| 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. |
