Narrow-leafed lupin (Lupinus angustifolius) is an important grain legume crop for some parts of the world like Australia and parts of Northern Europe where it can form an important part of sustainable farming systems, reducing the need for nitrogenous fertiliser, providing valuable disease breaks and boosting cereal yields. Through the genome revolution and in particular rapid advances in next-generation sequencing technologies, there are new powerful tools available to help with gene discovery and to rapidly accelerate pre-breeding and breeding programmes for narrow-leafed lupin and other lupin crops. This chapter provides an overview of the genomic resources available for narrow-leafed lupin with a focus on the current reference genome which underpins many of the other resources. The cultivar Tanjil was chosen as the reference accession for narrow-leafed lupin and a short-read sequencing approach coupled with BAC-end sequence data was used to assemble the first comprehensive reference genome for the species. This genome assembly captured ~610 Mb of the estimated 921 Mb genome of narrow-leafed lupin with an annotated gene set of 33,076 genes. The narrow-leafed lupin reference genome has provided valuable insight into narrow-leafed lupin evolution and important information on some of its key plant-microbe interactions. The chapter also touches on some of the genomic resources that are in the pipeline in lupins and describes the lupin genome portal, a web-based resource that houses genomic and related information for narrow-leafed lupin.
Narrow-leafed lupin genomic work in the authors group has been supported by Grains Research and Development Corporation (GRDC), CSIRO, Curtin University and the University of Western Australia.
