ABSTRACT
Horsegram (Macrotyloma uniflorum [Lam.] Verdc.) is an underutilized warm-season diploid legume (2n = 20, 22). Because of its ability to grow under water-deficient and marginal soil conditions, horsegram is a preferred choice in the era of global climate change. In recognition of its potential as a crop species, we generated and analyzed a draft genome sequence for a horsegram variety, HPK-4. Ten chromosome-scale pseudomolecules were created by aligning Illumina scaffold sequences onto a linkage map. The total length of the ten pseudomolecules was 259.2 Mbp, covering 89% of the total length of the assembled sequences. A total of 36,105 genes were predicted on the assembled sequences. Diversity analysis of 89 horsegram accessions by dd-RAD-Seq identified 277 single nucleotide polymorphisms (SNPs), suggesting narrow genetic diversity among the horsegram accessions. This is the first attempt to generate a draft genome sequence of horsegram and will provide a reference for sequence-based analysis of horsegram germplasm.
