PIP1 — Zea mays

Summary

ZmPIP1 (ZM00001EB247760) on maize chromosome 5 encodes an aquaporin PIP2-4 protein with channel activity and phospholipase D activity, among other molecular functions. It is associated with carbon dioxide and urea transport, C4 photosynthesis, nitrate import, hydrogen peroxide membrane transport, and regulation of hormone metabolism. The gene has been linked to numerous agronomic traits including root moisture content, leaf relative water content, leaf water potential, turgor pressure, drought sensitivity, aluminum tolerance, cadmium concentration, sodium uptake, nitrate uptake, phosphorus response, leaf elongation rate, leaf length, root fresh and dry weight, shoot fresh weight, lateral root length, root hair length, vegetative growth time, oleic acid content, and quantum yield. It is also connected to responses to bacterial disease, cucurbit downy mildew, wheat powdery mildew, and ethylene and brassinosteroid sensitivity. The protein localizes to the plasma membrane region, plant-type cell wall, chloroplast envelope, and other cellular compartments.
