The SABRE gene is necessary for plants to coordinate the polarity of their cells, a plant physiologist shows in his doctoral thesis. The gene “tells” all cells in a certain region what is up and what is down and how they should modify their form accordingly. Plant cell growth is often coordinated within a tissue layer, a concept that researchers name planar polarity.
