TIP2 — Brassica oleracea

Summary

BoTIP2 (BOLC102_C02P059700.1) on cabbage chromosome 2 encodes a protein with aquaporin domains, and is annotated for channel activity and water channel activity, as well as heme binding and mRNA binding. The gene is associated with water transport, vacuole organization, and localization to the tonoplast and vacuolar membrane. It is linked to glucosinolate transport, hydrogen peroxide membrane transport, and porphyrin-containing compound metabolic process. Agronomically, BoTIP2 is associated with drought tolerance, salt tolerance, stomatal resistance, seed growth and development traits, oleic acid content, and thermotolerance. Additional associations include pollen exine formation, anther development, microsporogenesis, leaf development, and response to salt. Studies of related genes in other species link the family to hydrogen peroxide transport, salt stress sensitivity, drought response, and seed oil content.
