Comprehensive Identification of Salmonella enterica Serovar Typhimurium Genes Required for Infection of BALB/c Mice
Figure 8
TMDH data obtained from array set 6 for SPI-2 and the surrounding regions.
Genes are coloured according to their GC content as indicated by the scale bar. The region of SPI-2 that encodes a type-III secretion system can be identified by its low GC content. The TMDH signals within this region are abolished in the output datasets, indicating that transposon insertions in this region are attenuating. Insertions in the flanking regions give comparable signals in the input and output datasets.
