  text: "Insects of the order Hemiptera (true bugs) use a wide range of mechanisms
    of sex determination, including genetic sex determination, paternal genome elimination,
    and haplodiploidy. Genetic sex determination, the prevalent mode, is generally
    controlled by a pair of XY sex chromosomes or by an XX/X0 system, but different
    configurations that include additional sex chromosomes are also present. Although
    this diversity of sex determining systems has been extensively studied at the
    cytogenetic level, only the X chromosome of the model pea aphid Acyrthosiphon
    pisum has been analyzed at the genomic level, and little is known about X chromosome
    biology in the rest of the order.\r\n\r\nIn this study, we take advantage of published
    DNA- and RNA-seq data from three additional Hemiptera species to perform a comparative
    analysis of the gene content and expression of the X chromosome throughout this
    clade. We find that, despite showing evidence of dosage compensation, the X chromosomes
    of these species show female-biased expression, and a deficit of male-biased genes,
    in direct contrast to the pea aphid X. We further detect an excess of shared gene
    content between these very distant species, suggesting that despite the diversity
    of sex determining systems, the same chromosomal element is used as the X throughout
    a large portion of the order. "
