In a new bioRxiv preprint, scientists from Johns Hopkins present a major step forward in accuracy and completeness for the wheat genome. Their new assembly, generated largely from PacBio data, demonstrates the importance of using long, highly-accurate reads for resolving extremely complex, repetitive genomes. “The first near-complete assembly of the hexaploid bread wheat genome, Triticum aestivum,” comes from lead author Aleksey Zimin, senior author Steven Salzberg, and collaborators. In launching this project, the team aimed to overcome a…
