Absence of chromosome axis proteins recruitment prevents meiotic recombination chromosome-wide in the budding yeast Lachancea kluyveri (CC-Seq)
Ontology highlight
ABSTRACT: Here we studied the budding yeast Lachancea kluyveri, a cousin of the model Saccharomyces cerevisiae, in order to try to understand the mechanism responsible for the absence of meiotic recombination on its almost entire sex chromosome (Brion et al. 2017). We performed meiotic DSB mapping using CC-seq (Gittens 2019). Briefly, we observed a distribution of meiotic DSBs mainly in gene promoters as in S. cerevisiae and a depletion within Lakl0C-left (the 1 Mb long domain on the sex chromosome with no meiotic recombination). Also, we noted a poor conservation of DSB hotspots strength between L. kluyveri and S. cerevisiae.
