“…In an era where agricultural practices and climate change dynamically influence the landscape of crop diseases, the development of biovigilance platforms has become crucial for monitoring and managing the spread of phytopathogens. The fluctuations in pest and pathogen populations are driven by factors like agronomic practices such as the use of fungicides and resistant crop cultivars Kumar et al, 2023), natural air currents and those altered by climate change that may introduce new pathogens Velásquez et al, 2018) and human-facilitated transboundary dissemination via regional and international trade (Hulme, 2021). As such, early-warning systems have emerged as vital tools for prompt and precise disease management (Allen-Sader et al, 2019;Radici et al, 2021;Van der Heyden et al, 2021).…”

In the face of evolving agricultural practices and climate change, tools towards an integrated biovigilance platform to combat crop diseases, spore sampling, DNA diagnostics and predictive trajectory modelling were optimized. These tools revealed microbial dynamics and were validated by monitoring cereal rust fungal pathogens affecting wheat, oats, barley and rye across four growing seasons (2015–2018) in British Columbia and during the 2018 season in southern Alberta. ITS2 metabarcoding revealed disparity in aeromycobiota diversity and compositional structure across the Canadian Rocky Mountains, suggesting a barrier effect on air flow and pathogen dispersal. A novel bioinformatics classifier and curated cereal rust fungal ITS2 database, corroborated by real‐time PCR, enhanced the precision of cereal rust fungal species identification. Random Forest modelling identified crop and land‐use diversification as well as atmospheric pressure and moisture as key factors in rust distribution. As a valuable addition to explain observed differences and patterns in rust fungus distribution, trajectory HYSPLIT modelling tracked rust fungal urediniospores' northeastward dispersal from the Pacific Northwest towards southern British Columbia and Alberta, indicating multiple potential origins. Our Canadian case study exemplifies the power of an advanced biovigilance toolbox towards developing an early‐warning system for farmers to detect and mitigate impending disease outbreaks.

Endophytic microbes i.e. bacteria, fungi, and actinomycetes live inside the plant tissues without causing any harmful effect on them. Recently, research has been conducted on endophytic microbes to enhance agriculture and environmental sustainability. Endophytes stabilize a close association with their host, which leads to major changes in plant physiology. Endophytic microbes and pathogens use the same strategies for entering the host cell. This condition may create competition between the endophytes and the pathogen. Therefore, host plants develop strategies to allow the entry of specific microorganisms. Additionally, endophytic microorganisms may temper their own genetic structure to survive and avoid the host defence machinery. The plant-endophyte symbionts promote direct and indirect defences to host plants. This plays an essential role in modulating plant defences against various stresses, particularly biotic stress. In this minireview, we highlight the interaction of endophytic microbes with their host. As well as the role of endophytic microbes in the enhancement of plant defence systems.
