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

The relationship between increased growth and resistance induced in plants by root colonizing microbes
Michal Shoresh,Gary E Harman +1 more
TL;DR: It is suggested that Trichoderma induces both increased growth, which is mediated by an increase in photosynthetic and respiratory rates, and systemic induced resistance, which may be mediated by different elicitors.

Burkholderia ambifaria and B. caribensis Promote Growth and Increase Yield in Grain Amaranth (Amaranthus cruentus and A. hypochondriacus) by Improving Plant Nitrogen Uptake
Fannie Isela Parra-Cota,Juan José Peña-Cabriales,Sergio de los Santos-Villalobos,Norma A. Martínez-Gallardo,John P. Délano-Frier +4 more
TL;DR: Strain of Burkholderia effectively promote growth and increase seed yields in grain amaranth and was particularly noticeable in plants grown in an infertile soil but also occurred in a well fertilized rich substrate.

TL;DR: It is demonstrated that the co-cultivation of plant beneficial fungi may represent an effective strategy to modulate the production of bioactive metabolites and possibly identify novel compounds.

The Stability of Biochar in the Environment
Andrew R. Zimmerman,Bin Gao +1 more
TL;DR: In this paper, the effects of biochar amendment on soil nutrient cycling, water balance, ecology, soil fertility and other associated benefits are investigated, and it has been shown that biochar, as a relatively refractory form of OM, can be used as a carbon sequestration tool.

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.
