Dada la importancia de las hidrolasas de paredes celulares en el antagonismo, en este trabajo se estableció como primer objetivo: 1. Obtención de cepas de Trichoderma harzianum mejoradas en su capacidad antagonista por sobreexpresión del gen bgn16.2, que codifica una β-1,6-glucanasa. Optimación de las condiciones de cultivo (pH y ausencia de...

Using a differential display technique, the gene gtt1, which codes for a high-affinity glucose transporter, has been cloned from the mycoparasite fungus Trichoderma harzianum CECT 2413. The deduced protein sequence of the gtt1 gene shows the 12 transmembrane domains typical of sugar transporters, together with certain residues involved in...

The capacity of the fungus Trichoderma harzianum CECT 2413 to colonize roots and stimulate plant growth was analyzed. Tobacco seedlings (Nicotiana benthamiana) transferred to Petri dishes inoculated with T. harzianum conidia showed increased plant fresh weight (140%) and foliar area (300%), as well as the proliferation of secondary roots (300%)...

Background: The filamentous fungus Trichoderma harzianum is used as biological control agent of several plant-pathogenic fungi. In order to study the genome of this fungus, a functional genomics project called "TrichoEST" was developed to give insights into genes involved in biological control activities using an approach based on the...
