Induced systemic resistance in cucumber and Arabidopsis thaliana by the combination of Trichoderma harzianum Tr6 and Pseudomonas sp. Ps14

► Trichoderma and Pseudomonas strains were isolated from cucumber rhizosphere. ► Strains were tested for eliciting systemic resistance against Fusarium in cucumber. ► Combining Trichoderma and Pseudomonas leads to enhanced induced resistance. ► This enhanced effectiveness is observed in cucumber but not in Arabidopsis. ► In cucumber the enhanced effectiveness is paralleled by enhanced priming of defense genes.
