Trichoderma harzianum Rifai is a well-known biological control agent (BCA) effective against a wide range of phytopathogens. Since colonization and persistence in the target niche is crucial for biocontrol effectiveness we aimed to: (i) shed light on the olive roots colonization process by T. harzianum CECT 2413, (ii) unravel the fate of its biomass upon application, and (iii) study the in planta interaction with the soil-borne pathogen Verticillium dahliae Kleb. Fluorescently-tagged… Expand

Beneficial effect of Trichoderma harzianum strain Ths97 in biocontrolling Fusarium solani causal agent of root rot disease in olive trees
TLDR
Analysis of the biocontrol behavior of a Tunisian strain of T. harzianum against Fso14 provided valuable information on using Ths97 as a beneficial agent to control fusarium root rot disease caused by F. solani in olive trees. Expand
Filamentous fungi as biocontrol agents in olive (Olea europaea L.) diseases: Mycorrhizal and endophytic fungi
TLDR
The present review compiles all the studies existing so far in the biocontrol of these pathogens through the use of mycorrhizal and endophytic filamentous fungi, making a separate section for the genus Trichoderma due to the special interest that their use has generated. Expand
Colonization of Beauveria bassiana 08F04 in root-zone soil and its biocontrol of cereal cyst nematode (Heterodera filipjevi)
TLDR
Beauveria bassiana 08F04 isolated from the surface of cysts is a promising biological control agent for cereal cyst nematodes and its label is aimed for efficient monitoring of colonization in the soil. Expand
The Role of Microbial Inoculants on Plant Protection, Growth Stimulation, and Crop Productivity of the Olive Tree (Olea europea L.)
TLDR
A literature review of articles published during the last 10 years about the role of beneficial microbes on olive tree plant growth and productivity, pathogen control, and alleviation from abiotic stress finds that the endophytic bacterial species Pseudomonas fluorescens and Bacillus sp. Expand
Plant Biostimulants: New Insights Into the Biological Control of Verticillium Wilt of Olive
TLDR
Evaluating the effect of 32 products, including amino acids, micronutrients, microorganisms, substances of natural origin, copper complex-based products, and organic and inorganic salts against the disease under controlled conditions will be useful to select the best candidates for future studies. Expand
The Application of Trichoderma Strains or Metabolites Alters the Olive Leaf Metabolome and the Expression of Defense-Related Genes
TLDR
The effects of repeated applications of selected Trichoderma strains or SMs on young olive trees on the stimulation of plant growth and on the development of olive leaf spot disease caused by Fusicladium oleagineum are analyzed. Expand
Desirable Traits of a Good Biocontrol Agent against Verticillium Wilt
TLDR
Issues such as large scale production, formulation, preservation conditions, shelf life, and application methods should be considered early in the process of selecting BCAs against Verticillium. Expand
Feeding the Microbes: A Strategy to Control Verticillium Wilt
TLDR
Soil application of common microbiological growth media can influence the plant—microbe interactions and, subsequently, offer protection against V. dahliae, and the addition of Nutrient Broth and Potato Dextrose in non-sterilized soil reduced Verticillium wilt symptoms in eggplants. Expand
Antagonistic potential of a psychrotrophic fungus: Trichoderma velutinum ACR-P1
TLDR
The psychrotrophic strain is endowed with immense potential to be included as a new candidate in the list of biocontrol agents (BCA) and can be exploited in fields to get rid of devastating impacts of these phytopathogens on the crops. Expand
An Endophytic Trichoderma Strain Promotes Growth of Its Hosts and Defends Against Pathogen Attack
TLDR
The fungus grows on high NaCl or mannitol concentrations, and shows predatory capability on the pathogenic fungus Alternaria brassicicola, and beneficial features of the novel Trichoderma strain are important prerequisites for agricultural applications. Expand

Colonization process of olive tissues by Verticillium dahliae and its in planta interaction with the biocontrol root endophyte Pseudomonas fluorescens PICF7
TLDR
Early and localized root surface and root endophytic colonization by P. fluorescens PICF7 is needed to impair full progress of verticillium wilt epidemics in olive. Expand
Microscopic and transcriptome analyses of early colonization of tomato roots by Trichoderma harzianum.
TLDR
The molecular mechanism underlying fungal ability to colonize the tomato-root system, the T. harzianum transcriptome was analyzed during the early stages of the plant-fungus interaction and the expression of fungal genes related to redox reactions, lipid metabolism, detoxification, and sugar or amino-acid transport increased.

Strain-specific colonization pattern of Rhizoctonia antagonists in the root system of sugar beet.
TLDR
The survival and colonization patterns of five different biocontrol agents against Rhizoctonia solani AG2-2IIIB in the rhizosphere of greenhouse-grown sugar beet plants were analysed in single and combined treatments to provide useful information on which combination of strains to test in larger biocOntrol experiments directed to applications.

In Vivo Study of Trichoderma-Pathogen-Plant Interactions, Using Constitutive and Inducible Green Fluorescent Protein Reporter Systems
TLDR
In situ interactions between gfp-tagged biocontrol strains of T. atroviride and soilborne plant pathogens that were grown in cocultures and on cucumber seeds by confocal scanning laser microscopy and fluorescence stereomicroscopy and green fluorescent protein expression under the control of host-inducible promoters was studied.

Salicylic acid prevents Trichoderma harzianum from entering the vascular system of roots.
TLDR
It is observed that, without the support of SA, plants were unable to prevent the arrival of the fungus in the vascular system and its spread into aerial parts, leading to later collapse. Expand
Ecological studies of the bio-inoculant Trichoderma hamatum LU592 in the root system of Pinus radiata.
TLDR
It was shown that total propagule counts do not always correlate with the amount of viable mycelium present in the root system, and it is proposed that the differentiation of mycelia from spores and root penetration is used as more accurate measures of fungal activity. Expand
Biological control of Fusarium oxysporum f. sp. phaseoli by Trichoderma harzianum and its use for common bean seed treatment
TLDR
Two isolates significantly reduced the Foxy incidence and enhanced seed germination, though less effective than the fungicide mixture (carboxin + thiram) and a principal component analysis indicated the importance of volatile metabolites in reducingFoxy incidence on common bean seeds. Expand
Induction and accumulation of PR proteins activityduring early stages of root colonizationby the mycoparasite Trichoderma harzianum strain T-203
TLDR
It is suggested that Trichoderma’'s association with roots reduce root disease through activation of the plant’s defence response throughactivation of the plants’ defence response. Expand
Suppression of Verticillium wilt in olive planting stocks by root-associated fluorescent Pseudomonas spp.
TLDR
root treatment of olive plants with selected P. fluorescens isolates during nursery propagation can help in the biocontrol of D V. dahliae in olive, and those bacteria counteracted the deleterious effects caused by the pathogen infection through enhancement of plant growth. Expand
