Draft genome sequence of pigeonpea (Cajanus cajan), an orphan legume crop of resource-poor farmers

Pigeonpea is an important protein source in many developing countries, but limited genetic resources have constrained its improvement. The draft genome sequence of pigeonpea, the first for a nonindustrial crop and for a grain legume, should facilitate molecular breeding efforts to improve yields for subsistence farmers. Pigeonpea is an important legume food crop grown primarily by smallholder farmers in many semi-arid tropical regions of the world. We used the Illumina next-generation sequencing platform to generate 237.2 Gb of sequence, which along with Sanger-based bacterial artificial chromosome end sequences and a genetic map, we assembled into scaffolds representing 72.7% (605.78 Mb) of the 833.07 Mb…
