AAP1 — Brassica oleracea var. botrytis

Summary

BoAAP1 (also known as BoNAT2) on cauliflower chromosome 1 encodes a transmembrane amino acid permease with L-serine, L-proline, L-alanine, L-glutamine, L-glutamate and neutral amino acid transmembrane transporter activity. It is localised to the plasma membrane and is associated with amino acid import, including L-alanine transport and L-glutamate import into cells. The gene has been associated with seed weight, seed protein content, seed yield, nitrogen use efficiency, nitrogen content, proline accumulation, storage protein synthesis, amino acid transport and uptake, and nematode resistance. Related genes in other species link the family to salt tolerance and calcium-enhanced proline toxicity.
