TMS5 — Oryza sativa Indica Group

Summary

BGIOSGA007783 (TMS5, also known as NAC23) on chromosome 2 of indica rice encodes a NAC-domain transcription factor with sequence-specific DNA-binding activity. The gene is associated with thermo-sensitive genic male sterility, organ size, sugar, and phosphatase activity. It is linked to regulation of seed development, reproductive structure development, defence response to fungi, ABA signalling, root development, and responses to cold and salinity. Associations with grain yield and heterosis are also recorded. The protein localises to the cytoplasm. Studies of related genes in other species connect the family to drought tolerance, root number, and temperature-sensitive male sterility.
