Figure 1.

A graphical representation of the study performed by Dermauw et al. (2012) [21]. (a) represents the transcriptional changes in the susceptible London strain of the T. urticae Koch when changing host plant. (b) represents the number of genes expressed in two resistant strains and the susceptible London strain of T. urticae Koch after 5 generations from the relocation to another host plant. The scheme was constructed by R.A. Rincón for this review from the data published by Dermauw et al. (2012) [21].
