PIP2 — Brassica oleracea

Summary

BoPIP2 (BOLC102_C03P025410.1) on cabbage chromosome 3 encodes a member of the aquaporin family, possessing water channel activity, phospholipase D activity, and protein kinase activity. The gene is associated with phosphatidic acid metabolism, glucosinolate transport and breakdown, hydrogen peroxide membrane transport, and regulation of stomatal closure. It is linked to responses to desiccation, brassinosteroid, aluminum, and circadian regulation of gene expression. The protein localizes to the plasma membrane, plasmodesmata, plant-type vacuole, and ER. BoPIP2 is associated with numerous agronomic traits including photosynthetic rate, stomatal resistance, root hair length, flowering time, cadmium concentration, and responses to salt, drought, freezing, and oxidative stress. It is also linked to disease tolerance, including downy mildew and bacterial resistance, as well as cell elongation and vegetative growth traits.
