COW1 — Phaseolus vulgaris

Summary

PHAVU_011G042900, designated PvCOW1, encodes a protein with phosphatidylinositol carrier activity and phosphatidate binding, belonging to the CRAL-TRIO and PI/PC transfer domain families. In French bean, this gene is associated with phospholipid transport, phosphatidylcholine anabolism, root hair elongation, cell tip growth, hyphal growth, root epidermal cell differentiation, flower development, and chromatin modeling. The encoded protein localizes to the root hair tip, endoplasmic reticulum, Golgi complex, mitochondria, and plasma membrane. Phenotypic associations include root hair tip growth, root hair morphology, and autophagy. Studies of related genes in other species link the family to root hair development, chloroplast development, protein secretion, and phosphatidylinositol transfer activity, while sequence similarity connections extend to traits such as root system morphology, root hair length, drought tolerance, flowering time, and callus induction.
