Genetic architectures of resistance identified in the round-robin crosses.

<p>Genome-wide LOD scores for (<b>A</b>) sodium chloride and (<b>B</b>) caffeine experiments are plotted jointly for the 12 Round Robin crosses to illustrate the how QTL are shared among the different crosses (see <a href="" target="_blank">S4 Fig</a>. for individual plots). The large effects of the multi allelic <i>ENA</i> locus on salt and <i>TOR1</i> on caffeine resistance are readily apparent. At each position the minimum of replicate selections is plotted for each cross. Tick marks on the upper axis indicate peak positions of QTL identified (QTL are listed in <a href="" target="_blank">S4 Table</a>).</p>
