Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Very happy to share that the work I've been doing with @saramitri.bsky.social is now out on biorxiv! www.biorxiv.org/content/10.6... We broadly ask how are microbial interactions distributed, is there a common shape across datasets, what drives it, and why it matters. Summary thread below 🧵 1/17

Metabolic processes shape microbial interaction distributions

Microbial communities are largely driven by metabolic interactions, whereby species compete for shared resources and exchange byproducts. Such interactions are commonly classified by their sign alone....

Some weeks ago I read a post here on biases in the selection of plants for research. In particular, it pointed out that researchers seem to prefer to work on species with large, showy flowers. I forgot to write it down, and now it would be useful for something I'm writing. Does anyone remember it?

Why do sex chromosomes stop recombining? New models show even weak sexual antagonism can strongly drive recombination suppression, with mating systems shaping the outcome. By @ewanflintham.bsky.social and @charlesmullon.bsky.social doi.org/10.1093/evle...

Sexual antagonism, mating systems, and recombination suppression on sex chromosomes

Abstract. The suppression of recombination between sex chromosomes is a widespread feature of genetic sex determination systems. Competing explanations for

New paper with the brilliant @ewanflintham.bsky.social How fast does recombination suppression evolve among sex chromosomes? We show that even weak sexual antagonism (so hard to detect) makes this fast, often via inversions fixing on X/Z depending on mating system: doi.org/10.1093/evle...

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...

Dominance modifiers at the Arabidopsis self-incompatibility locus retain proto-miRNA features and act through non-canonical pathways

Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...
