Affymetrix, Inc. has launched the Axiom strawberry genotyping array , designed to enable high-resolution genotyping and fully-automated data analysis of the octoploid strawberry genome.
The 90,000 SNP array will enable complex trait research and set the stage for multi-trait, marker-assisted breeding of the cultivated garden strawberry - an allo-octoploid with a chromosome number of 2n=8x=56.
While there are other genotyping technologies available to scan genomes of agricultural species at high resolution, most have been designed for diploids.
Using Affymetrix’s advanced bioinformatics and design strategy, Axiom Genotyping Solution provides genome-wide genotyping and accurately calls the genotypes of both diploid and polyploid species.
The technology has already been successfully applied to complex genomes such as maize, rose, wheat, trout, and salmon.
Axiom Strawberry Genotyping Array was designed through a public-private partnership between Affymetrix and the International RosBREED SNP Consortium (IRSC).
The RosBREED team partnered with the Affymetrix array design and bioinformatics teams to devise SNP selection and data analysis strategies.
RosBREED announced the availability of the array through its September 2013 newsletter. Preliminary results from the array were presented at the 2013 annual conference of the American Society for Horticultural Science.
“Genotyping the octoploid strawberry genome demonstrates the power and precision of the Axiom Genotyping platform to type genetic variants within complex genomes,” said Andy Last, executive vice president of the Genetic Analysis Business Unit at Affymetrix.
“The array design process and updates to the automated analysis software used with Axiom Strawberry Genotyping Array are significant milestones for our platform because they enable the worldwide plant and animal genotyping community to leverage the Axiom myDesign customisation process and analysis software to genotype even more species of interest.”
Axiom Strawberry Genotyping Array will complement the catalogue of Axiom Agrigenomics Genotyping Arrays that are available for multiple species, including bovine, chicken, and buffalo.
These products have been used for genome-wide association studies, quantitative trait locus mapping, genome mapping, and breeding activities that make use of marker-assisted selection and genomic selection.
As scientists make progress in decoding genomes of various plants, animals, and fish using next-generation sequencing platforms, they can advance their research and commercial objectives by translating those discoveries to routine applications on the Axiom Genotyping platform.
