PIP1 — Nicotiana attenuata

Summary

A4A49_07093 (PIP1) on coyote tobacco (Nicotiana attenuata) chromosome 1 encodes an aquaporin-like protein with water channel activity and channel activity. It is associated with water and gas transport, oxygen metabolism, pyruvate metabolism, the TCA cycle, and protein heterotetramerization. The gene is linked to primary root and root hair cell development, as well as responses to salt, cold, osmotic stress, and ABA signaling. It is linked to carbon isotope discrimination. The product localizes to the membrane, plasmalemma, ER, and cytosol. Studies of related genes in other species further connect this family to water transport and stress responses.
