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

Root hydraulic conductance, aquaporins and plant growth promoting microorganisms: A revision
TL;DR: This review is intended to reflect the state of art in the knowledge of PGPM effects on plant water status and root hydraulic conductance, with special emphasis on the experimental data that prove or suggest an impact ofPGPM on root aquaporins under both normal and water limiting conditions.

Root-associated fungi of Arabidopsis thaliana and Microthlaspi perfoliatum
TL;DR: Root-associated fungi, with the focus on endophytic species, were isolated from healthy Arabidopsis thaliana and Microthlaspi perfoliatum plants collected at different locations in Germany, finding a large number of fungal taxa discovered with a small-scale approach.

TL;DR: The synthesis of these compounds implies that tomato plants are able to reuse the photorespiratory amino acids and ammonium for producing useful metabolites and reduce the pressure of photorespiration on plant metabolism, thus optimizing photosynthesis and growth.

Biological control of phytopathogenic fungi of vanilla through lytic action of Trichoderma species and Pseudomonas fluorescens.
TL;DR: The nature of Trichoderma antagonism is based on mycoparasitism (lysis) and appears to optimalize with contact between the mycelia, suggesting that the isolates can be used as biological control agents in vanilla plantations.

Bioactive polar natural compounds from garlic and onions
TL;DR: In this paper, a number of sapogenins and saponins from the wild onion species Allium elburzense, Allium hirtifolium, allium atroviolaceum, and Allium minutiflorum were identified.

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.
