QTL and Fine-mapping data.

README) Column descriptions for following tables QTL phenotypes) Attachment test results (Pasteuria ramosa P21 hindgut attachment) for all Daphnia magna clones from the QTL panel. Red and blue shading correspond to susceptible (attachment positive) and resistant (attachment negative) phenotypes, respectively. QTL SNP map) QTL mapping data containing clone names, attachment phenotype, (1 = susceptible, 0 = resistant), and genetic markers with corresponding genotypes (AA = matching resistant parent, BB = matching susceptible parent, AB = heterozygous). Infection experiment) Attachment and infection results for 40 Daphnia magna clones from the QTL panel. Thirty individuals from each clone were exposed to spores from Pasteuria ramosa genotype P21 and assessed for disease symptoms after five weeks. Marker primers) Primer information for all size-polymorphic (microsatellite) and SNP markers used for fine mapping. Finemap microsat) Fine-mapping results from size-polymorphic (microsatellite) markers. A subset of clones from the QTL panel was selected for genotyping at eight markers within the QTL region (See S1 Methods for additional description of fine-mapping procedures). Red cells (B) indicate a haplotype matching the susceptible parent Xinb3, dark blue cells (A) indicate a match to the resistant parent (Iinb1), and light blue cells (H) indicate heterozygotes. Clones 177 and 693 (delimited) identify the limits of this fine-mapping effort at markers D42 and U1, respectively. Finemap Sanger) Fine-mapping results from SNP markers. Clones 177 and 693 were selected for further fine mapping at 13 additional markers. Recombination breakpoints were localized within markers U0_55 and D16_9.
