PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0537740 (HvPIP1) on barley chromosome 5H encodes a protein with MIP and aquaporin-transporter domains. The product is annotated with phospholipase D activity, peptide binding and receptor activity, and kinase activity, and is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and circadian regulation of gene expression. HvPIP1 has been linked to leaf water potential, stomatal resistance and opening, photosynthetic rate, root hair length, lateral root length, shoot fresh weight, germination rate, flowering time, seed growth, and responses to drought, cold, cadmium, aluminum, low humidity, desiccation, bacterial disease, powdery mildew, and downy mildew. It localises to the plasma membrane, cell wall, vacuole, chloroplast envelope, and plasmodesmata.
