An early Christmas present from our team for all of the tomato šŸ… & recombination fans: Chromosome-scale Solanum pennellii and Solanum cheesmaniae genome assemblies reveal structural variants, repeat content and recombination barriers of the tomato clade biorxiv.org/content/10.648ā€¦
Paper alert! #Meiosis4Ever Maximizing meiotic crossover rates reveals the map of Crossover Potential Juli Jing, Qiachao Lian and Stephanie Durand www.nature.com/articles/s41... We pushed meiotic crossover as much has we could, and had some surprises A thread šŸ‘‡
"Haploid induction in sweet potato by activating the AP2/ERF family transcription factor IbBBM" From: onlinelibrary.wiley.com/doi/full/10.... Since sweet potato is hexaploid, the corresponding haploid is actually triploid then?
Excited to share that our COmapper preprint on bioRxiv has been updated following two rounds of major revisionā€”thanks to insightful peer reviews! biorxiv.org/content/10.1... COmapper is now even betterā€”check it out on GitHub: github.com/KyuhaChoi-La... Journal version coming soon!

Our study on COmapper using nanopore long-read sequencing is now published online! (see New Phytologist: nph.onlinelibrary.wiley.com/doi/10.1111/...) Congratulations to lead author Dohwan Byun, soon-to-be Dr. Namil Son, and the co-authors!
It is sad that even basic research needs to be defended with utility. For me, basic research is in the same category as art: civilized societies can't do without it, because we all want to know who we are and what our place in the natural world is -- questions that only science can answer.
Please see our latest paper on the role of EXO1 in meiosis: "EXO1 promotes the meiotic MLH1-MLH3 endonuclease through conserved interactions with MLH1, MSH4 and DNA". Congratulations to both first authors, Megha Roy and Aurore Sanchez and thanks to all our collaborators!
We have a complete program ! meiosis.cornell.edu/mayosis2025/... The #Mayosis25 seminar series will open with a tribute to Scott Hawley by @jeffsekelsky.bsky.social. Congrats to all the selected speakers and we look forward to hearing about your fantastic science ! #Meiosis4ever
New preprint on 3D heterochromatin architecture in human cells! Great collab with @sergiocruzleon.bsky.social & @johannesbetz.bsky.social from @hummerlab.bsky.social, @marinalusic.bsky.social & the TuroňovĆ” lab. Many thanks to my supervisor @becklab.bsky.social. bioRxiv: tinyurl.com/3a74uanv šŸ§µšŸ‘‡
