PIP2 — Camelina sativa

Summary

CsPIP2 (CSA06G039850) encodes an aquaporin family protein with channel activity, water channel activity, and phospholipase D activity, and is associated with phosphatidic acid metabolism, hydrogen peroxide membrane transport, and membrane transport. This Camelina sativa gene on chromosome 6 is linked to responses to desiccation, brassinosteroid, aluminum, and abscisic acid signaling, as well as regulation of stomatal closure, circadian regulation of gene expression, and antiviral response. It localizes to the plasma membrane, plasmodesmata, endoplasmic reticulum, Golgi, and vacuole. CsPIP2 is associated with traits including photosynthetic rate, root hair length, flowering time, cellulose content, cadmium concentration, salt and drought tolerance, disease resistance, and freezing tolerance. Studies of related genes in other species link the family to dehydration stress tolerance, water transport, stomatal movement, and pathogen response.
