“…For example, 'game theory' and the 'Lotka-Volterra model' can be expanded to describe microbial interactions related to pathogen colonization or extinction to predict disease emergence 166 . Statistical models can provide information on the direct and indirect impacts of environmental and biotic variables on disease incidence [167][168][169] , whereas dynamic network models allow incorporation of several aspects of disease epidemiology including molecular and cellular reactions, plant-vector-pathogen interactions, species interactions in the microbiome as well as international trade and social networks (reviewed elsewhere 170 ). Predictions of disease risks based on combinations of aerobiological models for inoculum transmission and crop-growth models offer a framework to quantify the impact of future climates on the risk of disease occurrence and spread 171,172 .…”

Plant disease outbreaks pose significant risks to global food security and environmental sustainability worldwide, and result in the loss of primary productivity and biodiversity that negatively impact the environmental and socio-economic conditions of affected regions. Climate change further increases outbreak risks by altering pathogen evolution and host–pathogen interactions and facilitating the emergence of new pathogenic strains. Pathogen range can shift, increasing the spread of plant diseases in new areas. In this Review, we examine how plant disease pressures are likely to change under future climate scenarios and how these changes will relate to plant productivity in natural and agricultural ecosystems. We explore current and future impacts of climate change on pathogen biogeography, disease incidence and severity, and their effects on natural ecosystems, agriculture and food production. We propose that amendment of the current conceptual framework and incorporation of eco-evolutionary theories into research could improve our mechanistic understanding and prediction of pathogen spread in future climates, to mitigate the future risk of disease outbreaks. We highlight the need for a science–policy interface that works closely with relevant intergovernmental organizations to provide effective monitoring and management of plant disease under future climate scenarios, to ensure long-term food and nutrient security and sustainability of natural ecosystems.

“…Most of these studies have used next-generation sequencing of microbial marker genes like 16S rRNA for bacteria and the nuclear ribosomal internal transcribed spacer (ITS) region for fungi, while others have used shotgun metagenomics sequencing, where all DNA present in an environmental sample is sequenced. Currently, there are a large number of studies on rhizosphere fungal communities in agricultural crops such as Arabidopsis, Arabis alpina , poplar, and sugarcane, and it has been shown that the phyla Ascomycota, Basidiomycota, and less Zygomycota, and Glomeromycota dominate the root mycobiota (de Souza et al 2016; Bergelson et al 209; Liu et al 2023). The high representation of selected fungal phyla in the rhizosphere of different plants suggests that members of these phyla are competitive and adaptable colonizers in various soil types and locations (Boddy and Hiscox 2016; Mueller et al 2020).…”

Chernevaya taiga in Western Siberia, Russia, is a special environment with fertile soil, extraordinarily high herbaceous plant sizes, and incredibly quick rates of plant residues breakdown. We postulated that a unique rhizospheric fungal community would be created when growing crops on chernevaya soil, which has never been used for agriculture. These may be the source for the novel effective biostimulator and biocontrol fungal agents for modern agriculture. In this study, we analyzed the fungal communities in the rhizosphere of spring wheat and radish cultivated in greenhouse experiments on chernevaya and control soils using high-throughput ITS sequencing. Additionally reprehensive fungal strains were isolated and examined for the stimulation of wheat seedlings growth. The research shows that Ascomycota and Mortierellomycota were the most abundant phyla in the rhizospheric fungal community, mainly composed of Mortierella species. The control soils were abundant in Mucoromycota, represented mostly by Mucor and Umbelopsis. Potentially plant-pathogenic fungi Fusarium and Oidiodendron were found only in the rhizosphere of crops grown in the control soil. Whereas plants grown on chernevaya soil have a wide variety of possible biocontrol fungi. Novel fungal isolates demonstrated stimulating effect on the growth and biomass accumulation of wheat seedlings. The findings of the study imply that the creation of biorational products for crop growth and protection may depend on the taxonomic composition analysis of the rhizospheric mycobiota of the crops growing on the soil with the unique characteristics.
