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

Bioactivity of endophytic Trichoderma fungal species from the plant family Cupressaceae
TL;DR: The above findings show for the first time the presence of T. atroviride and T. koningii as endophytic fungi in Cupressaceae plants and more importantly, the Trichoderma isolates demonstrate significant bioactivity that could be used in future for agrochemical/drug discovery and pathogen biocontrol.

A systems-wide comparison of red rice (Oryza longistaminata) tissues identifies rhizome specific genes and proteins that are targets for cultivated rice improvement
Ruifeng He,Fernanda Salvato,Fernanda Salvato,Jeong-Jin Park,Min-Jeong Kim,William Nelson,Tiago Santana Balbuena,Tiago Santana Balbuena,Mark R. Willer,John A. Crow,Greg D. May,Carol Soderlund,Jay J. Thelen,David R. Gang +13 more
TL;DR: The presence of M. oryzae gene transcripts at a high level in apparently healthy plants suggests that red rice is resistant to this pathogen, and may be able to provide genes to cultivated rice that will enable resistance to rice blast disease.

Biological control of avocado white root rot with combined applications of Trichoderma spp. and rhizobacteria
David Ruano-Rosa,Francisco M. Cazorla,Nuria Bonilla,Rosa Martín-Pérez,A. de Vicente,C. J. López-Herrera +5 more
TL;DR: Compatibility between the combined Trichoderma applications and the bacterial strains was observed and these combinations significantly improved the control of R. necatrix during the in vitro experiments.

In vitro biocontrol analysis of Alternaria alternata (Fr.) Keissler under different environmental conditions.
F. Sempere,M. P. Santamarina +1 more
TL;DR: Biocontrol was governed by different mechanisms such as competition for space and nutrients, mycoparasitism, and possible antibiosis, and temperature and water activity significantly influenced fungal growth rate.

How a Mycoparasite Employs G-Protein Signaling: Using the Example of Trichoderma
Markus Omann,Susanne Zeilinger +1 more
TL;DR: Components of the G-protein signaling machinery such as Gα subunits and G- protein-coupled receptors were recently shown to play crucial roles in Trichoderma mycoparasitism as they govern processes such as the production of extracellular cell wall lytic enzymes, the secretion of antifungal metabolites, and the formation of infection structures.

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.
