TFPI and infection: Although the transcriptome heat map did not find such a consistent pattern of expression for the other three EPS gene clusters in the Δrel mutant, it was interesting to note that a large proportion of the EPS I and EPS III genes were up-regulated at time 0 of the simulated infection process and down-regulated at the end (Fig. 2A; Table S5), while the reverse was true for EPS II.
