SNP genotyping

Bulk samples of dried leaves or kernels from up to eight D₁ plants derived from the same D₀, were used for DNA extraction using the cetyl trimethylammonium bromide (CTAB) procedure. DNA samples were adjusted to 50 to 70 ng/?l and 200 ng per sample were used for genotyping. DH line purity and integrity was first checked using a custom 96plex VeraCode assay (Illumina ® , San Diego, CA, USA) with genome-wide SNP markers to ensure that the lines carried only one of the parental alleles at each SNP, that they did not carry alleles of the inducer line and that they were derived from true F₁ plants. For a subset of DH lines, 13 proprietary SNP markers assayed with the KASP™ technology (LGC Genomics, Berlin, Germany) were used for testing line purity and integrity. True DH lines were then used for genotyping with the Illumina ® MaizeSNP50 BeadChip on an Illumina ® iScan platform. Array hybridization and raw data processing were performed according to manufacturer’s instructions (Illumina ® ). Raw data were analyzed in Illumina ® ‘s Genome Studio software version v2011 (Illumina ® ) using an improved version of the public cluster file (MaizeSNP50_B.egt, ). SNP data were filtered based on the GTscore using a threshold of 0.7. Heterozygous SNPs were set to missing values (NA) and only markers with a minor allele frequency >0.1 per population were used for mapping. For each population, the allele of the central line was coded as the ‘A’ allele, and the allele of the founder line was coded as ‘B’ allele (Additional file 4). Raw genotyping data of parents and DH lines are available at NCBI Gene Expression Omnibus as dataset GSE50558 .

Data regarding adult genetic diversity

Genetic assortment between adult outlines was examined that have genome-large SNP markers from the dominating complement study, class study, by a great pairwise genome test to own polymorphism within parents of any populace. To have facts, discover Extra file 8.

Genetic chart design

Hereditary maps was constructed for every single private inhabitants due to the fact explained earlier having fun with CarthaGene entitled from personalized Roentgen programs. In the first step, statistically powerful scaffold charts was in fact built with marker ranges from at the the very least 10 cM. In a moment action, ework maps that https://datingranking.net/pl/livejasmin-recenzja/ has as numerous indicators you could, while maintaining a good LOD rating >3.0 with the robustness out-of marker purchases. Eventually, the complete maps was received by keeping of extra indicators playing with bin-mapping . CentiMorgan (cM) distances was computed having fun with Haldane’s mapping setting . Individual hereditary charts and you may genotypic data useful for framework of maps (A lot more file cuatro) was placed on MaizeGDB beneath the venture phrase CORNFED .

Bodily chart coordinates out of SNPs

Chromosome and you will standing tasks from SNPs of MaizeSNP50 BeadChip provided by the product manufacturer (Illumina ® , Hillcrest, Ca, USA), derive from the brand new B73 AGPv1 system with many different markers devoid of an effective chromosome and/otherwise status recommendations. I therefore performed another type of mapping of one’s SNPs into the B73 AGPv2 system using BWA . This new assignments were utilized for everybody analyses amongst the actual mapping guidance. Tasks appear in A lot more file cuatro.

Provided an excellent chromosome together with related genetic chart of an individual populace, i computed the brand new marker ranking to your B73 assembly. Because of these physical and genetic positions, i developed an initial Marey chart containing most of the syntenic indicators. This Marey chart is actually smoothed using cubic spline interpolations , generating a ‘bare’ Marey chart which had been obligated to getting monotonic. Following regions where mapping information try not having (such as for instance, avenues IBD in the parents) had been masked, generating ‘masked’ Marey charts (More document nine). New outlined processes try said inside Additional document 8.
