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

Plant-growth-promoting rhizobacteria.
TL;DR: This review restricts itself to bacteria that are derived from and exert this effect on the root and generally designated as PGPR (plant-growth-promoting rhizobacteria), which can be direct or indirect in their effects on plant growth.

Biological control of soil-borne pathogens by fluorescent pseudomonads
Dieter Haas,Geneviève Défago +1 more
TL;DR: Biocontrol strains of fluorescent pseudomonads produce antifungal antibiotics, elicit induced systemic resistance in the host plant or interfere specifically with fungal pathogenicity factors during root colonization.

The rhizosphere microbiome: significance of plant beneficial, plant pathogenic, and human pathogenic microorganisms
TL;DR: The main functions of rhizosphere microorganisms and how they impact on health and disease are reviewed and several strategies to redirect or reshape the rhizospheric microbiome in favor of microorganisms that are beneficial to plant growth and health are highlighted.

Localized versus systemic effect of arbuscular mycorrhizal fungi on defence responses to Phytophthora infection in tomato plants
María J. Pozo,Christelle Cordier,Eliane Dumas-Gaudot,Silvio Gianinazzi,José M. Barea,Concepción Azcón-Aguilar +5 more
TL;DR: Evidence points to a combination of local and systemic mechanisms being responsible for this bioprotector effect of mycorrhizal symbiosis on tomato resistance to Phytophthora.

Concomitant induction of systemic resistance to Pseudomonas syringae pv. lachrymans in cucumber by Trichoderma asperellum (T-203) and accumulation of phytoalexins.
TL;DR: The results suggest that similar to beneficial rhizobacteria, T. asperellum may activate separate metabolic pathways in cucumber that are involved in plant signaling and biosynthesis, eventually leading to the systemic accumulation of phytoalexins.

Induction of terpenoid synthesis in cotton roots and control of Rhizoctonia solani by seed treatment with Trichoderma virens. [Erratum: 2003 Dec., v. 93, no. 12, p. 1606.]
TL;DR: It appears that induction of defense response, particularly terpenoid synthesis, in cotton roots by T. virens may be an important mechanism in the biological control by this fungus of R. solani-incited cotton seedling disease.
