Regulation of the type VI secretion system tss-5 cluster. The heat-map shows the expression ratio of each gene in the T6SS tss-5 cluster during intracellular growth in host macrophages relative to in vitro growth. Expression values are determined from the SAM analysis with red representing up-regulation (ratio of +8.0) and green representing down-regulation (ratio of -8.0) on a log2 scale.
