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

Mechanisms of the IAA and ACC-deaminase producing strain of Trichoderma longibrachiatum T6 in enhancing wheat seedling tolerance to NaCl stress
TL;DR: The results indicate that the strain of TL-6 effectively promoted wheat growth and enhanced plant tolerance to NaCl stress through the increased ACC-deaminase activity and IAA production inTL-6 stain that modulate the IAA and ethylene synthesis, and regulate the transcriptional levels of IAAand ethylene syntheses expression in wheat seedling roots under salt stress.

Soil Fungal Resources in Annual Cropping Systems and Their Potential for Management
Walid Ellouze,Ahmad Esmaeili Taheri,Luke D. Bainard,Chao Yang,Navid Bazghaleh,Adriana Navarro-Borrell,Keith Hanson,Chantal Hamel +7 more
TL;DR: This review highlights the functional groups of fungi that play key roles in agricultural ecosystems, examines the influence of agronomic practices on these fungi, and proposes ways to improve the management and contribution of soil fungi to annual cropping systems.

Multifaceted Plant-Associated Microbes and Their Mechanisms Diminish the Concept of Direct and Indirect PGPRs
TL;DR: The examples discussed in this chapter dilute the boundary between direct and indirect and raise questions for the researchers to gather more knowledge on the intricately woven relationship and functions of the metabolites and mechanisms as a whole.

Calcium-mediated perception and defense responses activated in plant cells by metabolite mixtures secreted by the biocontrol fungus Trichoderma atroviride
Lorella Navazio,Barbara Baldan,Roberto Moscatiello,Anna Zuppini,Sheridan L. Woo,Paola Mariani,Matteo Lorito +6 more
TL;DR: New insights are provided into the mechanism of interaction between Trichoderma and plants, indicating that secreted fungal molecules are sensed by plant cells through intracellular Ca2+ changes.

Cellulase from Trichoderma harzianum interacts with roots and triggers induced systemic resistance to foliar disease in maize
Kandasamy Saravanakumar,Lili Fan,Kehe Fu,Chuanjin Yu,Meng Wang,Hai Xia,Jianan Sun,Yaqian Li,Jie Chen +8 more
TL;DR: It is demonstrated that functional Thph1 and Thph2 may be required in T. harzianum to activate ISR in maize and the genes related to the jasmonate/ethylene signaling pathway were up-regulated in the wild-type maize strain.

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.
