PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0472810 (HvPIP1) on barley chromosome 5H encodes an aquaporin-like protein with channel activity, phospholipase D activity, and peptide receptor activity. It is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and circadian regulation of gene expression. The gene has been linked to numerous agronomic traits including leaf water potential, photosynthetic rate, stomatal resistance and opening, root hair length, lateral root length, shoot fresh weight, germination rate, flowering time, and responses to drought, cold, aluminum, and bacterial and fungal diseases. It is also connected to sodium uptake, cadmium concentration, oleic acid content, and brassinosteroid and ethylene sensitivity. Localization evidence places the product at the plasma membrane, cell wall, chloroplast envelope, and plant-type vacuole.
