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

Selection of high temperature and salinity tolerant Trichoderma isolates with antagonistic activity against Sclerotium rolfsii
Sowmya Poosapati,Prasad Durga Ravulapalli,Navaneetha Tippirishetty,Dinesh Kumar Vishwanathaswamy,Sarada Chunduri +4 more
TL;DR: The study identified a potential thermotolerant and saline tolerant strain of Trichoderma, TaDOR673 that could be used as potential bioagent in stressed soils.

Assisted phytoextraction of heavy metals: compost and Trichoderma effects on giant reed (Arundo donax L.) uptake and soil N-cycle microflora
Nunzio Fiorentino,Massimo Fagnano,Paola Adamo,Adriana Impagliazzo,Mauro Mori,Olimpia Pepe,Valeria Ventorino,Astolfo Zoina +7 more
TL;DR: The suitability of the giant reed for assisted-phytoremedation with the use of compost fertilisation and T. harzianum inoculation was proved and Nitrifying bacteria was shown to be a useful tool to biomonitor soil quality.

Effect of Trichoderma on Seed Germination and Seedling Parameters of Chili
M Asaduzzaman,MJ Alam,MM Islam +2 more
TL;DR: Seed treatment with T. harzianum IMI-3924332 can be useful to enhance the germination of chili seeds as well as reduce to delayed germination, according to the vigour index values.

Role of plant growth regulators and a saprobic fungus in enhancement of metal phytoextraction potential and stress alleviation in pearl millet.
TL;DR: Approximate results show that application of crude PGR in combination with other phytoextraction assistants can increase biomass production as well as multi-metal accumulation in plants, however, the biochemical properties of the plant depend on the level of TSW stress in the soil treatment aswell as the type of phy toExtraction assistants.

Mechanisms and characterization of Trichoderma longibrachiatum T6 in suppressing nematodes (Heterodera avenae) in wheat
TL;DR: It is suggested that TL6 is potentially an effective bio-control agent for H. avenae because of the direct parasitic and lethal effect of TL6 on the eggs and J2s activity, and the induced defense response in wheat plants together.

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.
