AT2S1 — Brassica napus

Summary

BnAT2S1 (AT2S1, SESA1) on chromosome A01 of oilseed rape (Brassica napus) encodes a napin/2S seed storage protein belonging to the bifunctional inhibitor/LTP/seed storage superfamily and is annotated with nutrient reservoir activity. The gene is associated with seed storage protein accumulation, seed protein content, seed weight, seed size, raffinose content, amino acid content, and protein content. It is associated with biological processes including protein storage, nitrogen homeostasis, regulation of lipid metabolism, phytate biosynthesis, carotene anabolism, and sinapate ester anabolism, and localises to the extracellular region. Studies of related genes in other species connect the family to drought tolerance and root morphology traits.
