Information Will Significantly Advance Breeding Efforts and Lead to Improved Animal Food Supply
Ness Ziona, Israel – August 29, 2017 – NRGene, the worldwide leader in genomic assembly and analysis, has provided scientists with the complete genome of Italian ryegrass (Lolium multiflorum Lam.), one of the most important forage crops in temperate regions worldwide.
“With the complete genome, we’ll be able to more fully analyze the traits to increase the yield and nutritional quality when used for animal feed,” says Dr. Bruno Studer of ETH Zurich’s department of Environmental Systems Science. “We have decided to focus our research on biologically relevant traits rather than resource establishment that may take decades. With NRGene, we received comprehensive results within weeks, accelerating our entire research pipeline.”
The genome itself is exceptionally complex and highly repetitive. It is diploid and heterozygote, meaning each gene has two nearly identical copies. To provide a complete and accurate genome view it was essential to phase the two copies of the genome. This is not a trivial task and was previously impossible. It could only be accomplished only with DeNovoMAGICTM3.0.
NRGene’s DeNovoMAGICTM 3.0 used Illumina reads and big data analytics to deliver the complete, phased genome in less than eight weeks. The complete phased assembly is 4.5 Gbp and an N50 of over 3 million bp.
“Constructing phased genomes for heterozygote crops is exceptionally challenging, and we are pleased to provide the ryegrass community with a top quality one,” says Dr. Gil Ronen, NRGene CEO. “The genome data will immediately be used to support the diverse genetic studies and breeding applications of this important crop.”
NRGene is a genomic big data company developing cutting-edge software and algorithms to reveal the complexity and diversity of crop plants, animals, and aquatic organisms for supporting the most advanced and sophisticated breeding programs. NRGene tools have already been employed by some of the leading seed companies worldwide as well as the most influential research teams in academia. www.nrgene.com.
