Abstract

Climatic variations and modern agricultural technologies change the fungi distribution area ofthe genus Fusarium Link., and lead to their dominance in pathocomplexes. The parasitic activity of fusarium fungi and localization of their ecological niches is determined by the activity of constantly expanding environmental and anthropogenic drivers. The fundamental niches of Fusarium pathogens are characterized by complexity and multidimensionality. Realized ecological niches change in space and time at the ontogenesis different stages of pathogenic micromycetes; the same species shows high heterogeneity in implementing its fundamental niche depending on environmental factors and the host plant species. The overlap level of ecological niches and interspecific relationships largely determine the species composition of the pathogenic complex of adiscrete phytocenosis.

Highlights

Fungi of the genus Fusarium Link. are permanent soil inhabitants and cause widespread and harmful diseases of agricultural and wild plant species [1]
Realized ecological niches change in space and time at the ontogenesis different stages of pathogenic micromycetes; the same species shows high heterogeneity in implementing its fundamental niche depending on environmental factors and the host plant species
To analyze the ecological niches of pathogenic micromycetes, we have proposed an evolutionary-ecological classification according to which the phytopathogen ecological niches can be divided into specific and non-specific ones

Summary

Introduction

Fungi of the genus Fusarium Link. are permanent soil inhabitants and cause widespread and harmful diseases of agricultural and wild plant species [1]. Are permanent soil inhabitants and cause widespread and harmful diseases of agricultural and wild plant species [1]. - a causative agent of tracheomycotic wilt and root rot of many plant species, as well producers of dangerous mycotoxins as F. graminearum Schwabe, F. culmorum (W.G. Sm.) Sacc., F. moniliforme Sheld., F. solani (Mart.) App. et Wr., F. sporotrichioides Sherb., etc. The parasitic activity of phytopathogens and localization of their ecological niches are determined by environmental and anthropogenic drivers, their list is constantly expanding [3, 8 ,9]. In this regard, a detailed analysis of the structure of fundamental ecological niches and mechanisms of their implementation by fungi of the genus Fusarium has become highly relevant
