Footprints of selection in the white lupin genome. (a) Nucleotide diversity (π) comparison between bitter and sweet accessions. A major QTL previously reported for alkaloid accumulation and candidate genes (red) that overlapped with selective sweeps are marked. (b) Candidate gene located on chromosome 3. The gene LaDHDPS is homologue of L. angustifolius gene in the iucundus QTL. Type 5 accessions, originated from Ethiopia, have a SNP in the third exon that causes a mis‐sense variant. (c) Candidate gene located on chromosome 18. The gene LaAT is located inside QTL Pauper and Type 5 accessions and wild accessions GRC5262B have a deletion that causes a disruption in frame of its exon.
