Sun W.J., Wang C.X., and Li J.W., 2025, Molecular functions and regulatory mechanisms of the temperature-sensitive male sterility gene OsTms6 in rice, Rice Genomics and Genetics, 16(2): 86-95 (doi: 10.5376/rgg.2025.16.0008)

The temperature-sensitive male sterility gene OsTms6 plays a crucial role in the reproductive development of rice (Oryza sativa L.), particularly under varying thermal conditions. This systematic review synthesizes current research on the molecular functions and regulatory mechanisms of OsTms6. The gene has been identified as a key factor in hybrid rice production, with its sterility phenotype being influenced by specific temperature thresholds. Genetic mapping has localized OsTms6 to chromosome 10, and molecular analyses have revealed its interaction with various regulatory pathways, including those involving noncoding RNAs and microRNAs. The gene's role in pollen fertility is mediated through complex genetic and environmental interactions, which are critical for the development of temperature-sensitive genic male sterile (TGMS) lines. Understanding these mechanisms provides valuable insights for breeding strategies aimed at improving rice yield and resilience to climate change.
