PIP2 — Brassica oleracea

Summary

BoPIP2 (BOLC102_C03P025420.1) on cabbage chromosome 3 encodes an aquaporin family protein with water channel activity, phospholipase D activity, and protein kinase activity. It is associated with phosphatidic acid metabolism, glucosinolate transport and breakdown, hydrogen peroxide membrane transport, response to desiccation, brassinosteroid response, regulation of stomatal closure, and circadian regulation of gene expression. The gene is linked to numerous agronomic traits including photosynthetic rate, stomatal resistance, root hair length, flowering time, vegetative growth, and responses to salt, drought, freezing, aluminum, and low temperature stress. It has been connected to disease tolerance, including downy mildew and powdery mildew responses, as well as bacterial resistance and basal defense. Localization evidence places the product at the plasma membrane, plasmodesmata, endoplasmic reticulum, Golgi, and plant-type vacuole.
