First high-quality reference genome of Amphicarpaea edgeworthii

Abstract

Amphicarpaea edgeworthii, an annual twining herb, is a widely distributed species and an ideal model for studying complex flowering types and evolutionary mechanisms of species. Herein, we generated a high-quality assembly of A. edgeworthii by using a combination of PacBio, 10x Genomics libraries, and Hi-C mapping technologies. The final 11 chromosome-level scaffolds covered 90.61% of the estimated genome (343.78 Mb), which is the first chromosome-scale assembled genome of an amphicarpic plant. These data will be beneficial for the discovery of genes that control major agronomic traits, spur genetic improvement of and functional genetic studies in legumes, and supply comparative genetic resources for other amphicarpic plants.
