Donald Danforth Plant Science Center, NRGene Assemble Second Maize Reference GenomeJanuary 11, 2017
Donald Danforth Plant Science Center and NRGene, in collaboration with a global team of researchers have announced the accurate assembly of the W22 maize reference genome. According to the team, the second version of W22 has reached a scaffold N50 of 35.5 MB with less than 2% unfilled sequence gaps.
Dr. Kelly Dawe of the University of Georgia provided an independent assessment of the W22 genome map using next-generation mapping (NGM) with BioNano's Irys® system. The Irys optical mapping system produced a long-range map of the genome, which can be used to correct or enhance a genome sequence assembly.
Dr. Dawe said, "99.4% of the scaffolds were collinear with our BioNano genome map, indicating that NRGene's DeNovoMAGIC3.0 has generated a very high quality reference assembly." By combining the BioNano data with NRGene's assembly, Dr. Dawe was also able to improve the N50 scaffold size to 75 MB.
