Schematic of the microsynteny between the R gene clusters at the Ph-3 locus in S. pimpinellifolium L3708 and S. lycopersicum Heinz1706. The green arrows at the top show the R gene homologs in the L3708 BAC sequence, and the yellow arrows at the bottom indicate RGAs at the corresponding locus of Heinz1706. The transcriptional orientations are indicated by the direction of arrows. The orange, purple and blue lines linking the L3708 and Heinz1706 sequences indicate an identity above 95, 90–95, and 85–90 %, respectively
