In the absence of recombination, the number of transposable elements (TEs) increases, but their accumulation dynamics are not well characterized. This study shows that TEs rapidly accumulated in non-recombining fungal mating-type chromosomes before reaching a plateau, possibly forming a TE reservoir.
Tetrapolar #fungi with multi-allelic little degenerated HD loci and biallelic highly degenerated PR, fascinating work from @schwessinger team

Ps. We think Pst 134E chromosomes 9 n Figure 5 should be flipped

Our first @PeerCommunityJournal lead by PhD student @[email protected] shows that linkage to a permanently heterozygous site decreases the purging probability and increases the purging time of mutations under selfing #seXYevol
