TIP3 — Phaseolus vulgaris

Summary

PHAVU_004G136000, symbol TIP3, encodes a protein from the aquaporin family, possessing channel and water channel activity. In French bean (Phaseolus vulgaris) on chromosome 4, PvTIP3 is associated with water transport, protein storage, and protein targeting to the protein storage vacuole membrane and central vacuole. It is linked to seed maturation, cotyledon development, embryogenesis, autophagy, and Golgi-to-vacuole transport. The gene has been connected to responses to salt and thirst, as well as protein phosphorylation. Associations include protein content, seed longevity, seed germination, and seed development. Studies of related genes in other species link the family to vacuolar membrane transport and seed growth and development traits.
