Association of resistance to FOM. In FOM-infected C-T (circle) and r-T (diamond) BC₁ populations, test statistic Z correlates resistance and marker genotype. Lines connect values of linked markers. Marker placement on x-axis corresponds to nucleotide position in TAIR reference sequence of five Arabidopsis chromosomes (CHR1 through CHR5): Ticks are spaced by 20 Megabps. Markers are named CHRx.n, where x and n indicate chromosome and relative marker position, and are labeled above or below the x-axis. Dashed lines indicate the threshold values of Z below which negative values, or above which positive values, are attained with p < 0.05.
