#ERGAReads | Despite rapid chromosome changes, sedges maintain conserved synteny - likely due to repetitive DNA shaping recombination and gene order. This may explain how they retain species cohesion despite high rates of #chromosome evolution. ๐งฌ

Camille Cornet, @KayLucek, Paula Escuer & I had the pleasure of organising the first conference on holocentric chromosomes in @UniNeuchatel . 2 days of terrific talks & ๐ฃ๏ธ all about holocentricity, its #evolution across the Tree of Life, role in #speciation & #adaptation ๐๐พ๐ฑ๐ฆ๐ท๏ธ
๐จ New ERGA-BGE study alert! ๐จ @BioGenEurope
The reference genome of Erebia palarica, a montane butterfly endemic to North-West Iberia ๐ฆ, is now available.
Explore its insights for biodiversity ๐โจ

@snsf@AliceLaigle@CharJWright@TrendsGenetics For me personally, I started thinking about genomic rearrangements, & 3D genome structures during my @MSCActions grant at the Natural History Museum London during wonderful discussions with @jeff_streicher & @anjgoswami ! Thank you so much for planting this seed in my head! ๐๐พ4/4
We thank the Fondation Pierre Mercier pour la Science & @SNSF for funding, @AliceLaigle & @CharJWright for giving precious feedback on earlier drafts, & the editorial team of @TrendsGenetics for smooth processingย 3/4
Complex interactions b/w 3D genome structures & sequence evol., genomic rearrangements, & processes such as recombination suppression intrigued us. We immensely enjoyed writing this work! Hope it evokes such intrigue in you & opens a new perspective for speciation research! 2/4
๐จ ๐งต We (@CamilleCornet17 , @scueridae , @KayLucek & I) are delighted to share our perspectives on how the 3D genome structure could be both a cause & a consequence of speciation, just out in @TrendsGenetics !!Keeping reading ๐๐พ https://t.co/6ptS48xn1c 1/4
7/7 Overall, we show that fusions and fissions can have a considerable impact on speciation rates, particularly when groups are chromosomally diverse, and that the importance of fusions and fissions can differ even among clades within a single genus.
6/7 The pattern becomes more complicated when clades within Erebia are considered: karyotypically diverse clades (e.g. the purple clade) show higher associated speciation rates while in more conservative clades (e.g. the red clade) diversification is driven more by other factors.
5/7 We found that, while most chromosomal change across Erebia is anagenetic, fusions and fissions seem to differ in the degree to which they are cladogenetic, with fissions being more directly linked to speciation.
