Corrigendum

In the article by M. Christopoulou et al. (G3 Genes|Genomes|Genetics 5: 2655–2669) entitled “Genome-Wide Architecture of Disease Resistance Genes in Lettuce,” Figure 1 on page 2659 contained unintentionally duplicated images. This inaccuracy, which did not alter the message of the figure, has now been corrected.
