RALF1 — Phaseolus vulgaris

Summary

PHAVU_008G122900, designated PvRALF1 on chromosome 8 of French bean, encodes a protein with receptor ligand and hormone activities. The gene is associated with cell-cell signaling, circadian regulation of gene expression, nitrogen fixation, nodulation, root development, stomatal movement, and defence response to fungi. PvRALF1 is linked to traits including root hair length, root thickness, cellulose content, flowering time, vegetative growth time, and responses to phosphorus, cadmium, ethylene, brassinosteroids, low temperature, and salt stress. The protein localizes to the apoplast, plasmodesma, filiform apparatus, and plasmalemma. Studies of related genes in other species link the family to root cell expansion, lateral root formation, cytoplasmic calcium signaling, mechanical signal transduction, and nematode resistance.
