During development, gene expression must be carefully regulated to ensure that the right genes are expressed only at the correct time and in the correct place.. We performed a genome-wide analysis of gene expressionto identify germline- and sex-regulated genes.Using mutants that cause defects in germ cell proliferationor gametogenesis, we identiÞed sets of g Acknowledgement.
