Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis!

Excellent work from @piotraz.bsky.social group demonstrating juxtaposition of heterozygous & homozygous regions in maize attracts meiotic recombination to het regions rdcu.be/eHmn9 @natplants.nature.com builds from work we did together in Cambridge on Arabidopsis way back in 2015. Great stuff Piotr!

Thanks to @frm-officiel.bsky.social for financing such a (slightly overambitious) post-doc project!

Happy to share the results of a long-haul post-doc project, now online @science.org, aiming at understanding the rules of transgeneration epigenetic inheritance over TEs in plants and its extent and impact in nature. More below!

1/2 Somatic TE transposition in plants is getting traction again (70 years after McClintock's discovery of "controlling elements")! A very large collection of somatic TE insertions in A. thaliana described by Ambreen et al.(www.biorxiv.org/content/10.1...).

Partial redundancy buffers deleterious effects of mutating DNA methyltransferase 1-1 (MET1-1) in polyploid wheat Varying gene dosage through mutating DNA methyltransferase 1-1 (MET1-1 ) in polyploid wheat generates quantitative changes to CG methylation without the le

I’m very happy to share the published version of our paper on the role of MET1 in wheat 🌾 🧬

It’s been really exciting to discover more about DNA methylation in wheat and it’s huge polyploid genome

Beautiful pangenomic study! Congrats!

Interested in the contribution of TEs to the evolution of regulatory pathways in plants? 2-year post-doc position open in URGI in Versailles!

Postdoc jobs in the Gaut lab! Brandon isn't on here, so I can be frank: he is fantastic. I did my postdoc with him and he is not only an amazing scientist but one of my favorite humans. I would have happily stayed in his lab forever if that was feasible. recruit.ap.uci.edu/JPF08999 #plantscijobs
