Draft Genomes of Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri [PDF]

Genome Biology and Evolution, 2020
Abstract Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri are agronomically important weed species. Here, we present the most contiguous draft assemblies of these three species to date. We utilized a combination of Pacific Biosciences long-read sequencing and chromatin contact mapping information to assemble and order
