Tissue- and Stage-Dependent Dosage Compensation on the Neo-X Chromosome in Drosophila pseudoobscura

Sex chromosome dosage compensation (DC) is widely accepted in various organisms. This concept is mostly supported by comparisons of gene expression between chromosomes and between sexes. However, genes on the X chromosome and autosomes are mostly not homologous, and the average gene expression level on these chromosomes may not be the same even under DC, which complicates...

Unusual Evolution of Interspersed Repeat Sequences in the Drosophila ananassae Subgroup

New repeat sequences were found in the Drosophila ananassae genome sequence. They accounted for approximately 1.2% of the D. ananassae genome and were estimated to be more abundant in genomes of its closely related species belonging to the Drosophila bipectinata complex, whereas it was entirely absent in the Drosophila melanogaster genome. They were interspersed throughout...
