PIP2 — Brassica oleracea

Summary

BoPIP2 (BOLC102_C04P011430.1_BOLC102_V1) on cabbage chromosome 4 encodes an aquaporin family protein with water channel activity, phospholipase D activity, and protein kinase activity. It is associated with glucosinolate transport and breakdown, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and regulation of stomatal closure. The gene has been linked to responses to desiccation, brassinosteroid, aluminum, and circadian regulation of gene expression. It localizes to the plasma membrane, plasmodesmata, endoplasmic reticulum, Golgi, and plant-type vacuole. BoPIP2 is linked to numerous agronomic traits including photosynthetic rate, stomatal resistance, root hair length, flowering time, vegetative growth time, and responses to salt, drought, freezing, and oxidative stress. It has also been associated with disease tolerance, including downy mildew and bacterial resistance, as well as cell elongation and root morphology traits.
