Auxin fluctuation and PIN polarization in moss leaf cell reprogramming Abstract. Auxin and its PIN-FORMED (PIN) exporters are essential for tissue repair and regeneration in flowering plants. To gain insight into the evolution

PINpointing the highs and lows of #auxin 🧷

Tang et al investigated the role of auxin and PIN proteins in #moss cell reprogramming & regeneration; they found PpPINA levels & polarity to be pivotal to this process
