Figure 6Most of the DEGs are unique to fungal species . Intersection between up- and down-regulated genes under all conditions. The numbers of up-regulated (a, c, e, g) and down-regulated (b, d, f, h) genes under each condition for each strain are reported. (a and b) AK83; (c and d) BL225; (e and f) Rm1021; (g and h) hybrid strain. Each row of the matrix corresponds to a Trichoderma treatment, with the number of up-regulated/down-regulated genes reported to the left as a bar plot. Each column corresponds to one intersection: cells are either empty, indicating that up- or down-regulated genes under the specified conditions are not part of the intersection, or filled, indicating that the genes present under the specified conditions are participating at the intersection. Bars on the top show the size of the intersection reported on the bottom. TG, T. gamsii ; TH, T. harzianum ; TV, T. velutinum ; TT, T. tomentosum .
