For two of them (putative ornithine decarboxylase and triacyl glycerol lipase), a weak down-regulation in response to infection could be confirmed, though levels were far less than expected based on the fold-change ratios obtained for the SuperSAGE libraries, and one gene (cysteine synthase) even showed the opposite effect while at the same time a putative nuclear transport factor and myb-related protein 308 were unchanged (S4 Fig). The gene discussed is ODC1; the disease is infection.
