies.
