PIP2-1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_9G207950, designated PIP2-1 on sugar beet chromosome 9, encodes a protein belonging to the aquaporin family, with water channel activity. The gene is associated with water transport, protein homo- and heterotetramerization, pH reduction, and nitric oxide storage. Its product localizes to the membrane and plasmalemma. PIP2-1 is associated with pathways for arsenite import, arsenic uptake and detoxification, and responses to heavy metals and abiotic stimuli. The gene has also been linked to nitrogen content.
