A cross-species approach for the identification of Drosophila male sterility genes.

ABSTRACT: Male reproduction encompasses many essential cellular processes and interactions. As a focal point for these events, sperm offer opportunities for advancing our understanding of sexual reproduction at multiple levels during development. Using male sterility genes identified in human, mouse, and fruit fly databases as a starting point, 103 Drosophila melanogaster genes were screened for their association with male sterility by tissue-specific RNAi knockdown and CRISPR/Cas9-mediated mutagenesis. This list included 56 genes associated with male infertility in the human databases, but not found in the Drosophila database, resulting in the discovery of 63 new genes associated with male fertility in Drosophila. The phenotypes identified were categorized into six distinct classes affecting sperm
