In all eukaryotes, histone variants are incorporated into a subset of nucleosomes to create functionally specialized regions of chromatin. One such variant, H2A.Z, replaces histone H2A and is required for viability in all metazoans tested to date. However, the function of H2A.Z in chromatin organiza...

Recent studies have revealed key roles of non-coding RNAs in sex-related pathways, but little is known about the evolutionary forces acting on these non-coding RNAs. We used whole-genome tiling arrays to profile the transcriptome of Drosophila melanogaster tissues and found that 15% of male-biased t...
