🧪🌾PAPER - What makes a tree a tree?🧬

Read the paper by @siribirkeland.bsky.social and @trhvidsten.bsky.social with contributions from several UPSC researchers.

By comparing dozens of genomes, they offer fresh insights into the genetic foundations of woodiness and perenniality in angiosperms.
Tree evolution is surprisingly quirky! 🌳 Trees are likely ancestral in many plant groups, often re-evolve on islands, and Arabidopsis can be made tree-like by tweaking a few genes. We revisited what genes really make a tree a tree using comparative genomics. @trhvidsten.bsky.social #trees #evolution

Opinion: Genomic studies hint at what makes a tree a tree | Plantae
This is such an engaging and though-provoking review article. I’d love to ask a group of students to think about what makes a tree a tree, including such questions as: How do we define trees?

🧪🌾 In collaboration with bioinformatician @trhvidsten.bsky.social, the team developed an interactive app that allows to explore seasonal gene activities and also to see which genes might be connected or influence each other. 🧬

🧪🌾 NEWS - A genetic roadmap across seasons 🧬

By comparing trees grown outdoors and in lab environments, they reveal seasonal genetic patterns and highlight both the strengths and limitations of lab-based experiments to study seasonality.

We have over the past month or so published a nice bouquet of papers about the interaction between the Atlantic salmon, its gut microbiome and the feed it eats.

Thrilled to see this paper out! 🎉

We analyzed 470 (!) angiosperm genomes and identified and dated 132 whole-genome duplication events. Importantly, we observed that WGD occurrence dates are not randomly distributed, but clustered at times of major environmental upheaval.
