Bacteria are amazing! The abundant Dps protein binds and protects DNA in stationary-phase cells with minimal effect on chromosome accessibility, dynamics, and organization. Now in NAR doi.org/10.1093/nar/...; I'm really proud of our multidisciplinary team led by Lauren, Lindsay, and Xiaofeng, et al.

🚨 First pre-print from my team !!

TL;DR: presence of polymorphism (sequence differences between the homologous chromosomes) can *increase* the local rate of recombination in Arabidopsis thaliana, turning cold regions of the genome hot (purple v. grey) !
The recombination frequency (cM/Mb) along chromosome 4 of A. thaliana (female meiosis). In full hybrids (grey), where polymorphism is distributed all along chromosomes, most crossovers occur in the regions surrounding the Centromere (Cen), and very few at chromosome ends (Tel: telomeres). In lines where polymorphism is restricted to chromosome ends (purple), the local recombination rate increases drastically, at the expense of the non-polymorphic regions (yellow).
