“…These results were consistent with those of Yoshioka et al [51], who described the ability of a cell-free CF of Trichoderma asperellum STK-1 to induce systemic resistance in A. thaliana, decrease lesion development and growth of the pathogen P. syringae pv. Tomato DC3000.…”

Two different species, Trichoderma viride TV10 and Trichoderma harzianum TH12 from 30 Trichoderma isolates were selected out based on their high growth inhibition of the phytopathogen Sclerotinia sclerotiorum (Lib) de Bary, which reached 84.44% and 100%, respectively. Their untreated culture filtrates (CF) and culture filtrates treated with heat (CFH) also were tested for growth inhibition of the pathogen in potato dextrose agar (PDA). Morphological and molecular characterisation by internal transcribed spacer (ITS) PCR provided consistent identification of these isolates. The degree of infection and disease index (DI) of S. sclerotiorum were examined in Brassica napus (AACC) and Raphanus alboglabra (RR) and Brassica alboglabra (CC). The results revealed that Raphanus alboglabra showed higher disease resistance than that of B. napus. Biotic elecitors T. harzianum TH12 and T. viride TV10 and their CF and CFH demonstrated the ability to cause induced systemic resistance (ISR) in B. napus and Raphanus alboglabra against sclerotinia stem rot (SSR) disease. Furthermore, a high ability to reduce the degree of infection and DI in B. napus with the biotic elicitors T. harzianum TH12 and T. viride TV10 was observed, with numbers reaching 7.22% to 6.67% and 17.78% to 11.67%, respectively. When CF were used, reached 20.00% to 16.67% and 33.33% to 23.33%, respectively; with CFH, values reached 35.00% to 21.67% and 37.78% to 28.33%, respectively. While in Raphanus alboglabra the degree of infection and DI * Corresponding authors. J. T. Alkooranee et al. 1663reached 0.00% and 0.00% with all biotic elicitors treatments. These results show that biotic elicitor treatments significantly (P < 0.05) can increase the fresh and dry weights of both roots and shoots as well as plant height compared with controls. The TH12 treatment in B. napus and Raphanus alboglabra ranked as most effective. This study showed for the first time the ability of genotype Raphanus alboglabra (RRCC) to demonstrate resistance against S. sclerotiorum with or without treatment by biotic elicitors and the ability of genotype B. napus (AACC) to demonstrate resistance to the pathogen after treatment with biotic elicitors.

“…Recent findings include: (i) the colonization of Arabidopsis roots by T. atroviride induces a delayed and overlapping expression of the defence-related genes of the SA and JA/ ET pathways against biotrophic and necrotrophic phytopathogens, both locally and systemically (Salas-Marina et al, 2011); (ii) Trichoderma is able to trigger a long-lasting upregulation of SA gene markers in plants unchallenged by pathogens, although when plants are infected by a pathogen such as B. cinerea, the pretreatment with Trichoderma may modulate the SA-dependent gene expression and, soon after infection, the expression of defence genes induced through the JA signal transduction pathway occurs, causing ISR to increase over time (Tucci et al, 2011); and (iii) colonization of Arabidopsis root by T. asperellum produces a clear ISR through an SA signalling cascade, and both the SA and JA/ET signalling pathways combine in the ISR triggered by cell-free culture filtrates of Trichoderma (Yoshioka et al, 2011).…”

Plant-beneficial effects of Trichoderma and of its genes

Trichoderma (teleomorph Hypocrea) is a fungal genus found in many ecosystems. Trichoderma spp. can reduce the severity of plant diseases by inhibiting plant pathogens in the soil through their highly potent antagonistic and mycoparasitic activity. Moreover, as revealed by research in recent decades, some Trichoderma strains can interact directly with roots, increasing plant growth potential, resistance to disease and tolerance to abiotic stresses. This mini-review summarizes the main findings concerning the Trichoderma-plant interaction, the molecular dialogue between the two organisms, and the dramatic changes induced by the beneficial fungus in the plant. Efforts to enhance plant resistance and tolerance to a broad range of stresses by expressing Trichoderma genes in the plant genome are also addressed.

“…T. harzianum strain T-22 is the only microbe reported to induce systemic resistance to pathogens in model plants (Contreras-Cornejo et al, 2011;Salas-Marina et al, 2011;Yoshioka et al, 2012) and also in maize indicative of its unique ability (Harman et al 2012). Induced systemic resistance is believed to be one of the most important mechanisms of biocontrol effects of Trichoderma (Harman, 2006).…”

The novel technologies in all areas of agriculture have improved agricultural production, but some modern practices affect the environment. The recent challenge faced by advanced farming is to achieve higher yields in environment-friendly manner. Thus, there is an immediate need to find eco-friendly solutions such as wider application of biocontrol agents. Among various types of species being used as biocontrol agents, including fungi and bacteria, fungal genus Trichoderma produces different kinds of enzymes which play a major role in biocontrol activity like degradation of cell wall, tolerance to biotic or abiotic stresses, hyphal growth etc. The understanding of filamentous fungi belonging to the genus Trichoderma has continuously evolved since last two decades, from the simple concepts of biocontrol agents to their recently established role as symbionts with different beneficial effects to the plants. Recent findings from structural and functional genomics approaches suggest the additional use of these microbes as model to study mechanisms involved in multiple player interactions that is, microbes-microbes-plant-environment. In this work, historical development of Trichoderma spp., mode of action against different biological agents, potential applications and recent mass production techniques are summarized and discussed in detail with updated advances with their application in the agriculture and sustainable environment.
