QUIRKY regulates root epidermal cell patterning through stabilizing SCRAMBLED to control CAPRICE movement in Arabidopsis

Abstract

SCM is a receptor-like kinase that ensures proper root patterning. Here, Song et al. find that SCM promotes the movement of CPC from non-hair cells to neighboring root epidermal cells and identify QKY as an additional facilitator of CPC mobility that acts by preventing vacuolar degradation of SCM.
