UC Davis Buys Irys DNA Mapping System from BioNano Genomics

NEW YORK (GenomeWeb News) – The University of California, Davis, has purchased an Irys single-molecule DNA mapping system from BioNano Genomics, the company said today.

Among other projects, researchers at UC Davis are planning to use the Irys system to help with the assembly of the genome of a progenitor of bread wheat, Aegilops tauschii.

About a year ago, scientists at the US Department of Agriculture, UC Davis, the University of California San Francisco, and BioNano Genomics published a collaborative study in PLOS One in which they used a BioNano map to assemble a 2.1-megabase highly repetitive region in the A. tauschii genome.

"Based on the success of that collaboration, we have decided to acquire our own Irys system, and we will build upon that research to create an accurate draft of the entire D genome sequence [of A. tauschii]," said Ming-Chen Luo, a research geneticist in the department of plant sciences at UC Davis, in a statement.

That information can be used to predict gene locations and to help with sequencing and assembling the genomes of wheat and its relatives, he said.

BioNano Genomics launched the Irys platform in late 2012 and expanded its throughput last year with the IrysChip V2 to support larger genomes.

The company focuses on mapping human genomes, assembling genomes that do not have a reference, and analyzing complex regions in plant genomes.
