PIP2 — Brassica napus

Summary

BnPIP2 (DARMORV10_C03P24080.1) on chromosome C03 of oilseed rape encodes an aquaporin family protein with water channel activity, phospholipase D activity, and protein kinase activity. This gene is associated with water transport, stomatal regulation, and responses to desiccation, hypoxia, brassinosteroid, and aluminum stress. It has been linked to traits including photosynthetic rate, leaf water potential, root hair length, flowering time, cadmium concentration, cellulose content, and heterosis. Associations with salt, drought, freezing, and oxidative stress tolerance, as well as disease resistance and susceptibility, have been reported. The gene is also connected to phosphatidic acid metabolism, hydrogen peroxide membrane transport, circadian regulation of gene expression, and systemic acquired resistance. Studies of related genes in other species link the family to water flux, root hydraulic conductivity, stomatal movement, and pathogen response.
