#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. 🧬

Camille Cornet, @KayLucek, Paula Escuer & I had the pleasure of organising the first conference on holocentric chromosomes in @UniNeuchatel . 2 days of terrific talks & 🗣️ all about holocentricity, its #evolution across the Tree of Life, role in #speciation & #adaptation 🙌🏾🌱🦋🕷️

[Kay Lucek @KayLucek]

Congratulations @crazy_chipkali for a great talk @Biology25UNIL 👏 #Holocentric #Carex 🧬🌱

[Kay Lucek @KayLucek]

Great effort! So eager to see #Erebia taking off

[European Reference Genome Atlas @erga_biodiv]

🚨 New ERGA-BGE study alert! 🚨 @BioGenEurope
The reference genome of Erebia palarica, a montane butterfly endemic to North-West Iberia 🦋, is now available.
Explore its insights for biodiversity 🌍✨

Throwback to last year's fieldwork in Georgia 🇬🇪 collecting Erebia 🦋 for genome annotation as part of our @BioGenEurope Case Study! Thanks to our Georgian experts Tina and @iankoshvili from CaBoL and to @REA_research, @SBFI_CH, @ISBSIB, @EUgreenresearch

[Kay Lucek @KayLucek]

Well done! Let's explore the role of 3D genomic changes during speciation in #holocentrics and beyond

[Camille Cornet @CamilleCornet17]

Happy to share our press release (in French) from @UniNeuchatel! We propose a new 3D genomics view to help understand species diversification 🧬🌱🦋 with @crazy_chipkali @scueridae @KayLucek

Looking forward to exciting discoveries in Erebia! Go team 🦋

[Camille Cornet @CamilleCornet17]

Very excited to start a @BioGenEurope case study with @KayLucek on the adaptive potential of alpine butterflies in changing environments! 🦋🏔️We will annotate genomes to showcase the importance of genomics for conservation 🧬 @REA_research, @SBFI_CH, @ISBSIB, @Eugreenresearch

[Ashwini V Mohan ಅಶ್ವಿನಿ 🦎🧬🙋🏾‍♀️ @crazy_chipkali]

@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! 🙌🏾4/4

[Ashwini V Mohan ಅಶ್ವಿನಿ 🦎🧬🙋🏾‍♀️ @crazy_chipkali]

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 processing  3/4

[Ashwini V Mohan ಅಶ್ವಿನಿ 🦎🧬🙋🏾‍♀️ @crazy_chipkali]

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

[Kay Lucek @KayLucek]

So exciting! What a great outcome of a group effort! Now we need to get the empirical side sorted 😊

[Ashwini V Mohan ಅಶ್ವಿನಿ 🦎🧬🙋🏾‍♀️ @crazy_chipkali]

🚨 🧵 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 👇🏾 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.

[Hannah Augustijnen @HAugustijnen]

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.

[Hannah Augustijnen @HAugustijnen]

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.
