SNP genotypic data from American pika in North Cascades National Park

Excel file including genotypes at 9825 SNPs for 67 American pika sampled in North Cascades National Park, Washington, USA. The first column is contig name. The second column is SNP position within the contig. Every two columns after is an individual. Each row is a locus. Sample names include the transect identifier (PP=Pyramid Peak; TL=Thornton Lake), site name (ex. 1A), and individual number (ex. 20a). Allele calls are as follows: 1=A, 2=C, 3=G, 4=T

Mapping a novel induced mutation.

<p>(A) Southern blot of digested <i>N. crassa</i> genomic DNA with methylation-sensitive <i>Ava</i>II, showing loss of methylation in the AX7 mutant strain, as compared to the parental mutagenized N2977 strain. (B) Polymorphic RAD markers from N32 (red) and N2977 (green) parental strains were mapped along the seven <i>N. crassa</i> linkage groups. Red and green bars above the linkage groups are measures of linkage in the recombinant progeny, indicating the number of tightly linked markers in the local region. (C) A close-up view of linkage group II, showing the locations of confirmative RFLP markers (arrows). (D) RFLP marker confirmation. RFLP markers were designed using polymorphic RAD markers at 2.1 Mb and 3.1 Mb on LGII for <i>N. crassa</i>. The marker at 2.1 Mb confirmed the lack of recombinants in the wild-type pool, while a portion of individuals in the mutant pool have undergone recombination at this location. RFLP analysis at 3.1 Mb showed complete linkage in both wild-type and mutant pools to the methylation-deficient phenotype.</p

RAD marker generation.

<p>(A) Genomic DNA was digested with a restriction enzyme and the P1 adapter was ligated to the fragments. The P1 adapter contains a forward amplification primer site, an Illumina sequencing primer site, and a barcode (colored boxes represent P1 adapters with different barcodes). (B) Adapter-ligated fragments were combined (if multiplexing), sheared and (C) ligated to a second adapter (P2, white boxes). The P2 adapter is a divergent “Y” adapter, containing the reverse complement of the reverse amplification primer site preventing amplification of genomic fragments lacking a P1 adapter. (D) RAD tags, which have a P1 adapter, will be selectively and robustly enriched.</p

Sequenced RAD marker mapping.

<p>(A) A native saltwater stickleback population, Rabbit Slough (RS), have complete lateral plate armor (brackets) while these structures are absent in the derived, freshwater Bear Paw (BP) population. The freshwater fish also have a reduction in pelvic structure (arrow) compared to the oceanic population. These two phenotypes segregate independently in an <i>F₂</i> mapping cross. Using <i>Sbf</i>I (B) or <i>EcoR</i>I (C), we mapped polymorphic RAD markers from RS (red) and BP (green) parental fish along the 21 stickleback linkage groups. The apparent size differences of the linkage groups between (B) and (C) reflect the fact that the <i>EcoR</i>I recognition sequence occurs more frequently than <i>Sbf</i>I. Red and green bars above the linkage groups are measures of lateral plate linkage in the <i>F₂</i> progeny, indicating the number of tightly linked markers in the local region. (D) Sequence reads per barcoded <i>F₂</i> individual used to create (C). Variable numbers of reads were obtained from each of the 96 individuals used in our analysis, reflecting different concentrations of starting DNA template. 68% of individuals had between 50 K and 150 K RAD tags sequenced (∼0.4–1.0× coverage of the ∼150 K tags present in the genome). Only 2 individuals had less than 10,000 reads (red). (E) A close-up of the boxed region from (C) showing recombination breakpoints in six informative low plate <i>F₂</i> fish on LGIV. Black tick marks are 1 Mb apart in physical distance. (F) <i>F₂</i> individuals were repooled <i>in silico</i> based on the pelvic structure phenotype (A, arrow). Linkage was determined as in (B, C), mapping the locus for a reduction in pelvic structure to the end of LGVII.</p
