Graphic summary of caste- and treatment dependent inducibility and function of eight detoxification and immune-related genes of the Formosan subterranean termite.

<p>Treatment consisted of exposure to a xenobiotic substance (0.5% phenobarbital) or septic injury via bacteria injection. Relative levels of caste (workers vs. soldiers) dependent induced gene expression are indicated with +++ in red (>4 fold expression change compared to control), ++ in orange (2–4 fold expression change), + in yellow (<2 fold expression change) or – in grey (no significant induction). Genes are arranged from left to right according their putative function ranging from detoxification to immunity and from top to bottom according to their caste dependent expression.
