Comparative Genomic Hybridization (CGH) microarray results. Comparative Genomic Hybridization (CGH) microarray results. Individual values presented are the base 2 logarithm of the fluorescence ratios of two Arabidopsis thaliana genomic DNA samples hybridized to slide features. Features are ordered left to right by position on chromosomes 1 through 5. The constriction on each chromosome marks the location of the centromere, each arbitrarily one million base pairs (Mbp) wide in this diagram. Dark bars flanking centromeres mark pericentromeric regions where Athila retrotransposon loci are present in the sequenced genome. Panels (A) and (B) present the same values overlaid with a blue line presenting a 15-point running mean in panel (A) and a 101-point running mean in panel (B); values are the feature hybridization signals of accession Loh-0, relative to the sequenced accession Col-0. Note that the array was constructed using information from the sequenced Col-0 accession. Panel (C) presents the ratios of a CGH selfself hybridization assay with accession Col-0. Panel (D) values are of an aneuploid individual with three copies of chromosomes 1, 3 and 4 and two copies of chromosomes 2 and 5. Values are relative to feature signals from a diploid individual; from Henry et al. (2006), see this for additional information.
