Recently evolved genes identified from Drosophila yakuba and D. erecta accessory gland expressed sequence tags.

ABSTRACT: The fraction of the genome associated with male reproduction in Drosophila may be unusually dynamic. For example, male reproduction-related genes show higher-than-average rates of protein divergence and gene expression evolution compared to most Drosophila genes. Drosophila male reproduction may also be enriched for novel genetic functions. Our earlier work, based on accessory gland protein genes (Acp's) in D. simulans and D. melanogaster, suggested that the melanogaster subgroup Acp's may be lost and/or gained on a relatively rapid timescale. Here we investigate this possibility more thoroughly through description of the accessory gland transcriptome in two melanogaster subgroup species, D. yakuba and D. erecta. A genomic analysis of previously unknown genes isolated from cDNA libraries o
