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

Trichoderma harzianum Enhances Antioxidant Defense of Tomato Seedlings and Resistance to Water Deficit
TL;DR: The hypothesis that enhanced resistance of colonized plants to water deficit is at least partly due to higher capacity to scavenge ROS and recycle oxidized ascorbate and glutathione is tested, a mechanism that is expected to enhance tolerance to abiotic and biotic stresses.

TL;DR: This review synthesizes current knowledge of fungal functional ecology, taxonomy and systematics and introduces a novel database offungal functional traits (FunFun), built to interface with other databases to explore and predict how fungalfunctional diversity varies by taxonomy, guild, and other evolutionary or ecological grouping variables.

TasHyd1, a new hydrophobin gene from the biocontrol agent Trichoderma asperellum, is involved in plant root colonization
Ada Viterbo,Ilan Chet +1 more
TL;DR: TasHyd1 deletion mutants had no significant reduction in in vitro mycoparasitic activity but were altered in their wettability and were severely impaired in root attachment and colonization, indicating that the protein is a new hydrophobin that contributes to Trichoderma interaction with the plant.

Epl1, the major secreted protein of Hypocrea atroviridis on glucose, is a member of a strongly conserved protein family comprising plant defense response elicitors
TL;DR: The results showed that epl1 transcript was present under all growth conditions tested, which included the carbon sources glucose, glycerol, l‐arabinose, d‐xylose, colloidal chitin and cell walls of the plant pathogen Rhizoctonia solani, and also plate confrontation assays with R. solani.

Deciphering endophyte behaviour: the link between endophyte biology and efficacious biological control agents.
TL;DR: This review highlights selected case studies of endophytes and discusses their lifestyles and behavioural traits, and discusses how these factors contribute towards their effectiveness as biological control agents.

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.
