RIC2 — Phaseolus vulgaris

Summary

PHAVU_008G018000, designated PvRIC2 on chromosome 8 of French bean (Phaseolus vulgaris), encodes a RIC2/4 family protein containing a CRIB domain. The product exhibits GTP binding, GTPase activity, GAP binding, and protein binding. PvRIC2 is associated with the regulation of actin polymerization and depolymerization, establishment of vesicle localization, regulation of exocytosis, and nodulation. It localizes to the cytoplasm, nucleus, nucleolus, mitochondria, plasmalemma, apical part of the cell, and spindle. The gene has been connected to seed growth and development, seed germination, pollen tube polar and tip growth, root hair development and branching, actin bundle formation, and fungal symbiosis. Related genes in other species are linked to pollen tube growth and resistance to Phytophthora infestans.
