PIP2 — Camelina sativa

Summary

CSA05G016690 (CsPIP2) encodes a protein from the aquaporin family, possessing water channel activity, phospholipase D activity, and protein kinase activity. It is associated with membrane transport, including hydrogen peroxide and arsenite import, and with responses to desiccation, brassinosteroid, aluminum, and circadian regulation. The gene is linked to numerous agronomically important traits: photosynthetic rate, stomatal closure, root hair length, flowering time, and tolerance to drought, salt, freezing, and oxidative stress. It has also been connected to disease responses, including downy mildew and powdery mildew resistance, as well as to phosphorus response, cadmium concentration, and cellulose content. Localization evidence places the product at the plasma membrane, plasmodesmata, endoplasmic reticulum, Golgi, and vacuole. Studies of related genes in other species link the PIP2 family to water transport, stomatal movement, root hydraulic conductivity, and pathogen resistance.
