Figure 3From: Frequent loss of lineages and deficient duplications accounted for low copy number of disease resistance genes in CucurbitaceaeAn integrated map of R loci in Cucurbitaceae. R-genes from cucumber, melon and watermelon were mapped onto the 7 chromosomes of Cucumber cultivar 9930. R loci from cucumber, melon and watermelon were in green, yellow and red, respectively. Each R locus may contain several R-genes. The two translocation events are marked as numbers â‘ and â‘¡.Back to article page
