A SOSEKI-based coordinate system interprets global polarity cues in Arabidopsis

Multicellular development requires coordinated cell polarization relative to body axes, and translation to oriented cell division1–3. In plants, it is unknown how cell polarities are connected to organismal axes and translated to division. Here, we identify Arabidopsis SOSEKI proteins that integrate apical–basal and radial organismal axes to localize to polar cell edges. Localization does not depend on tissue context, requires cell wall...
