A strategy to control bean infectiousdiseases, mainly those caused by fungi, is based on the use of biocontrol agents(BCAs) that can reduce the negative effects of plant pathogens and also can promotepositive responses in the plant. Trichoderma is a fungal genus that is able to inducethe expression of genes involved in plant defense response and also to promote plantgrowth, root development and nutrient uptake. In this article, a strategy that combinesin silico analysis and real time PCR to detect additional bean defense-related genes,regulated by the presence of Trichoderma velutinum and/or R. solani has been applied.Based in this strategy, from the 48 bean genes initially analyzed, 14 were selected, andonly WRKY33, CH5b and hGS showed an up-regulatory response in the presence ofT. velutinum. The other genes were or not affected (OSM34) or down-regulated by thepresence of this fungus. R. solani infection resulted in a down-regulation of most ofthe genes analyzed, except PR1, OSM34 and CNGC2 that were not affected, and thepresence of both, T. velutinum and R. solani, up-regulates hGS and down-regulatesall the other genes analyzed, except CH5b which was not significantly affected. Asconclusion, the strategy described in the present work has been shown to be effectiveto detect genes involved in plant defense, which respond to the presence of a BCA orto a pathogen and also to the presence of both. The selected genes show significanthomology with previously described plant defense genes and they are expressed inbean leaves of plants treated with T. velutinum and/or infected with R. solani.
