A transcriptome-SNP-derived linkage map of Apios americana (potato bean) provides insights about genome re-organization and synteny conservation in the phaseoloid legumes.

We report a linkage map for Apios americana and describe synteny with selected warm-season legumes. A translocation event in common bean and soybean is confirmed against Apios and Vigna species. Apios (Apios americana; "apios"), a tuberous perennial legume in the Phaseoleae tribe, was widely used as a food by Native Americans.

Genomics-assisted characterization of a breeding collection of Apios americana, an edible tuberous legume.

For species with potential as new crops, rapid improvement may be facilitated by new genomic methods. Apios (Apios americana Medik.), once a staple food source of Native American Indians, produces protein-rich tubers, tolerates a wide range of soils, and symbiotically fixes nitrogen.
