Physical maps of the potato chromosomes I to VI (pseudomolecules v4.03).

<p>Maps ‘a’ show to the left of the central bar (representing the chromosome) the positions of markers that were previously shown to be linked with <i>P</i>. <i>infestans</i> QRL in potato and the highly syntenic tomato (<i>Solanum lycopersicum</i>). Markers linked to <i>P</i>. <i>infestans</i> QRL in tomato are underlined (for physical positions and references see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.s008" target="_blank">S8 File</a>). The candidate loci tested for association with MCR, rAUDPC and PM in the PIN184 population previously [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.ref005" target="_blank">5</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.ref011" target="_blank">11</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.ref024" target="_blank">24</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.ref034" target="_blank">34</a>] and in this paper (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.s003" target="_blank">S3 File</a>) are shown to the right of maps ‘a’. Nine major genes for resistance to <i>P</i>. <i>infestans</i> (<i>R1</i>, <i>R2</i>, <i>R3</i>, <i>Rpi-blb1/RB</i>, <i>Rpi-blb2</i>, <i>Rpi-blb3</i>, <i>Rpi-vnt1</i>, <i>Rpi-abpt</i>, <i>Ph-3</i>) and the <i>StCDF1</i> locus controlling day length dependent tuberization are also included in maps ‘a’ (physical positions and references in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.s008" target="_blank">S8 File</a>). Loci harboring DNA variants associated with MCR, rAUDPC and/or PM are labelled with green, blue and red stars, respectively. Maps ‘b’ show the positions of the SolCAP SNPs that were associated with MCR (green bars), rAUDPC (blue bars) and PM (red bars) in the PIN184 population, on the left according to the association model without correction for population structure (model S) and on the right according to the association models correcting for population structure with different methods (K₁, K₂ and K₂Q, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#sec012" target="_blank">Materials and Methods</a>). SolCAP SNPs associated with at least one trait with p < 10⁻⁴ were included. The length of the horizontal bars is proportional to the p-value. The dotted vertical lines indicate–Log10(P) = 4. Maps ‘c’ show on the right (blue dots) the positions of candidate genes that (i) harbor SNPs with different allele frequencies in the R8 and S8 genotype pools with high (R) and low (S) resistance to late blight (Materials and Methods), and (ii) had differential transcript levels between three genotype pools with different MCR levels in SuperSAGE analysis [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.ref023" target="_blank">23</a>]. The green dots on the left of maps ‘c’ show the positions of candidate genes that (i) harbor SNPs with different allele frequencies in the R8 and S8 genotype pools, (ii) had differential transcript levels between the three genotype pools with different MCR levels in SuperSAGE, and (iii) were up or down regulated upon infection with <i>P</i>. <i>infestans</i> in SuperSAGE (for details see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0156254#pone.0156254.s007" target="_blank">S7 File</a>). Maps ‘d’ show the distribution of 42,688 SNPs with different allele frequencies in the R8 and S8 genotype pools (q < 0.01) on the potato pseudomolecules. The scale [number of SNPs per Mbp] is shown horizontally on top of each chromosome. SNP density peaks which overlapped with genomic segments harboring QTL for MCR or PM based on GWAS are indicated by numbers 1 to 8.</p
