Abstract An Arabidopsis thaliana male sterile mutant EC2-157 has been isolated using an EMS mutagenesis strategy. Genetic analysis indicated that it was controlled by a single recessive gene called ms157. No pollen grains have been observed in mutant anthers. ms157 Has been mapped to a region of 74 kb located in BAC clone T6K22 on chromosome IV using a map-based cloning strategy. As no male sterile genes have been reported in this region, ms157 could be a novel gene related to fertility. The further molecular cloning and functional analysis on this gene should facilitate our understanding of A. thaliana anther development.
