  • This study by Scacchi et al. shows that a mobile small-RNA-based Turing system dynamically organizes plant organ polarity. The afforded developmental flexibility accounts for diversity in organ shapes, from radialized or cup-shaped to the robust planar shape of a typical leaf.

  • The establishment of leaf adaxial–abaxial polarity happens early at the shoot apical meristem. Using quantitative live imaging of auxin and dorsiventral polarity markers, the authors trace the origin of polarity to before primordium emergence, to an overlay of high auxin onto a meristem periphery prepattern.
