New OA Article: "Transport of phenoxyacetic acid herbicides by PIN auxin transporters" rdcu.be/eiJXf
PINs are key players in distributing phenoxyacetic acid herbicides. Mutagenesis and cryo-EM structures elucidate substrate specificity and transport mechanisms. #PlantScience

Tang, Chen, and Friml show that moss' special superpower of de-differentiation and regeneration depends on auxin transport. I missed this preprint from a week ago (in Cell Biology subject instead of Plant Biology).
