Autopolyploid establishment under gametophytic self-incompatibility: the impact of self-fertilization and pollen limitation Polyploidy is widespread in plants, yet the establishment of neo-polyploids is limited by minority cytotype exclusion (MCE). As polyploidy has been associated with higher selfing rates in empirical st...

The second Ph.D. chapter of Diane's thesis is out as a preprint. She studied the joint evolution of autopolyploidy and self-fertilization under a gametophytic self-incompatibility context.

Feel free to comment, and congratulations, Diane!

Friday Flower 007: Petunia 💮✨

Petunias carry the active transposon dTph1, which powers mutant screens and paints stripey patterns as it jumps.

Their five petals are fused, with diverse color designs tracing the corolla’s fusion seam.

Does population size shape protein coevolution?
I explored this in my talk today at the MPI for Evolutionary Biology.
Our work in mammals suggests the answer is yes - genetic drift is a major determinant of compensatory mutations.

I'd love to know if it increases transfo rate!

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!

Transposable elements are vectors of recurrent transgenerational epigenetic inheritance DNA methylation loss at transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants and significance of this additional system of inheritan...

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!

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Rapid establishment of species barriers in plants compared with that in animals Speciation, the process by which new reproductively isolated species emerge from ancestral populations, results from the gradual accumulation of barriers to gene flow within genomes. To date, the noti...

Check out this cool work from @crouxevo.bsky.social and others, congrats!!! 🥳

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

The BM^2 Lab is hiring a Ph.D. student to work on a variety of problems connected to modeling of morphogenesis in plants (i.e. ovule curvature formation, fixed handedness establishment in certain plant organs and its link to cell wall mechanics).

Please share!

Congratulations, that is amazing!

‘Almost unimaginable’: these ants are different species but share a mother Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

woah this is genuinely, utterly WILD

Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers!

This is so gloriously weird I can't quite compute it 🤯🧪🐜
