PIP1 — Nicotiana attenuata

Summary

A4A49_22343 (PIP1) in coyote tobacco (Nicotiana attenuata) encodes a protein with aquaporin and MIP domains and water channel activity. The gene is associated with water and gas transport, including oxygen transport, as well as pyruvate metabolism, the TCA cycle, and responses to salt, cold, and osmotic stress. It is linked to ABA signaling, primary root and root hair cell development, and protein heterotetramerization and homotetramerization. The product localizes to the membrane, plasmalemma, ER, and cytosol. PIP1 is also associated with carbon isotope discrimination. Related genes in other species link the family to water transport and stress responses.
