Abstract

Narrow-leafed lupin (NLL; Lupinus angustifolius) is a grain legume crop that is recognised as a human health food. However, the crop harbours undesirable traits which limit grain quality. The research used NLL genomic and transcriptomic resources to investigate the genetic factors underlying important traits for grain quality, focusing on the toxic quinolizidine alkaloids that accumulate in the grain. This work contributes substantially to the understanding of alkaloid biosynthesis in NLL and proposes gene targets of value for the reduction of grain alkaloid content. This serves to enhance the value of NLL grain and encourage its use in sustainable agricultural practices.
