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: Biological control practices need an integrative approach, and more knowledge than chemical control, and the use of new technology such as the biological disinfestation of soils.

Multifaceted beneficial effects of rhizosphere microorganisms on plant health and productivity
TL;DR: Plant growth promoting microorganisms and biological control agents are shown to possess secondary beneficial effects that would increase their usefulness as bio-inoculants, regardless of the need for their primary function.

Trichoderma: Systematics, the Sexual State, and Ecology
TL;DR: A chronology is presented that charts the development of a genus and species concept in Trichoderma, and a suggestion is made to modify the International Code of Botanical Nomenclature to enable adoption of a single generic name for Trichodma/Hypocrea.

Induction of Systemic Resistance in Plants by Biochar, a Soil-Applied Carbon Sequestering Agent
Yigal Elad,Dalia Rav David,Yael Meller Harel,Menahem Borenshtein,Hananel Ben Kalifa,A. Silber,Ellen R. Graber +6 more
TL;DR: It is found that soil-applied biochar induces systemic resistance to the foliar fungal pathogens Botrytis cinerea and Leveillula taurica on pepper and tomato and to the broad mite pest on pepper.

Michal Shoresh,Gary E. Harman +1 more
TL;DR: Up-regulation of carbohydrate metabolism and resistance responses may correspond to the enhanced growth response and induced resistance, respectively, conferred by the Trichoderma inoculation.

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.
