<i>Trichoderma paratroviride</i> Strain 8942: Mechanisms of <i>Phytophthora infestans</i> Inhibition and Tomato Growth Promotion.

ABSTRACT: Tomato late blight caused by Phytophthora infestans is a devastating disease, and current control of the disease relies heavily on chemical fungicides. Certain Trichoderma strains used as biocontrol fungi have shown superb efficacy against P. infestans and some other oomycete phytopathogens. In this study, T. paratroviride strain 8942 appeared to be effective in control of tomato late blight disease, reducing the necrosis degree of plant tissues, promoting callose deposition in tomato leaves, and increasing defense enzyme activities. RT-qPCR analysis showed that strain 8942 inhibited metabolism of salicylic acid and promoted metabolism of jasmonic acid at the early stage of colonization. In addition, root colonization of the strain significantly promoted tomato
