The TaCLE24b peptide signaling cascade modulates lateral root development and drought tolerance in wheat.

ABSTRACT: Plant peptide hormones play an important role in regulating root development and stress responses. Here, we identify a root-derived CLAVATA3/Endosperm surrounding region-related (CLE) peptide TaCLE24b and its leucine-rich repeat receptor-like kinase CLAVATA1 (CLV1) TaCLV1, which together regulate the formation of lateral root primordium and the outgrowth of lateral root in wheat. Additionally, a loss-of-function mutation of TaSG-D1, encoding a Ser/Thr protein kinase glycogen synthase kinase 3 (STKc_GSK3), also enhances the formation of lateral root primordium and the outgrowth of lateral roots in wheat. Furthermore, TaCLV1 interacts with TaSG-D1, leading to phosphorylation and degradation of TaSG-D1. Whereas the presence of TaCLE24b enhances the binding affinity and phosphorylation ability
