AQP1 — Phaseolus vulgaris

Summary

PHAVU_001G181100, designated PvAQP1 (also known as PvTIP1 or TIP1-1) on French bean chromosome 1, encodes a tonoplast intrinsic protein belonging to the aquaporin family and has channel activity and water channel activity. The gene is associated with water transport, one-carbon compound transport, vacuole organization, leaf development, polar cell growth, and homeostasis. It is linked to response to salt and salinity response, as well as regulation of gene expression and response to thirst. The product localizes to the vacuolar membrane, tonoplast, and membrane. Studies of related genes in other species link the family to drought tolerance, chlorophyll content, water absorption by seed, and salt tolerance.
