I am excited to announce a job for an Asst Prof in Plant Evolution in the dept. of Evolution and Ecology at @ucdavis.bsky.social. We're looking broadly, from macro (speciation, comparative genomics, evo-devo) to micro (pop biology, adaptive evolution, evo-eco). recruit.ucdavis.edu/JPF07777

Although the red pigments made by flowering plants and liverworts are produced by distinct chemical pathways, here we found that they are induced by homologous complexes of transcription factors. @currentbiology.bsky.social

Replicated repurposing of an ancestral transcriptional complex in land plants

Kongsted et al. find that, while the red pigments produced in liverworts and seed plants are distinct, they are regulated by homologous MYB-bHLH transcriptional complexes. They also find that in liver...

In #GENETICS, @hildeschneemann.bsky.social and John Welch introduce a simple fitness landscape model to predict hybrid fitness with arbitrary ploidy and an arbitrary number of hybridizing lineages using data from #maize and rye. buff.ly/E24fZsM

I got to think about lots of cool/scary things working on this: (very) rapid adaptation, introgression of structural variants, invasive species, reproductive isolation, pesticide resistance, the precarity of food production. Grateful to have worked on such a big dataset with amazing collaborators

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same
