Overexpression of the Trichoderma brevicompactum tri5 Gene: Effect on the Expression of the Trichodermin Biosynthetic Genes and on Tomato Seedlings
Trichoderma brevicompactum IBT 40841 produces trichodermin, a trichothecene-type toxin that shares most of the steps of its biosynthesis with harzianum A, another trichothecene produced by several Trichoderma species. The first specific step in the trichothecene biosynthesis is carried out by a terpene cylcase, trichodiene synthase, that catalyzes the conversion of farnesyl pyrophosphate to tri...
متن کاملThe Elicitation Effect of Pathogenic Fungi on Trichodermin Production by Trichoderma brevicompactum
The effects of six species of phytopathogenic fungi mycelia as elicitors on trichodermin yield by Trichoderma brevicompactum were investigated. Neither nonviable nor viable mycelia of Botrytis cinerea, Alternaria solani, Colletotrichum lindemuthianum, and Thanatephorus cucumeris demonstrated any elicitation on the accumulation of trichodermin. However, the production of trichodermin was increas...
متن کاملTranscriptome Sequencing and Gene Expression Analysis of Trichoderma brevicompactum under Different Culture Conditions
BACKGROUND Trichoderma brevicompactum is the Trichoderma species producing simple trichothecenes-trichodermin, a potential antifungal antibiotic and a protein synthesis inhibitor. However, the biosynthetic pathway of trichodermin in Trichoderma is not completely clarified. Therefore, transcriptome and gene expression profiling data for this species are needed as an important resource to better ...
متن کاملFusarium Tri4 encodes a multifunctional oxygenase required for trichothecene biosynthesis.
Fusarium graminearum and Fusarium sporotrichioides produce the trichothecene mycotoxins 15-acetyldeoxynivalenol and T-2 toxin, respectively. In both species, disruption of the P450 monooxygenase-encoding gene, Tri4, blocks production of the mycotoxins and leads to the accumulation of the trichothecene precursor trichodiene. To further characterize its function, the F. graminearum Tri4 (FgTri4) ...
متن کاملIdentification of loci and functional characterization of trichothecene biosynthesis genes in filamentous fungi of the genus Trichoderma.
Trichothecenes are mycotoxins produced by Trichoderma, Fusarium, and at least four other genera in the fungal order Hypocreales. Fusarium has a trichothecene biosynthetic gene (TRI) cluster that encodes transport and regulatory proteins as well as most enzymes required for the formation of the mycotoxins. However, little is known about trichothecene biosynthesis in the other genera. Here, we id...
