My team have a new paper out today in development on the evolution of branching, showing that bifurcation in the lycophyte Selaginella kraussiana is regulated by auxin transport and that PIN-mediated auxin transport is an ancestral regulator of branching within the vascular plants. Really proud of my post-doc Vicky Spencer who started the project in 2019 and did the work through the pandemic, and one of our undergraduates Lucy Spencer who helped out in her free time. The results from their careful surgical experiments are lush, and you can read about the work here @Dev_journal! Thanks @LeverhulmeTrust for funding our project.
