As the early response is likely to have influential effects on infection outcome, we focused on the four candidate TFs in Group 1 (induction at 0.5 hr); the genes CAGL0F00561g, CAGL0G02739g, CAGL0L03157g, and CAGL0J04400g are uncharacterized and annotated as the Saccharomyces cerevisiae orthologue of RPA12, XBP1, DAL80, and HAP3, respectively. The gene discussed is POLR1H; the disease is infection.
