Male and female reproductive structures play an important role in seed development in plants. Abnormalities in male or female reproductive structures can lead to sterility. In soybean, Glycine max (L.) Merr., about 75 sterility mutants have been identified and most of them have been mapped to chromosomes. Mapping results have shown that some chromosomal regions are hotspots for fertility genes. Fine mapping of some of the male-sterile, female-fertile mutants and male-sterile, femalesterile mutants resulted in identification of candidate genes for fertility. Sequence comparisons further helped in locating a few putative candidates. A CACTA- like transposable element that is responsible for ...
