Transgenic expression of the Trichoderma harzianum hsp70 gene increases Arabidopsis resistance to heat and other abiotic stresses.
The ability of some Trichoderma strains, a biological control agent, to overcome extreme environmental conditions has previously been reported and related to heat-shock proteins (HSPs). TheseExpand
Identification of Loci and Functional Characterization of Trichothecene Biosynthesis Genes in Filamentous Fungi of the Genus Trichoderma †
ABSTRACT 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) clusterExpand
The contribution of Trichoderma to balancing the costs of plant growth and defense.
Trichoderma is a fungal genus of cosmopolitan distribution and high biotechnological value, with several species currently used as biological control agents. Additionally, the enzyme systems of theExpand
Generation, annotation, and analysis of ESTs from four different Trichoderma strains grown under conditions related to biocontrol
The functional genomics project “TrichoEST” was developed focused on different taxonomic groups of Trichoderma with biocontrol potential. Four cDNA libraries were constructed, using similar growthExpand
Characterization and nitrogen-source regulation at the transcriptional level of the gdhA gene of Aspergillus awamori encoding an NADP-dependent glutamate dehydrogenase
Abstract A 28.7-kb DNA region containing the gdhA gene of Aspergillus awamori was cloned from a genomic DNA library. A fragment of 2570 nucleotides was sequenced that contained ORF1, of 1380 bp,Expand
Evolution of structural diversity of trichothecenes, a family of toxins produced by plant pathogenic and entomopathogenic fungi
Trichothecenes are a family of terpenoid toxins produced by multiple genera of fungi, including plant and insect pathogens. Some trichothecenes produced by the fungus Fusarium are among theExpand
Involvement of Trichoderma Trichothecenes in the Biocontrol Activity and Induction of Plant Defense-Related Genes
ABSTRACT Trichoderma species produce trichothecenes, most notably trichodermin and harzianum A (HA), by a biosynthetic pathway in which several of the involved proteins have significant differencesExpand
Functional Analysis of the Trichoderma harzianum nox1 Gene, Encoding an NADPH Oxidase, Relates Production of Reactive Oxygen Species to Specific Biocontrol Activity against Pythium ultimum †
ABSTRACT The synthesis of reactive oxygen species (ROS) is one of the first events following pathogenic interactions in eukaryotic cells, and NADPH oxidases are involved in the formation of such ROS.Expand
ThPTR2, a di/tri-peptide transporter gene from Trichoderma harzianum.
The generation of a wide ESTs library and database from Trichoderma harzianum CECT 2413 was the base for identifying the gene ThPTR2, coding for a PTR family di/tri-peptide transporter. The deducedExpand
Overexpression of the trichodiene synthase gene tri5 increases trichodermin production and antimicrobial activity in Trichoderma brevicompactum.
Trichoderma brevicompactum produces trichodermin, a simple trichothecene-type toxin that shares the first steps of the sesquiterpene biosynthetic pathway with other phytotoxic trichothecenes fromExpand
