摘　　要：Anther development and male fertility are essential biological pro- cesses for flowering plants and are important for crop seed produc- tion. Genetic manipulation of male fertility/sterility is critical for crop hybrid breeding. Rice （Oryza sativa L.） male sterility phenotypes, including genic male sterility, hybrid male sterility, and cytoplasmic male sterility, are generally caused by mutations of fertility-related genes, by incompatible interactions between divergent allelic or non-allelic genes, or by genetic incompatibilities between cytoplas-mic and nuclear genomes. Here, we review the recent advances in the molecular basis of anther development and male fertility-sterility conversion in specific genetic backgrounds, and the interactions with certain environmental factors. The highlighted findings in this review have significant implications in both basic studies and rice genetic improvement.Anther development and male fertility are essential biological pro- cesses for flowering plants and are important for crop seed produc- tion.
