We report 115 species of Fungi (Ascomycota, Basidiomycota) and Stramenopiles (Oomycota) as new to Sverdlovsk Region. Four are Russia (Boeremia heteromorpha, Chuppomyces cf. handelii, Nectria nigrescens, Passalora menispermi). 94% were identified only on alien plants in Ekaterinburg urban green plantations greenhouses. Pathogenic account for 92%, while several harmful plant pathogens.

The fungal pathogens Fusarium keratoplasticum and falciforme are responsible for the emerging infectious disease named sea turtle egg fusariosis (STEF). This affects all species throughout world, causing low hatching success mass mortalities. In this study, we investigated potential use of widely available easy-to-handle eggs invasive alien red-eared slider turtle, Trachemys scripta, as part an in vivo host model to improve our knowledge biological properties STEF. Specifically, performed experiments, which T. scripta were challenged with conidia F. isolated from diseased eggs. We found that pathogen could colonize develop similar signs those observed nature fulfill Koch’s postulates. showed high virulence (e.g., incidence, severity, success) its ability modify pH both surface culture media, confirming previously described models. These results support experimental studying characteristics STEF, thus providing valuable insights into mechanisms underlying emergence disease.

The diverse biotas of the world's mountains face a challenging future due to increasing threats like climate change, land-use and biological invasions, last being particularly understudied in these regions. Here we compile occurrence records for 717 alien vertebrate species distributed 2984 worldwide. We analyze their distribution, biogeographic origin, presence protected areas, drivers' explaining richness mountains. find that vertebrates most frequently recorded are birds (318 species) mammals (161 reported 2595 1518 globally, respectively. Palearctic, Nearctic, Australasian realms common recipients; Indo-Malay, Afrotropic frequent donors. Almost 50% studied also occur areas. Proxies anthropogenic impacts (e.g., higher road density or lower biodiversity intactness) mountains' physical characteristics elevation range roughness) explain distribution Importantly, magnitude invasions tropical could be underestimated sampling bias towards Northern Hemisphere Australia. Our large-scale assessment reveals advance worldwide urges attention minimize on exceptional mountain biotas.

Fungal diseases threaten the forest ecosystem, impacting tree health, productivity, and biodiversity. Conventional approaches to combating diseases, such as biological control or fungicides, often reach limits regarding efficacy, resistance, non-target organisms, environmental impact, enforcing alternative approaches. From an ecological standpoint, RNA interference (RNAi) mediated double-stranded (dsRNA)-based strategy can effectively manage fungal pathogens. The RNAi approach explicitly targets suppresses gene expression through a conserved regulatory mechanism. Recently, it has evolved be effective tool in promoting sustainable management bio-fungicides provide efficient eco-friendly disease alternatives using species-specific targeting, minimizing off-target effects. With accessible data on outbreaks, genomic resources, delivery systems, RNAi-based biofungicides promising for managing pathogens forests. However, concerns fate of molecules their potential impact organisms require extensive investigation case-to-case basis. current review critically evaluates feasibility against by delving into methods, persistence, aspects, cost-effectiveness, community acceptance, plausible future protection products.

Abstract Knowledge of the factors structuring populations pathogenic fungi is fundamental to disease management efforts and basic biology. High-quality short-read sequence data were obtained for 463 Macrophomina spp. isolates collected from 91 host plant species soil in 23 countries. Analyses revealed high diversity, admixture, equal mating type ratios suggesting on-going recombination. Although most tested could asymptomatically colonize strawberry, only a single phylogroup caused disease. In addition evidence specialization was discovered soybean, demonstrating this broad range pathogen contains phylogroups with cryptic specialization. Geography × isolate genotype associations weak, these frequently trafficked between regions. Re-analysis using genomic supported current boundaries, new molecular markers designed specifically identify each species. Contrary expectations, M. phaseolina should be considered both specialist generalist which meiosis can increase genetic diversity.
