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

Chemical composition and antifungal properties of the essential oil and various extracts of Mikania scandens (L.) Willd
Shah Alam Siddiqui,Rafiquel Islam,Rezuanul Islam,Abu Hena Mostofa Jamal,Tanzima Parvin,Atiqur Rahman +5 more
TL;DR: In this paper, the antifungal potential of the essential oil and various extracts of Mikania scandens (L.) Willd. was assessed by GC-MS, and the results showed that the extracts displayed a great potential of antIFungal activity as a mycelial growth inhibition against the tested phytopathogenic fungi.

Two new diterpenoids from the endophytic fungus Trichoderma sp. Xy24 isolated from mangrove plant Xylocarpus granatum
Min Zhang,Jimei Liu,Jinlian Zhao,Ning Li,Ridao Chen,Kebo Xie,Wen-Jing Zhang,Keping Feng,Zheng Yan,Nan Wang,Jungui Dai +10 more
TL;DR: In this paper, two new harziane diterpenoids, named (9 R,10 R )-dihydro-harzianone (1 ) and harzianelactone (2 ), were isolated from the endophytic fungus Trichoderma sp. Xy24 by using various column chromatography techniques.

Ecological studies of the bio-inoculant Trichoderma hamatum LU592 in the root system of Pinus radiata
TL;DR: It was shown that total propagule counts do not always correlate with the amount of viable mycelium present in the root system, and it is proposed that the differentiation of mycelia from spores and root penetration is used as more accurate measures of fungal activity.

Biocontrol of Sclerotinia sclerotiorum infection of cabbage by Coniothyrium minitans and Trichoderma spp.
TL;DR: Nine fungal isolates tested for their ability to degrade sclerotia and reduce apothecial production and carpogenic infection of cabbage seedlings were tested in two bioassays, and C. minitans and T. hamatum was shown to have potential to control S. sclerOTiorum disease in cabbage.

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.
