Trichoderma species--opportunistic, avirulent plant symbionts.
TLDR
Root colonization by Trichoderma spp.Abstract:
Trichoderma spp. are free-living fungi that are common in soil and root ecosystems. Recent discoveries show that they are opportunistic, avirulent plant symbionts, as well as being parasites of other fungi. At least some strains establish robust and long-lasting colonizations of root surfaces and penetrate into the epidermis and a few cells below this level. They produce or release a variety of compounds that induce localized or systemic resistance responses, and this explains their lack of pathogenicity to plants. These root-microorganism associations cause substantial changes to the plant proteome and metabolism. Plants are protected from numerous classes of plant pathogen by responses that are similar to systemic acquired resistance and rhizobacteria-induced systemic resistance. Root colonization by Trichoderma spp. also frequently enhances root growth and development, crop productivity, resistance to abiotic stresses and the uptake and use of nutrients.read more

A generic theoretical model for biological control of foliar plant diseases.
TL;DR: Qualitative analysis of the model showed that the rates of a BCA colonising diseased and/or healthy plant tissues and the time that the BCA remains active are two of the more important factors in determining the final outcome of a biocontrol system.

Trichoderma harzianum T-E5 significantly affects cucumber root exudates and fungal community in the cucumber rhizosphere
TL;DR: The modification of root exudates and the fungal com- munity by the application of BIO might account for the effective suppression of Fusarium wilt disease in cucumber plants.

TL;DR: Using a high-density oligonucleotide microarray, a number of genes probably involved in the transcriptional response of T. harzianum within the first hours of contact with tomato plant roots are defined, which may provide new insights into the mechanisms and roles of this fungus in the Trichoderma-plant interaction.

Peptaibiomics: Screening for Polypeptide Antibiotics (Peptaibiotics) from Plant-Protective Trichoderma Species
TL;DR: The results corroborate the hypothesis that peptaibiotics might contribute to the plant‐protective action of their fungal producers and point out that comparison ofpeptaibiotic sequences is of limited relevance in order to establish chemotaxonomic relationships among species of the genus Trichoderma.

Detection of viridiofungin A and other antifungal metabolites excreted by Trichoderma harzianum active against different plant pathogens
TL;DR: Contrary to several reports in the literature, VFA proved to be fungistatic rather than fungicidal, and neither VFA nor the other Trichoderma metabolites, such as 6PAP, F416 and F516, exhibited any antibacterial activity against Gram-positive and Gram-negative bacteria.

Systemic resistance induced by rhizosphere bacteria
TL;DR: Rhizobacteria-mediated induced systemic resistance (ISR) is effective under field conditions and offers a natural mechanism for biological control of plant disease.

Microbial interactions and biocontrol in the rhizosphere
TL;DR: Multiple microbial interactions involving bacteria and fungi in the rhizosphere are shown to provide enhanced biocontrol in many cases in comparison with biocOntrol agents used singly.

Mechanisms Employed by Trichoderma Species in the Biological Control of Plant Diseases: The History and Evolution of Current Concepts.
TL;DR: Past research indicates that the mechanisms are many and varied, even within the genus Trichoderma, and in order to make the most effective use of biocontrol agents for the control of plant diseases, it must understand how the agents work and what their limitations are.

TL;DR: The demonstration that PGPR strains release different volatile blends and that plant growth is stimulated by differences in these volatile blends establishes an additional function for volatile organic compounds as signaling molecules mediating plant–microbe interactions.
