Characterization of CYCLOPHILLIN38 shows that a photosynthesis-derived systemic signal controls lateral root emergence.

Plant physiology - 15 Mar 2021

Duan Lina, Pérez-Ruiz Juan Manuel, Cejudo Francisco Javier, Dinneny José R

Abstract excerpt

Photosynthesis in leaves generates fixed-carbon resources and essential metabolites that support sink tissues, such as roots. Two of these metabolites, sucrose and auxin, promote growth in root systems, but the explicit connection between photosynthetic activity and control of root architecture has not been explored. Through a mutant screen to identify pathways regulating root system architecture, we identified a...
