PIP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0551510 (symbol PIP1, HvPIP1) on barley chromosome 6H encodes an aquaporin-like protein with water channel activity, belonging to the major intrinsic protein (MIP) family. It is associated with water transport, protein homo- and heterotetramerization, regulation of phosphorylation, leaf development, defense response, homeostasis, syngamy, and NO storage. The protein localizes to the membrane, plasmalemma, and macromolecular complexes. HvPIP1 is associated with leaf water potential, shoot fresh weight, transpiration rate, and stomatal resistance. Related genes in other species are linked to similar water transport and stress-related processes.
