Evidence for de novo evolution of testis-expressed genes in the Drosophila yakuba/Drosophila erecta clade.

abstract：:We describe here a new variant of transposon Tn10 especially adapted for transposon analysis of cloned yeast genes; it can equally well be used for analysis of prokaryotic genes. We have applied this element to analysis of the LEU2, RAD50, and CDC48 genes of Saccharomyces cerevisiae. This transposon, nicknamed mini-Tn...
