FIG 8.

qPCR analysis of the relative expression levels of Trichoderma arundinaceum IBT 40837 (Ta37) tri5 in roots of tomato hydroponic cultures inoculated with T34-5.27-b1 (A) and of Ta37 tri5 and tri4 in roots of tomato hydroponic cultures inoculated with T34-5.27-tri4.2 (B), in both cases versus the level of expression in 96-h mycelia of the T34-5.27-tri4.2 strain. (C) Relative expression level of tri5 in roots of tomato hydroponic cultures inoculated with T34-5.27-tri4.2 versus the level detected in roots inoculated with the recipient strain T34-5.27-b1. Calculations and graphic representations were performed as indicated in the legend to Fig. 3. Note that the expression of tri4 was not detected in roots of tomato hydroponic cultures inoculated with strain T34-5.27-b1.
