Finished Genome of the Fungal Wheat Pathogen Mycosphaerella graminicola Reveals Dispensome Structure, Chromosome Plasticity, and Stealth Pathogenesis
Figure 2
Box plots of comparative genome hybridizations (CGH) of DNA from five isolates of Mycosphaerella graminicola to a whole-genome tiling array made from the finished sequence of isolate IPO323.
A, CGH between IPO323 and the Dutch field isolate IPO94269. B, CGH between IPO323 and progeny isolate #51 from the cross between IPO323 and IPO94269. C, CGH between IPO323 and progeny isolate #2133 of the cross between IPO323 and IPO95052. D, CGH between IPO323 and Algerian field isolate IPO95052, which was isolated from and is adapted to durum (tetraploid) wheat. The genomic difference between the strains for each CGH is shown by 21 box plots, one for each chromosome of M. graminicola. The horizontal line in each box is the median log ratio of hybridization signals of the two strains; the upper and lower ends of a box represent the 25% and 75% quartiles. The whiskers extending from each box indicate 1.5 times the interquartile range, the distance between the 25% and 75% quartiles. The larger the deviation from 0, the greater the difference between the strains for a particular chromosome. Pink boxes that are significantly less than the zero line indicate missing chromosomes. The purple boxes in panel B (4 and 18) that are significantly higher than the zero line indicate chromosomes that are disomic.
