Temperature, light, and humidity significantly influence the expression of male sterility (MS) genes in rice. High temperatures were found to induce MS by disrupting pollen development and gene expression in the anther. Genes involved in sugar, lipid, phytohormone, and phenylpropanoid various metabolisms were differentially expressed under varying temperature, light, and humidity conditions, affecting pollen wall development and MS. For instance, cooling water temperature prior to panicle initiation was shown to affect chilling-induced MS, with stress-responsive genes being down-regulated under low water temperature conditions. The findings of valuable reports provide a comprehensive understanding of how temperature, light, and water or humidity regulate male sterility genes in rice. This review aims to elucidate the regulatory mechanisms of temperature, light, water or humidity on the expression of MS genes in rice, focusing on the interaction between environmental factors and genetic responses that govern MS, thereby enhancing two-line hybrid rice production and food security.
