Journal ArticleDOI
Transgenic expression of the Trichoderma harzianum hsp70 gene increases Arabidopsis resistance to heat and other abiotic stresses
Marta Montero-Barrientos,Rosa Hermosa,Rosa E. Cardoza,Santiago Gutiérrez,Carlos Nicolás,Enrique Monte +5 more
TL;DR: Results indicate that hsp70 confers tolerance to heat and other abiotic stresses and that the fungal HSP70 protein acts as a negative regulator of the HSF transcriptional activity in Arabidopsis.
Journal ArticleDOI
Overexpression of a Trichoderma HSP70 gene increases fungal resistance to heat and other abiotic stresses.
Marta Montero-Barrientos,Rosa Hermosa,Carlos Nicolás,Rosa E. Cardoza,Santiago Gutiérrez,Enrique Monte +5 more
TL;DR: The overexpression of hsp70 in T. harzianum T34 gave rise to transformants with higher quantities of biomass obtained after heat shock treatment, and these transformants showed an enhanced tolerance to oxidative, osmotic and salt stresses when conidia were previously treated at 45 degrees C for 2h.
Journal ArticleDOI
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.
TL;DR: The results show that nox1 is involved in T. harzianum ROS production and antagonism against P. ultimum, and genes related to protease, cellulase, and chitinase activities were differentially upregulated in the interaction of aNox1-overexpressed transformant with this pathogen.
Journal ArticleDOI
The overexpression in Arabidopsis thaliana of a Trichoderma harzianum gene that modulates glucosidase activity, and enhances tolerance to salt and osmotic stresses.

TL;DR: Data presented throughout this article suggest the high value of T. harzianum as a source of genes able to facilitate the achievement of producing plants resistant to abiotic stresses without alteration of their phenotype.
Journal ArticleDOI
The heterologous overexpression of hsp23, a small heat-shock protein gene from Trichoderma virens, confers thermotolerance to T. harzianum.
TL;DR: An EST showing high values of identity with genes coding for small heat shock proteins (sHSPs) was selected from an EST library collection of Trichoderma virens T59 and the cDNA gene (hsp23) with a sequence size of 645 bp long was amplified by PCR.
