Our review on adaptive introgression in the context of climate adaptation is now published in Mol Ecol:
onlinelibrary.wiley.com/doi/10.1111/...

In a nutshell: often invoked theoretically, rarely unambiguously demonstrated empirically!

Many thanks to everyone who shared feedback on earlier versions

I'm not joking when I say mRNA technology is more important than "AI" and it's a tragedy we're throwing billions into one while our government is aggressively defunding the other.

Genome–host association mapping reveals wheat pathogen genes involved in host specialization - Nature Plants This study introduces genome–host association (GHA), leveraging natural epidemics to map the genetic landscape of host adaptation in the pathogen Zymoseptoria tritici. Applied to 832 wheat fungal stra...

Thrilled to share our paper now out in Nature Plants 🎉
We developed a genome-host association (GHA) approach to study pathogen adaptation directly from field metadata by using the originating host cultivar as phenotype.

In March, Matt Ridley gave the inaugural "Scientific Freedom Lecture" at NIH, on a lab leak origin of COVID-19.

The talk was so full of misrepresentations, omissions, falsehoods and lies that I will need several blog posts to debunk it. Here's Part I:

Ever wondered how the #cuticle, a hallmark of land plants, was established?

In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

Two models for the nature of pleiotropy in adaptation. Left: Schematic of the environmental structure in this study. Environments can be mapped onto a multidimensional environment space characterized by chemical and physical compositions. The large green circle represents an environment where adaptive mutants evolved, and the large pink circle is a distant environment. Around each base, a set of identical environmental perturbations (arrows) is applied, generating clusters of similar environments around distinct base environments. Top right: Schematic of fitnotype map for adaptive mutants near their home base environment. By measuring fitness in each of the green environments, one can infer how many fitnotypes matter for this set of mutants in their home environment. Here, only four of the possible 8 fitnotypes matter. Bottom right: When the mutants are moved to the distant base environment, and their fitness is measured in all pink environments (base and perturbations), there are two possibilities. Either more fitnotypes become important and the space appears higher-dimensional (left, pleiotropic expansion), or the set of fitnotypes that matters remains low-dimensional, but shifts (right, pleiotropic shift).

Predicting the effect of a #mutation on #fitness is hard. @oliviamghosh.bsky.social @petrovadmitri.bsky.social &co use fitness effects of adaptive yeast mutants to show that underlying genotype-phenotype-fitness maps are low-dimensional but context-dependent @plosbiology.org 🧪 plos.io/4dLy2Ez
