Biological Control of Plant-Parasitic Nematodes by Filamentous Fungi Inducers of Resistance: Trichoderma, Mycorrhizal and Endophytic Fungi

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: May 25, 2020

Plant-parasitic-nematodes represent a major threat to the agricultural production of different crops worldwide. Due high toxicity chemical nematicides, it is necessary develop new control strategies against nematodes. In this respect, filamentous fungi can be an interesting biocontrol alternative. The genus Trichoderma, mycorrhizal and endophytic are main groups studied used as biological agents (BCAs) nematodes resistance inducers. They able reduce damage caused by plant-parasitic directly parasitism, antibiosis, paralysis lytic enzymes. But they also minimise harm space resource-competition, providing higher nutrient water uptake plant, or modifying root morphology, and/or rhizosphere interactions, that constitutes advantage for plant-growth. Besides, induce activating hormone-mediated (salicylic jasmonic acid, strigolactones among others) plant-defence mechanisms. Additionally, alteration transport defence components through plant synthesis secondary metabolites enzymes contribute enhancing defences. Therefore, use mentioned BCAs promising durable strategy in agriculture

In honor of John Bissett: authoritative guidelines on molecular identification of Trichoderma

Fungal Diversity, Journal Year: 2021, Volume and Issue: 107(1), P. 1 - 69

Published: Feb. 5, 2021

Abstract Modern taxonomy has developed towards the establishment of global authoritative lists species that assume standardized principles recognition, at least in a given taxonomic group. However, fungi, delimitation is frequently subjective because it depends on choice concept and criteria selected by taxonomist. Contrary to it, identification fungal expected be accurate precise should predict properties are required for applications or relevant pathology. The industrial plant-beneficial fungi from genus Trichoderma (Hypocreales) offer suitable model address this collision between identification. A few decades ago, diversity was limited dozen species. introduction molecular evolutionary methods resulted exponential expansion taxonomy, with up 50 new recognized per year. Here, we have reviewed genus-wide compiled complete inventory all DNA barcoding material deposited public databases (the available website International Subcommission Taxonomy www.trichoderma.info ). Among 375 valid names as July 2020, 361 (96%) been cultivated vitro barcoded. Thus, protocol requires analysis three barcodes (ITS, tef1 , rpb2 ), supported online tools www.trichokey.info . We then used whole-genome sequenced (WGS) strains provide versatile practical examples identification, reveal shortcomings, discuss possible ambiguities. Based example, study shows why an intricate laborious task background mycology, biological skills, training analysis, knowledge literature. in-depth discussion concepts applied conclude these particularly implementation polyphasic approach first introduced John Bissett (1948–2020), whose work inspired current study. also propose regulatory unifying role international commissions particular groups. An important outcome demonstration urgent need cooperation researchers get prepared efficient use upcoming wave genomic data.

Trichoderma as biocontrol agent against pests: New uses for a mycoparasite

Biological Control, Journal Year: 2021, Volume and Issue: 159, P. 104634 - 104634

Published: April 22, 2021

Insects are the main pest in agricultural systems, causing significant losses crop productivity and storage. During last decades control of insects has been carried out through uncontrolled massive use chemical insecticides, very harmful to environment health, which requires development new efficient safe alternatives. Numerous fungal species have described as entomopathogens insect pests, well plant endophytic fungi. In this sense, Trichoderma is a genus filamentous fungi widely studied used biocontrol agent agriculture on pathogenic due its ability parasitize them (mycoparasitism), among other mechanisms action. recent years, possibility using for considered, both directly indirectly. The studies date reported that capable controlling parasitism production insecticidal secondary metabolites, antifeedant compounds repellent metabolites. And indirectly activation systemic defensive responses, attraction natural enemies or insect-symbiotic microorganisms. Therefore, not only effective against pathogens, but also representing future alternative sustainable agriculture.

Trichoderma Species: Our Best Fungal Allies in the Biocontrol of Plant Diseases—A Review

Plants, Journal Year: 2023, Volume and Issue: 12(3), P. 432 - 432

Published: Jan. 17, 2023

Biocontrol agents (BCA) have been an important tool in agriculture to prevent crop losses due plant pathogens infections and increase food production globally, diminishing the necessity for chemical pesticides fertilizers offering a more sustainable environmentally friendly option. Fungi from genus Trichoderma are among most used studied microorganisms as BCA variety of biocontrol traits, such parasitism, antibiosis, secondary metabolites (SM) production, defense system induction. Several species well-known mycoparasites. However, some those can antagonize other organisms nematodes pests, making this fungus very versatile BCA. has part innovative bioformulations, either just or combination with plant-beneficial microbes, growth-promoting bacteria (PGPB). Here, we review recent literature regarding studies about six species, T. atroviride, harzianum, asperellum, virens, longibrachiatum, viride, highlighting their traits use these fungal genera Trichoderma-based formulations control diseases, importance substitute fertilizers.
