PIP2 — Camelina sativa

Summary

CsPIP2 (CSA06G039860) on chromosome 6 of Camelina sativa encodes an aquaporin family protein with water channel activity, phospholipase D activity, and protein kinase activity. It is associated with membrane transport, including hydrogen peroxide membrane transport, and localizes to the plasma membrane, plasmodesmata, and vacuole. The gene is linked to response to desiccation, response to brassinosteroid, response to aluminum, and antiviral response, as well as regulation of stomatal closure and circadian regulation of gene expression. Agronomically, CsPIP2 is associated with photosynthetic rate, root hair length, flowering time, salt and drought tolerance, disease resistance, and cell elongation. Studies of related genes in other species link the family to water flux, stomatal movement, root hydraulic conductivity, and stress tolerance.
