CEP-CEPR1 signalling inhibits the sucrose-dependent enhancement of lateral root growth

Chapman, Kelly; Taleski, Michael; Ogilvie, Huw; Imin, Nijat; Djordjevic, Michael


Lateral root (LR) proliferation is a major determinant of soil nutrient uptake. How resource allocation controls the extent of LR growth remains unresolved. We used genetic, physiological, transcriptomic, and grafting approaches to define a role for C-TERMINALLY ENCODED PEPTIDE RECEPTOR 1 (CEPR1) in controlling sucrose-dependent LR growth. CEPR1 inhibited LR growth in response to applied sucrose, other metabolizable sugars, and elevated light intensity. Pathways through CEPR1 restricted LR...[Show more]
