Bioactive Secondary Metabolites from Trichoderma spp. against Phytopathogenic Fungi

Trichoderma volatiles effecting Arabidopsis: from inhibition to protection against phytopathogenic fungi

Trichoderma species are present in many ecosystems and some strains have the ability to reduce the severity of plant diseases by activating various defense pathways via specific biologically active signaling molecules. Hence we investigated the effects of low molecular weight volatile compounds of Trichoderma asperellum IsmT5 on Arabidopsis thaliana. During co-cultivation of T. asperellum IsmT5...

Bioactive secondary metabolites from Juncaceae species

Bioactive secondary metabolites from Salix tetrasperma Roxb.

Column chromatography of the light petroleum fraction from the methanolic extract of the stem bark of Salix tetrasperma Roxb. (Salicaceae) resulted in the isolation of beta-sitosterol acetate, friedelin, 3beta-friedelinol, beta-amyrin, beta-sitosterol, beta-sitosterol-O-glucoside in addition to palmitic acid. From the dichloromethane fraction of the leaves, catechol and tremulacin were isolated...

Mycorrhizal fungi Glomus spp. and Trichoderma spp. in viticulture (review)

TSVETKOV, I., T. DZHAMBAZOVA, V. KONDAKOVA and R. BATCHVAROVA, 2014. Mycorrhizal fungi Glomus spp. and Trichoderma spp. in viticulture (review). Bulg. J. Agric. Sci., 20: 849-855 Mycorrhizal fungi’s Glomus spp. and Trichoderma spp. are natural components of the healthy vineyard soils. They have the ability to improve nutrition and root resistance to attack by pathogens, and contribute positivel...

Filamentous fungi from extreme environments as a promising source of novel bioactive secondary metabolites

Natural product search is undergoing resurgence upon the discovery of a huge previously unknown potential for secondary metabolite (SM) production hidden in microbial genomes. This is also the case for filamentous fungi, since their genomes contain a high number of "orphan" SM gene clusters. Recent estimates indicate that only 5% of existing fungal species have been described, thus the potentia...
