The X chromosome of Drosophila shows a deficiency of genes with male-biased expression, whereas mammalian X chromosomes are enriched for spermatogenesis genes expressed premeiosis and multicopy testis genes. Meiotic X-inactivation and sexual antagonism can only partly account for these patterns. Here, we show that dosage compensation (DC) in Drosophila may(More)
Genome duplication is a powerful evolutionary force and is arguably most prominent in plants, where several ancient whole-genome duplication events have been documented. Models of gene evolution predict that functional divergence between duplicates (subfunctionalization) is caused by the loss of regulatory elements. Studies of conserved non-coding sequences(More)
BACKGROUND Transposable Elements (TEs) make up the majority of plant genomes, and thus understanding TE evolutionary dynamics is key to understanding plant genome evolution. Plant reproductive systems are diverse and mating type variation is one factor among many hypothesized to influence TE evolutionary dynamics. Here, we collected a large TE-display data(More)
