Description
Unit Size: 1 plate
• Array was designed by the University of California, Davis Strawberry Breeding Program in collaboration with Affymetrix Expert Design Program (Hardigan et al 2020)
• The array offers genome-wide coverage of polymorphic SNPs across the cultivated and wild octoploid strawberry species
• The Axiom FanaSNP Strawberry 50K Genotyping Array is also available in 384-HT format (Cat. Number 551041)Array Content
• Comprehensive content850,000 SNPs subgenome specific SNPs from diverse octoploid strawberry accessions from around the globeCollectively, 446,644 of 850,000 marker probes produced QC-passing polymorphic SNP genotype clusters showing disomic (allopolyploid) segregationThe complete set of 446,644 validated probes is made available for public use
• Production scale array also designThe most performant set of 49,483 SNPs was tested and validated for production activities5,809 SNPs from the iStraw 35K array were maintained for connectivity to previous platforms
• Tied to multiple reference genomesSNP positions ascertained by WGS alignment to the `Camarosa` v1 reference genome (Edger et al 2019) and have since been updated to the `UCD Royal Royce` (FaRR1) reference genome (Hardigan et al 2022)
• Global represented and validatedVariants were discovered by WGS resequencing of 47x ananassa,24F. chiloensis,and 22F. virginianaindividualsSubgenome-specific marker performance variants were validated in a genetically diverse sample of 384 octoploid strawberry accessionsApplications
