Sequencing soil microorganisms
Investigating the microbial community response to the introduction of non-endemic fungal bioinoculant in soil
Fungal bioinoculants have a huge potential in agriculture because they can help to increase crop yields and quality and allow a reduction in the application of chemicals.
While the effectiveness of bio-inoculants as bio-fertilisers or biopesticides is widely tested for crop yield and pathogens control, little is known about the effect of bioinoculants on microbial assemblages in the bulk soil of agroecosystems.
What happens to soil microbes when you introduce fungus to the soil?
ALIENinSoil will assess the impact of a fungal inoculum, the globally-used biofertiliser Trichoderma afroharzianum T22, on microbial assemblages of a model soil system.
A sudden artificial introduction of a fungal species in soil could create a substantial impact on the biodiversity of endemic microbial species and local community functions, as well as lead to changes in the food webs and nutrients availability.
Sequencing the DNA of soil microbes
This project will apply an innovative rapid metagenomic approach based on long-read Oxford Nanopore Technology to assess the effects of the fungal inoculum on soil microbial communities and functions in a laboratory-based microcosms experiment.
Oxford Nanopore sequencing has great potential to be used for real-time diagnostics in agricultural surveys and the development of indicators for monitoring soil biodiversity and functionality.
This project will use innovative and cutting-edge techniques to understand:
- to what extent the native microbial community richness and relative abundance is influenced by a fungal strain introduced to soil
- whether or not the keystone microbial taxa are resilient to the disturbance by the introduced fungus
- how far the bioinoculant impacts the functions of soil microorganisms.
This study will gain new in-depth knowledge and help to stimulate innovation in the field of soil bioinoculants and agriculture by way of competitive technology transfer.
The EU-funded ALIENinSoil project is investigating the effects of a fungus, widely used as biofertiliser, on microbial communities in soil.
Utilising Oxford Nanopore Technologies sequencing, which enables the direct, real-time analysis of long DNA fragments, the team will evaluate if the presence of this foreign fungus affects the growth and functioning of the native microorganisms.
