Genetic engineering has brought improvements of Trichoderma species for biotechnological processes such as agriculture. It has previously been reported that sm1 and aquaglyceroporin genes from Trichoderma harzianum are strongly expressed during pathogens biocontrol. We have previously shown that Sm1 plays a significant role in plant disease resistance and aquaporin (AQP) regulate physiological processes and responses related to water stress. Here, we report the evaluation of mutant lines with sm1 (deleated) and aqp (overexpressed) in Phaseoulus vulgaris growth promotion and disease resistance induction. It was investigated plants physiological and biochemical responses, plant growth promotion and biocontrol of Sclerotinia sclerotiorum, the causal agent of white mold. Treatments included Trichoderma harzianum wyld type, mutant line overexpressing aquaporin (Aqua), and deleted ΔEpl1mutant line. Our results demonstrated that Aqua mutant line increased leaf area in 25%, in comparison to non-treated plants. It also differed from other treatments, in comparison to plants with treatments ALL-42 and ΔEpl1, which increased 28% and 91%, respectively (Isso é abstract, ta confuse e extensor. Specific activity of β-1.3 glucanase was higher in plants treated with T. harzianum ΔEpl1 mutant isolate, in leaves and roots respectively with 2.07 Umg-¹ and 2.57 Umg-¹. Plants inoculated or not with S. sclerotiorum presented with 2.27 Umg -1 and 2.34 Umg -1 of β-1.3 glucanase on average, respectively, but enzymatic activity was higher on leaves when compared to the roots. The Aqua mutant demonstrated excellent growth promoting properties. Both mutants of T. harzianum do not induce resistance to white mold on common bean plants.

-The objective of this work was to evaluate, in vitro and in vivo, the potential of Trichoderma spp. strains to control Sclerotinia sclerotiorum in soybeans (Glycine max) and to perform the molecular identification of the best performing strains. The effect of 120 strains of Trichoderma spp. on the viability of S. sclerotiorum sclerotia was evaluated in vitro through immersion in suspension of conidia from the antagonists and plating in culture medium. The best performing strains were evaluated in vivo, in a greenhouse, for control of the pathogen inoculated on 'Pintado' soybean seeds and plants. Of the 120 strains tested in vitro, 22 strains of Trichoderma spp. caused 100% inhibition of sclerotia germination. In the greenhouse, five strains inhibited the negative effect of the pathogen on seed germination and two strains increased in up to 67% plant dry matter. The best performing strains were identified as T. koningiopsis (3 strains), T. asperelloides (3), T. atroviride (2), and T. virens (1). Trichoderma strains are able to protect soybean plants from the harmful effect of S. sclerotiorum and, at the same time, they can promote the growth of the aerial part in greenhouse conditions.

Fungos do gênero Trichoderma são uns dos principais micro-organismos de importância para o aumento do crescimento vegetal. Desta forma, objetivou-se com este trabalho avaliar a eficiência da inoculação de Trichoderma asperellum UFT 201, como promotores de crescimento vegetal nas culturas da soja, feijão caupi, arroz e milho, em casa de vegetação. As características de biomassa das culturas foram determinadas através da massa seca da parte aérea, massa seca da raiz e massa seca total, bem como a eficiência relativa. Nas diferentes culturas estudadas, a inoculação de T. asperellum UFT 201 foi superior para as características de biomassa, mostrando o potencial como promotor de crescimento, com aumento acima de 60% em relação à testemunha, para todas as culturas. Os resultados demonstram a capacidade do inoculante Trichoderma asperellum UFT 201, em promover o crescimento inicial de plantas, como observado para as culturas estudadas.
