PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0182400 (HvPIP1) on barley chromosome 2H encodes a protein with aquaporin and aquaporin-like domains, and is annotated with channel activity and phospholipase D activity. The gene is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and regulation of phosphorylation. It is linked to drought stress tolerance, cold stress response, photosynthetic rate, stomatal opening, leaf water potential, root hair length, lateral root length, shoot fresh weight, germination rate, flowering time, and disease responses to powdery mildew and Fusarium. Localization evidence connects the product to the plasma membrane, plant-type cell wall, vacuole, and chloroplast envelope. Studies of related genes in other species link the family to water transport, root water uptake, and transpiration rate.
