PIP2 — Camelina sativa

Summary

CsPIP2 (CSA05G016680) on Camelina sativa chromosome 5 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 endoplasmic reticulum. The gene is linked to responses to abiotic stresses such as drought, salt, freezing, and aluminum, as well as to brassinosteroid and abscisic acid signaling, stomatal closure regulation, and circadian gene expression. Associations with agronomic traits include photosynthetic rate, root hair length, flowering time, cellulose content, cadmium concentration, and disease responses to downy mildew and powdery mildew. Studies of related genes in other species connect the family to water flux, dehydration tolerance, stomatal movement, and pathogen resistance.
