Genomic insights into the evolution of Echinochloa species as weed and orphan crop

Echinochloa is an important genus in the grass family as many of them are either problematic weeds or domesticated millets. Here, the authors assemble three polyploidy genomes in this genus using the diploid-assisted scaffolding method DipHic and provide genomic insights into the dual roles of some species as weeds and orphan crops.
