Fig. 1From: Variability among Cucurbitaceae species (melon, cucumber and watermelon) in a genomic region containing a cluster of NBS-LRR genesSyntenic relationships between the resistance gene clusters in melon, cucumber and watermelon. Genes are represented by vertical lines, in blue if they are NBS-LRR genes. NBS-LRR clusters are highlighted in grey boxes. Red lines indicate syntenic regions. Direction of transcription of all genes is left to right, except for cucumber which has been reoriented for practical reasons. Chromosome 9 region from melon spans 221Â kb from gene MELO3C022168 to MELO3C022141. In cucumber, the syntenic region in chr5 spans 176Â kb, from gene Cucsa.237600 to Cucsa.237270 (right to left). Finally, the chromosome 8 region in watermelon (384Â kb) includes genes from Cla012442 to Cla012422. The gap of 110Â kb in watermelon (asterisk) is composed basically of NsBack to article page
