Abstract: Bag-of-marbles (Bam) is a regulatory factor during gametogenesis in Drosophila， which shows no significant homology to other known proteins. The bam gene has not been identified in other species since it was cloned from Drosophila in 1990. Recent researches show that Bam plays different roles in oogenesis and spermatogenesis. In female Drosophila， Bam regulates the differentiation from the germline stem cell to cystoblast， and also promotes incomplete cytokinesis in the cystoblast. However， in male Drosophila， Bam is responsible for the transition of spermatogonium from mitosis to meiois.
