Arabidopsis CGH array data for mutant lines ga1-3 , FN1148, E124, E99 and E207. The CGH data is displayed as a single panel log₂ signal ratio (mutant/control) rainbow plot for all probes plotted versus genome position, with each chromosome (1-5) differentiated by vertical dashed lines. Strongly negative points (e.g. −2 to −6) represent potential deletion mutations, strongly positive points (e.g. 2 to 6) represent potential duplication mutations. The known deletions in each mutant line are highlighted by an arrow and the name of the gene affected. Data is normalized and segmented. Putative deletions in ga1-3 are shown with a ‘*’, and a confirmed deletion of ~7 kb in E99 is shown with a ‘∆’. The staggered ‘ultra-high density’ probes covering the larger deletions in the FN1148 (~500 bp AtHKT1 genic mutation) and ga1-3 (~5 kb AtGA1 genic mutation) Arabidopsis mutants were staggered every 6 bp, while the extra probes representing the smaller deletions in the E124 (104 bp AtPHYB genic mutation), E99 (28 bp AtHY1 genic mutation) and E207 (4 bp AtMAX2 genic mutation) Arabidopsis mutants were staggered every 2, 6, 10, 12, 15, 17, 20, 22, 25, 27, 30, 32, 35, 37, 40, 42, 45, 47 and 49 bp.
