PIP2 — Brassica oleracea var. botrytis

Summary

BoPIP2, encoded by the gene BOLND125_C08P040090.1 on cauliflower chromosome 8, is a member of the aquaporin family, possessing water channel activity and phospholipase D activity. It is associated with a wide range of biological processes, including response to desiccation, regulation of stomatal closure, circadian regulation of gene expression, and responses to brassinosteroid, salicylate, bacteria, and aluminum. The gene is linked to numerous agronomically relevant traits such as photosynthetic rate, root hair length, flowering time, disease tolerance, and responses to salt, drought, and low temperature stress. It localizes to the plasma membrane, plasmodesmata, and plant-type vacuole. Studies of related genes in other species link the family to water transport, stomatal movement, and stress tolerance.
