Very happy to share that the @erc.europa.eu has selected PHYTOPOGON for funding! 😁🌱 In this project, we will test whether plants have greenbeard genes — an evolutionary mechanism that could allow them to recognize the genetic identity of their neighbours.

Our study on the evolution of shade avoidance, a "selfish trait" in plants, over 80 years of soybean breeding history. Led by @lukecoevo.bsky.social and Emanuel Kopp, and published here: doi.org/10.1111/eva..... Great stuff!

Shade Avoidance Restricts Soybean Breeding Progress and Increases Herbivore Susceptibility
High planting densities expose field crops to competition for light, which typically induces shade avoidance responses such as stem elongation. While adaptive in natural environments, these responses...

Many organisms, including humans, reshape their environments in ways that influence the conditions faced by future generations. We ask whether this can favour biological variation with @irisprigent.bsky.social in our new paper. Thanks to @dee-unil.bsky.social @snsf.ch www.pnas.org/doi/full/10....

A sex-determining gene region in ants, bees, and wasps has maintained its function for over 150 million years through its chromosomal position rather than its DNA sequence, as evidenced by the lack of sequence homology among lineages. In PNAS: ow.ly/n9eU50XWipU
A member of the Hymenoptera order, Colletes cunicularius, has an evolutionarily conserved sex-determination mechanism.

New paper out in @jxbotany.bsky.social! 🌱🌾 We found that mixing different wheat varieties can decrease belowground competition at early growth stages, especially under resource limited conditions.
