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

TL;DR: Trichoderma strains showed variations to tolerate and grow under different doses of either NAPH, PHE or B[a]P, and increasing NAPH doses resulted on significant greater fungal growth inhibition than PHE doses.

Isolation, production and in vitro effects of the major secondary metabolite produced by Trichoderma species used for the control of grapevine trunk diseases
TL;DR: Results show that the presence of N. parvum and grapevine wood elicits the production of 6PP, suggesting that this metabolite is involved in Trichoderma–pathogen interactions on grapevine pruning wounds.

Microbial-mediated Induced Systemic Resistance in Plants
TL;DR: This chapter surveys the reports of recent investigations involving rhizospheric microorganisms especially plant growth-promoting rhizobacteria and arbuscular mycorrhizal fungi that could change the production and accumulation of plant pharmacologically active compounds.

Overview of mechanisms and uses of biopesticides
TL;DR: In China, some biopesticides currently being developed may be suitable alternatives to chemical pesticides such as Bacillus thuringiensis, Jinggangmycin, pyrethrins and brassinolide.

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.
