Plant and Animal Genotyping
From Genomic Variants to Physical Traits
Animal and plant genotyping has become a mainstay of modern agricultural research. Illumina microarrays enable high-throughput screening of known genomic markers to inform selection and breeding decisions. Array-based studies can also be used to discover novel associations between SNP (single nucleotide polymorphism) markers and traits or diseases.
Plant and Animal Genotyping Applications
Custom Arrays for Animal and Plant Genotyping
Not every nonhuman organism has been extensively genetically investigated, resulting in an absence of commercial genotyping arrays for certain plant and animal species. We offer custom microarrays that can be designed with all the discovered markers for species of interest, enabling genotyping studies to identify variants associated with desired phenotypic traits. Through ongoing work with major agrigenomics consortia, our technology is being used to identify new, relevant markers in a wide range of species.
Copy Number Variation Studies
A common form of natural diversity, copy number variation (CNV) is also heritable. It appears to play an important role in agrigenomics. CNV differences can correlate to health and production traits, and contribute to phenotypic diversity. In animal and plant genotyping studies, the distribution of high-density probes can be used to identify CNV breakpoints and ultimately accelerate genomic improvements. Studies are ongoing to determine if the impact of CNVs is the result of differences in copy number for key genomic segments, structural modification of the genome, or a combination of both.
Fine Mapping and Candidate Gene Region Genotyping
Microarray-based animal and plant genotyping can be used to create fine map traits and/or test a genotype-phenotype hypothesis. Quantitative trait loci (QTL) analyses can be performed on the results to characterize how differential gene expression might contribute to phenotypic variation.
Whole-Genome Association Studies
Association mapping across an entire animal or plant genome provides insight into the genetic location and architecture of linking traits to species’ adaption (eg, to a wide variety of environmental conditions). The results of these studies support whole-genome selection applications (eg, fingerprinting, net merit, marker-assisted breeding) that enhance the value of commercial crops and herds. Illumina microarrays offer focused content, custom capabilities, and convenient add-on content capabilities.
