Journal ArticleDOI
Ecological functions of Trichoderma spp. and their secondary metabolites in the rhizosphere: interactions with plants.
TL;DR: The present review describes the most recent advances in understanding the ecological functions of Trichodermaspp.
Journal ArticleDOI
Organic and mineral fertilization, respectively, increase and decrease the development of external mycelium of arbuscular mycorrhizal fungi in a long-term field experiment.
TL;DR: Measurement of WCFAs in soil is a useful research tool for providing information in the characterization of soil microflora, indicating that the measurement of AMF mycelium were not distorted by erroneous involvement of hyphae of saprotrophs.
Journal ArticleDOI
Suppression of the biocontrol agent trichoderma harzianum by mycelium of the arbuscular mycorrhizal fungus glomus intraradices in root-free soil
TL;DR: It seemed that growth of and phosphorus uptake by the external mycelium of G. intraradices were not affected by the antagonistic fungus T. harzianum, and the use of a compartmented growth system with root-free soil compartments suggests that nutrient competition is a likely means of interaction.
Journal ArticleDOI
Soil fungal community structure along a soil health gradient in pea fields examined using deep amplicon sequencing
TL;DR: The fungal communities in the nine soils were strongly dominated by Ascomycota and Basidiomycota, and no correlation was found between the disease severity index and the abundance of some of the other fungi and oomycetes normally considered as root pathogens in pea.
Journal ArticleDOI
Bacterial populations associated with mycelium of the arbuscular mycorrhizal fungus Glomus intraradices.
TL;DR: Large differences in bacterial community structure were observed between rhizosphere soil, root-free soil/sand and washed sand extract, whereas major differences between mycorrhizal and non-mycorrhIZal treatments were observed for a few bacterial species only.
