Fig 4

Physical cluster 92 is located on chromosome 18 and comprises twenty-two CYP82 sequences, one CYP74 sequence and one CYP704 sequence. The dots and the black lines represent the sequence similarities in cluster 92 compared to itself. The red rectangles on the sides of the graph represent cytochrome P450 sequences. Complete genes are labeled with their name and pseudogenes are labeled with “p” and the P450 family. A) The similarities for the whole cluster 92. B) A zoom of the red squared region, which contains two 30kb blocks with very high similarity. Analysis of gene expression showed that CYP82D15 and CYP82D18 are co-expressed (expression cluster A, expression in ripe berries) as well as CYP82D17 and CYP82D20v2 (expression cluster C, expression in downy mildew infected leaves). The pseudogenes of the enlarged segment are not expressed.
