TIP2 — Brassica oleracea

Summary

BoTIP2 (BOLC102_C07P039860.1) on cabbage chromosome 7 encodes an aquaporin family protein with water channel activity, localised to the tonoplast, vacuolar membrane, Golgi and ER. The gene is associated with water transport, hydrogen peroxide membrane transport, glucosinolate transport, and porphyrin-containing compound metabolic processes. It is linked to vacuole organisation, pollen exine formation, anther development, microsporogenesis, meiosis, organogenesis, leaf development, polar cell growth, and osmotic and salt responses. Associations with agronomic traits include drought tolerance, salt tolerance, stomatal resistance, seed growth and development, oleic acid content, triacylglycerol content, seed fatty acid content, thermotolerance, and plant stress response. Studies of related genes in other species connect them to hydrogen peroxide transport, ABA sensitivity, drought response, seed oil content, and lipid droplet accumulation.
