Abstract excerpt

Wild Arachis species exhibit abundant genetic diversity for peanut improvement. However, the evolutionary history of their genomes is unclear. Here, through comparative oligopainting, we establish a one-to-one correspondence between microscopically observed chromosomes and sequenced pseudomolecules of Arachis duranensis, A. ipaensis, and cultivated peanut, and determine the 10 homoeologous groups (Hgs) of the A,...
