Sustainable management of crop productivity and health necessitates improved understanding of the ways in which rhizosphere microbial populations interact with each other, with plant roots and their abiotic environment. In this study we examined the effects of different soils and cultivars, and the presence of a soil-borne fungal pathogen, Verticillium dahliae, on the fungal microbiome of the r...

Abstract Vascular wilt diseases caused by Verticillium dahliae Kleb. are difficult to control and lead increasing losses of many crops worldwide. It can cause disease on not only horticultural but also economically important such vegetables, legumes, forest trees, woody herbaceous plants. Reasons this situation various: (i) the specialization crop production resulted in accumulation pathogen so...

The ranges of infectious diseases and vectors are changing in altitude, along with shifts in plant communities and the retreat of alpine glaciers. Additionally, extreme weather events create conditions conducive to clusters of insect-, rodent- and water-borne diseases. Accelerating climate change carries profound threats for public health and society.

Biocontrol inoculants often show inconsistency in their efficacy at field scale and the reason for this remains often unclear. A high rhizosphere competence of inoculant strains is assumed to be a key factor for successful biocontrol effects as the biocontrol strain has to compete with the indigenous microbial community in the rhizosphere. It is known that many factors, among them plant species...

Epidemics of soil-borne plant disease are characterized by patchiness because of restricted dispersal of inoculum. The density of inoculum within disease patches depends on a sequence comprising local amplification during the parasitic phase followed by dispersal of inoculum by cultivation during the intercrop period. The mechanisms that control size, shape, and persistence have received very l...

Plants have evolved complex biochemical mechanisms to counter threats from insect herbivory. Recent research has revealed an important role of roots in plant responses to above ground herbivory (AGH). The involvement of roots is integral to plant resistance and tolerance mechanisms. Roots not only play an active role in plant defenses by acting as sites for biosynthesis of various toxins and bu...

Abstract In China, soil-borne viruses transmitted by the root parasite Polymyxa graminis have caused significant yield loss in winter wheat for many years. At present, it is believed that two main RNA viruses, namely yellow mosaic virus (WYMV) and Chinese (CWMV) are responsible such losses. The molecular characteristics infection processes of these been intensively investigated described substa...

application of antagonistic agents in the rhizosphere of plants is an important approach in control of soil-borne pathogens. establishment and persistence of biocontrol agents in the soil is a major concern in biological control. this study aimed to determine the effect of plant debris of oak forests on activity of pseudomonas fluorescens and trichoderma vierns against meloidogyne javanica in t...
