Status Netherlands: NRGene and Wageningen University Partner to Create Multi-Genome Map of Potato

NRGene, the worldwide leader in genomic assembly and analysis, is working with a team of researchers from Wageningen University & Research (WUR) in the Netherlands and leading commercial partners to create multi-genome mapping of commercial food potatoes.

Potatoes are the fourth most consumed food crop in the world, reaching 11 billion in global trade. The potato genome is complex. It’s an auto-tetraploid, which means that each potato cell contains four nearly identical copies of each chromosome and gene, making the assembly and phasing of the four copies extremely difficult for traditional technologies.

NRGene has completed the phased assembly of three commercial potato varieties. The assembly is built of scaffolds with an N50 of 1.19 Mbp, less than 0.89% unfilled gaps, and BUSCO results of 96.25%, 86% of which are found in more than one copy
