COW1 — Phaseolus vulgaris

Summary

PHAVU_009G006100, designated PvCOW1 on chromosome 9 of French bean (Phaseolus vulgaris), encodes a protein with phosphatidylinositol carrier activity and phosphatidate binding, containing CRAL-TRIO and PI/PC transfer domains. The gene is associated with phospholipid transport, phosphatidylcholine anabolism, root hair elongation, cell tip growth, root epidermal cell differentiation, hyphal growth, flower development, and chromatin modeling. Its product localizes to the root hair tip, endoplasmic reticulum, Golgi complex, mitochondria, and plasmalemma. PvCOW1 is associated with root hair tip growth, root hair morphology, and autophagy. Related genes in other species link the family to root hair development, root system morphology, root hair length, chloroplast development, drought tolerance, flowering time, and callus induction.
