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: In vitro applications of iso-HA inhibited the mycelium radial growth of Sclerotinia sclerotiorum and Rhizoctonia solani, and improved the germination of tomato seeds and induced disease resistance, suggesting that different forms of the same Trichoderma secondary metabolite have specific roles in the molecular mechanism regulating the Trichodma plant interaction.

Rhizosphere Microbiome Recruited from a Suppressive Compost Improves Plant Fitness and Increases Protection against Vascular Wilt Pathogens of Tomato.
TL;DR: Community-level analysis revealed differential microbial communities between the compost and the rhizosphere, suggesting a clear effect of the plant in the microbiome assembly, and shed light on the composition of a microbial consortium that could protect plants against the wilt pathogens of tomato and improve plant overall health.

Interaction between arbuscular mycorrhizal fungi and Trichoderma harzianum under conventional and low input fertilization field condition in melon crops: Growth response and Fusarium wilt biocontrol
TL;DR: Evaluated interactions between four arbuscular mycorrhizal fungi and the beneficial fungus Trichoderma harzianum, inoculated in a greenhouse nursery, with regard to their effects on melon crop growth under conventional and integrated-system field conditions, and the biocontrol effect against Fusarium wilt found the AMF-inoculated plants were effective in controlling Fusaria wilt.

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.
