I'm frequently asked if we can use XRM imaging to study Arabidopsis, and the answer is absolutely yes. The pollen grains were segmented using basic grayscale thresholding. This scan used the 4X lens, stayed tuned for results from the 20X.

But I suspect that's not the common picture folks get of stuff like this - we think the protein is changed, rather than its regulation. Yet as we now know, it's very common for selection in metazoans actually to act via regulatory change. This is a neat example. 8/8

Wow this is quite amazing - I know almost nothing on recombination, but always assumed that the more similar the sequences were, the more likely they would recombine, turns out it's the opposite!

Chloe Girard, PhD @chloegirard.bsky.social · 10d

🚨 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).
