Analysis of PLETHORA Gradient Formation by Secreted Peptides During Root Development
The formation of longitudinal zonation patterns is important for normal root development and is regulated by the transcription factor PLETHORA (PLT). PLT proteins form a concentration gradient, and PLT protein levels determine root zonation. A peptide hormone root meristem growth factor (RGF) and its receptors (RGFRs) act as key regulators of root development by regulating the PLT protein expression pattern. Here, we describe a method for monitoring PLT protein gradient patterns in Arabidopsis with exogenous RGF treatment.
