Muld on suurim süsiniku reservuaar maismaa ökosüsteemides ja sealt eralduvad kasvuhoonegaasid annavad tugeva panuse kliima soojenemisse. Antud projekti käigus kasutatakse kõige uudsemaid taksonoomilise ja funktsionaalsuse määramise meetodeid – triipkoodistamise ja metatranskriptoomikat – et tuvastada mullamikroobide mõju mulla süsinikubilansile ja kasvuhoonegaaside eritumisele ja selle sõltuvust mulla toitainete sisaldusest ja pH-st.
Carbon emissions from soils contribute strongly to climate warming. The link between soil fertility and soil microbiome is well established, but soil microbial feedback to climate change is unclear. This project uses metatranscriptomics and state-of-the-art identification methods to evaluate the shifts in soil microbial communities and their activities related to C and N cycling along soil fertility gradients at different levels of soil pH. We will also test the effects of changes in plant community composition and substrate quality on these shifts along the soil fertility gradient. We will consider a wide range of genes involved in C and N cycling, which provide us better understanding of plant-soil-climate interactions and the consequential effects on soil microbiome contribution to greenhouse gas emissions and climate change.
