    Gene flow mediates the role of sex chromosome meiotic drive during complex speciation

    Colin D Meiklejohn et al.
    Selfish genetic elements may either promote or prevent the evolution of reproductive barriers, depending on the extent of gene flow between species.

    Dose-dependent action of the RNA binding protein FOX-1 to relay X-chromosome number and determine C. elegans sex

    Behnom Farboud et al.
    RNA binding protein FOX-1 functions as a dose-dependent X-signal element to communicate X-chromosome number and determine nematode sex by controlling alternative non-productive pre-mRNA splicing of the master sex-determination switch gene.
    1. Chromosomes and Gene Expression

    Cooperation between a hierarchical set of recruitment sites targets the X chromosome for dosage compensation

    Sarah Elizabeth Albritton et al.
    Gene regulatory elements can target a chromatin regulatory complex to a single chromosome in the genome through hierarchical specification and long distance cooperation.
    1. Evolutionary Biology

    Free-living human cells reconfigure their chromosomes in the evolution back to uni-cellularity

    Jin Xu et al.
    Human cell lines regress to become ‘de-sexualized’ by reconfiguring to a 2:3 X/A ratio of high fitness, thus shedding light on the evolution of mammalian sex chromosomes.

    Chromosome-wide mechanisms to decouple gene expression from gene dose during sex-chromosome evolution

    Bayly S Wheeler et al.
    A chromosome-wide mechanism balances X-linked gene expression between the sexes in C. elegans, but no similar chromosome-wide mechanism balances gene expression between X chromosomes and autosomes.

    Evolution of gene dosage on the Z-chromosome of schistosome parasites

    Marion A L Picard et al.
    An analysis of gene dosage at the DNA, RNA and protein level yields new insights into the early stages of Z-chromosome dosage compensation in schistosome parasites.

    GUY1 confers complete female lethality and is a strong candidate for a male-determining factor in Anopheles stephensi

    Frank Criscione et al.
    Evidence that the small GUY1 protein is a strong candidate for being a male-determining factor is provided via the establishment of Guy1 transgenic lines of mosquitoes that confer complete and stable female lethality.
    1. Chromosomes and Gene Expression

    Transcription dynamically patterns the meiotic chromosome-axis interface

    Xiaoji Sun et al.
    Distributed cohesin rings flexibly tether the axial element structure of meiotic chromosomes to the underlying chromatin to readily accommodate ongoing transcription.

    Chromatin-associated RNA sequencing (ChAR-seq) maps genome-wide RNA-to-DNA contacts

    Jason C Bell et al.
    ChAR-seq is a massively parallelized de novo RNA mapping assay, which is capable of generating hundreds to thousands of RNA-binding maps with no a priori knowledge of target RNAs.

    Evolutionary stasis of the pseudoautosomal boundary in strepsirrhine primates

    Rylan Shearn et al.
    A larger non-recombining region in sexually dimorphic primates compared to sexually monomorphic ones supports the view that sexually antagonistic mutations have influenced the evolution of sex chromosomes in primates.
