Plot of Actinidia deliciosa versus A. eriantha microarray intensities. Genomic DNA was labeled with cy3 and cy5 in two separate reactions, combined and hybridized to a single microarray slide. Spots not found or flagged "bad" were removed and each channel was normalized using a quantile normalization. Of the two arrays, 15,024 were flagged "good" using A. deliciosa DNA and 13,785 were flagged "good" using A. eriantha DNA. Of these spots, 13,443 were common to both species. Black spots represent oligonucleotides that showed similar intensity of hybridization between the two species. Triangles represent oligonucleotides that showed an increase in intensity with A. eriantha genomic DNA and crosses represent oligonucleotides that showed an increase using A. deliciosa genomic DNA.
