RALF1 — Phaseolus vulgaris

Summary

PHAVU_006G089900, designated PvRALF1 on chromosome 6 of French bean, encodes a protein with receptor ligand and hormone activities. The gene is associated with cell-cell signaling, regulation of signaling receptor activity, calcium signaling, and protein autophosphorylation. PvRALF1 is linked to nitrogen fixation and nodulation, root development, stomatal movement, circadian regulation of gene expression, and responses to brassinosteroid and ethylene. It is also associated with defence response to fungi. The protein localizes to the apoplast, plasmodesma, filiform apparatus, and plasmalemma. Associations include root hair length, root thickness, flowering time, vegetative growth time, cellulose content, cadmium concentration, and responses to phosphorus, salt, low temperature, and powdery mildew. Studies of related genes in other species link the family to root cell expansion, lateral root formation, cytoplasmic calcium signaling, and mechanical signal transduction.
