PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0188290 (HvPIP1) on barley chromosome 2H encodes a protein with aquaporin-like and MIP 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 leaf water potential, photosynthetic rate, stomatal resistance and opening, germination rate, flowering time, root hair length, lateral root length, shoot fresh weight, and responses to drought, cold, aluminum, cadmium, and bacterial and fungal diseases. Localisation evidence connects the product to the plasma membrane, cell wall, vacuole, chloroplast envelope, and plasmodesmata. Studies of related genes in other species link the family to water transport, root water uptake, stomatal closure, and drought stress tolerance.
