An updated perspective: what genes make a tree a tree? #plantscience
An updated perspective: what genes make a tree a tree?
We learn early on how to tell trees apart from other plants. However, it has proved hard to distinguish trees from other plants at the genetic level, and it is believed that there are no unique ‘tree genes’. With the rapid increase in available tree genomes, we can perform new comparative and evolutionary analyses of plant life histories and growth forms. Here we provide a fresh perspective on the genetic foundation for woodiness and perenniality in angiosperms by analyzing selection pressures and gene family evolution in the rosids using genomic data. We examine genes distinguishing trees from herbs and discuss future directions for uncovering the genetic factors that define a tree in this new era of tree genomics.

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

🧪🌾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.
