“…A few studies have claimed production of simple trichothecene-type toxins by species of Trichoderma (Adams and Hanson 1972; Bamburg and Strong 1969;Watts et al 1988;Cvetnić and Pepelnjak 1997; see also Sivasithamparam and Ghisalberti 1998 for a review), but in most of the studies, nonspecific analytical methods such as TLC and HPLC were used and no details of taxonomic identification were given. Of these reports, we have only been able to examine the T. polysporum strain (IMI 40624) reported by Adams and Hanson (1972).…”

The Trichoderma brevicompactum clade: a separate lineage with new species, new peptaibiotics, and mycotoxins

et al. 2008

The Brevicompactum clade is recognized as a separate lineage in Trichoderma/Hypocrea. This includes T. brevicompactum and the new species T. arundinaceum, T. turrialbense, T. protrudens and Hypocrea rodmanii. The closest relative of the Brevicompactum clade is the Lutea clade. With the exception of H. rodmanii, all members of this clade produce the simple trichothecene-type toxins harzianum A or trichodermin. All members of the clade produce peptaibiotics, including alamethicins. Strains previously reported as T. harzianum (ATCC 90237), T. viride (NRRL 3199) or Hypocrea sp. (F000527, CBS 113214) to produce trichothecenes are reidentified as T. arundinaceum. The Brevicompactum clade is not closely related to species that have biological application.

“…Subsequently, this compound has been obtained from T. polysporum and T. sporulosum (Adams and Hanson 1972) T. reesei (Watts et al 1988). The deacetyl derivative trichodermol (101) was obtained by hydrolysis of 100 (Godtfredsen and Vangedal 1964), and later isolated as a natural product from T. polysporum and T. sporulosum (Adams and Hanson 1972).…”

Secondary metabolites from species of the biocontrol agent Trichoderma

et al. 2007

Trichoderma species are free-living fungi that are highly interactive in root, soil and foliar environments and have been used successfully in field trials to control many crop pathogens. Structural and biological studies of the metabolites isolated from Trichoderma species are reviewed. This review, encompassing all the literature in this field up to the present and in which 269 references are cited, also includes a detailed study of the biological activity of the metabolites, especially the role of these metabolites in biological control mechanisms. Some aspects of the biosynthesis of these metabolites and related compounds are likewise discussed.

“…Trichoderma isolates were grown on potato dextrose agar medium (PDA) for five days at 258C in the dark and then transferred to light conditions for two days. Following fungus colonies growth on plates, the medium with mycelium were cut into 50 mm plugs (Papavizas 1985;Watts et al 1988;Kubicek et al 2003).…”

Biological control involves the use of beneficial organisms such as Trichoderma that promote positive responses by the plant. Trichoderma species produce and/or release a variety of compounds, including cell wall degrading enzymes and secondary metabolites, which enhance root development, crop productivity and resistance to biotic and abiotic stresses. This study examines the effects of the five Trichoderma strains (M7, KHB, G124-1, G46-3 and G46-7) on milk thistle including morphological characteristics and silymarin accumulation. This research indicated that treating milk thistle by M7 strain, significantly increased the highest branch length of plants, while strain KHB induced the production of silychristin, isosilybin and silymarin. Finally, strain G46-7 dramatically increased silydianin content in milk thistle plant. The findings suggested that certain Trichoderma strains are positive elicitors for promoting growth characteristics and silymarin accumulation in Silybum marianum (L.) Gaertn.
