Assistant Professor Kuan-Ju Lu and his team investigated the polarized distribution of PIN auxin efflux carriers, which is essential for directional auxin transport and plant development. Through cross-species analyses in bryophytes and Arabidopsis, they showed that PIN polarization in moss depends on the cytoskeleton, whereas Arabidopsis PIN polarity does not exhibit the same dependence. Their findings further revealed that the mechanisms underlying PIN trafficking and polarization have diverged during land plant evolution. The study was published in Plant Communications (Tang et al., 2024).
