PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0596770 (HvPIP1) on barley chromosome 6H encodes an aquaporin-like protein with water channel activity. The gene is associated with water transport, protein heterotetramerization and homotetramerization, regulation of phosphorylation, leaf development, defense response, homeostasis, syngamy, and NO storage. The product localizes to the membrane, plasmalemma, and macromolecular complexes. HvPIP1 has been connected to leaf water potential, shoot fresh weight, transpiration rate, and stomatal resistance. Studies of related genes in other species link this gene family to similar water transport functions.
