    A conserved filamentous assembly underlies the structure of the meiotic chromosome axis

    Alan MV West et al.
    Meiotic chromosome axis 'core' proteins from fungi, plants, and mammals form a conserved filament architecture, and use a common mechanism to recruit HORMAD proteins for meiotic recombination control.

    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.

    Local chromosome context is a major determinant of crossover pathway biochemistry during budding yeast meiosis

    Darpan Medhi et al.
    Different homologous recombination pathways are dominant in different regions of meiotic chromosomes, indicating that chromosome structure influences recombination biochemistry.

    Single-molecule observation of DNA compaction by meiotic protein SYCP3

    Johanna L Syrjänen et al.
    Building on previous work (Syrjänen, Pellegrini, & Davies, 2014), it is shown that SYCP3 contributes to the architecture of meiotic chromosomes through local bridging interactions that result in large-scale compaction of the chromosome axis.
