“…It is suspected that the secondary metabolites of T. harzianum can produce growth regulators, such as hormones that can stimulate plant growth. This is in accordance with the opinion of Haneefat, et al (2012), that application of T. harzianum secondary metabolites can increase gibberellins in plant roots. According to Bidadi, et al (2010), the increase of adventitious and primary root length is caused by hormones' influence.…”

Damping-off is one of the main diseases in cucumber seedlings caused by Pythium sp. Secondary metabolites of Trichoderma harzianum T10 can conduct the control of the disease. The pH of the medium influences the production of secondary metabolites. The research aimed to determine the effective pH medium on production of T. harzianum T10 secondary metabolites, and the effect of the T. harzianum T10 secondary metabolites application in damping-off disease control also to the growth of cucumber seedling. The research was consist of two steps; 1) in vitro assay with various pH levels 5; 3; 3.5; 4; 4.5; 5.5; 6; 6.5; and 7, 2) In planta treatments consisted of control, fungicide (Mancozeb), secondary metabolites in pH 5 and 5.5 with the concentration of 5, 10 and 15% each. The research showed that: 1) the effective pH medium for the production of T. harzianum T10 secondary metabolites was 5 and 5.5. 2) application of the T. harzianum T10 secondary metabolites on pH 5 and 5.5 with a concentration of 5, 10, and 15% could decrease the disease incidence and support cucumber seedling growth.

“…In many studies Trichoderma spp. could improve the growth of some medicinal plants by producing phytohormones such as gibberellins, auxin, and cytokinins (Sofo et al 2011;Hanefat et al 2012;Martínez-Medina et al 2014;Resende et al 2014).…”

The current study was taken up to examine the role of bioagent (Trichoderma hamatum) in mitigating the deleterious effects of NaCl stress in Ochradenus baccatus. Varying concentrations of salt (0, 75, and 150 mM) were used to observe the effect on growth, pigments, some key metabolic attributes, antioxidant enzymes, and elemental accumulation in O. baccatus. The results indicated significant decrease in seed germination, plant growth, pigment content, membrane stability index, tissue water content, and total lipid content with salt stress. Lipid peroxidation increases with the increasing concentration of NaCl. Moreover, salinity stimulated the biosynthesis of phenols, diacylglycerol, sterol esters, nonesterified fatty acids, and enzymatic antioxidants like superoxide dismutase, catalase, peroxidase, ascorbate peroxidase, glutathione reductase. The Na + content in shoot increases with elevated levels of NaCl concentration, accompanied with significant decreases in K + , Mg 2+ , and Ca 2+ . Application of bioagent (T. hamatum) has been observed to alleviate the antagonistic effect of salt stress on plant growth and metabolic processes. In absence and presence of salt stress, the bioagent stimulated the plant growth and alter the plant metabolism through the modification of the above parameters.

“…The phytohormone levels particularly auxin and gibberllin were accumulated significantly high in soybean plants when treated with T. harzianum and Glomus mosseae (an AMF) in combination compared to untreated plants and plants treated with T. harzianum and G. mosseae individually. The observations suggest that there was a synergistic interaction between T. harzianum and G. mosseae that resulted in better plant growth [63]. Saprophytic and nonpathogenic strains of Trichoderma reduce the fungal diseases in a variety of plants.…”

Trichoderma species are known globally mostly for the production of industrially useful enzymes as well as their biocontrol ability against plant pathogens. One of the major strategies of biological control is mycoparasitism against fungal pathogens of crop plants. However, till recently the mechanisms of mycoparasitism by biocontrol potential Trichoderma species at molecular level were not clearly understood. The biochemical signaling and the involvement of secondary metabolites that lead to mycoparasitic activities of Trichoderma, in particular, were not very clearly known earlier. Recent findings in this regard revealed that there are a number of signaling cascades activated during the process of mycoparasitism by Trichoderma species against phytopathogenic fungal pathogens. In addition Trichoderma also interacts with beneficial root inhabiting fungi like mycorrhizae. The interaction of Trichoderma species with mycorrhizal fungi is different as during interaction with mycorrhizal fungi different signaling cascades are activated that lead to a synergistic action. In the current review, we gathered updated evidences regarding the signaling cascades that are generated during interactions between Trichoderma species with fungal pathogens resulting mycoparasitism as well as interactions of Trichoderma species with mycorrhizal fungi resulting synergism at molecular level. We also highlighted the role of secondary metabolites that are reported to be associated in the signaling processes.
