AAP1 — Brassica napus

Summary

BnAAP1 (DARMORV10_A01P28500.1) on chromosome A01 of oilseed rape encodes an amino acid permease with transmembrane transporter activity for L-serine, L-proline, L-alanine, L-glutamine, L-glutamate and neutral amino acids. The protein localises to the plasma membrane and is associated with amino acid import, phloem loading, meristem and flower development, leaf development and senescence, seed development, cytokinin metabolism, and response to nematodes. The gene has been linked to seed size, seed weight, seed protein content, seed yield, forage yield, rubisco content, amino acid content, nitrogen use efficiency, nitrogen content, proline accumulation, and nematode resistance. Related genes in other species are linked to salt tolerance and calcium-enhanced proline toxicity.
