Linkage mapping results for N2 and HW resistance to N. parisii infection.

(A) Logarithm of the odds (LOD) ratios for linkage between pathogen load and genomic position in RIAILs. Dotted line is the 5% genome-wide significance threshold obtained after 10,000 permutations of the phenotype data. Red triangles indicate rami loci. (B) Pathogen load measured by qRT-PCR in parental strains and near-isogenic lines (NILs) bearing the QTL intervals for chromosome II and/or chromosome V. Graphed are the mean values with error bars as SD from at least eight replicates over four experiments. Chromosomes are drawn red for N2 genotype and blue for HW genotype. The written genotype describes markers at the indicated QTL.
