Abstract:
Plant health and fitness widely depend on interactions with soil microorganisms. Some bacteria such as pseudomonads can inhibit pathogens by producing antibiotics, and controlling these bacteria could help improve plant fitness. In the present study, we tested whether plants induce changes in the antifungal activity of root-associated bacteria as a response to root pathogens. We grew barley plants in a split-root system with one side of the root system challenged by the pathogen Pythium ultimum and the other side inoculated with the biocontrol strain Pseudomonas fluorescens CHA0. We used repor

Abstract:
AbstractSoil-borne pathogens structure plant communities, shaping their diversity, and through these effects may mediate plant responses to climate change and disturbance. Little is known, however, about the environmental determinants of plant pathogen communities. Therefore, we explored the impact of climate gradients and anthropogenic disturbance on root-associated pathogens in grasslands. We examined the community structure of two pathogenic groups—fungal pathogens and oomycetes—in undisturbed and anthropogenically disturbed grasslands across a natural precipitation and temperature gradient

Biological control is an important process for sustainable plant production, and this trait is found in many plant-associated microbes.

Although these microbes have adapted to cohabit root tissues without causing disease, they are pathogenic to plant pathogens, including microbes, insects, and nemat

In examining beets with Rhizoctonia root rot in Michigan, over 50% of sampled roots had a second potential root rot pathogen, Rhizopus stolonifer.

Abstract:
Plant roots generate electrical currents and associated electrical fields as a consequence of electrogenic ion transport at the root surface. Here we demonstrate that the attraction of swimming zoospores of oomycete plant pathogens to plant roots is mediated in part by electrotaxis in natural root-generated electric fields. The zones of accumulation of anode- or cathode-seeking zoospores adjacent to intact and wounded root surfaces correlated with their in vitro electrotactic behavior. Manipulation of the root electrical field was reflected in changes in the pattern of zoospore accumulation an

Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root rot complex, and all commonly grown varieties are susceptible. Greenhouse methods to evaluate peas for resistance to Fusarium root rot resulted in inconsistent disease severity across varieties. In 2015, F. avenaceum infested field plots were more heavily damaged based on emergence and yield than F. solani infested plots, and opposite trends were observed in 2016. Differences

Phytophthora blight of peppers (Capsicum annuum), caused by the oomycete pathogen Phytophthora capsici, occurs in most regions where this crop is grown. The root and crown rot phase of the disease develops on plants in areas of the field where soil remains saturated with water after an irrigation or rainfall. Subsequent periods of soil saturation encourage further disease development.

Incidence of Charcoal rot, caused by the soil borne fungus Macrophomina phaseolina, may be increased in some crops by the addition of stress on the host caused by high salinity of soil or irrigation water and infection by plant pathogenic nematodes. Since both of these factors may be problematic in melon production in Arizona, studies were initiated to determine if higher salt concentrations of irrigation water and infection by Root-knot nematode (Meloidogyne incognita) may be involved in recent increased incidences of Charcoal rot of melon.

Mycorrhizal fungi also facilitate plant interactions with other soil microbes. These include pathogens, and bacteria that produce vitamins and protect against attack.

AMF can also provide protection against pathogens, making them valuable for biocontrol. Studies have shown that AMF can reduce the number of Meloidogyne galls and eggs while improving plant growth and nutrient absorption, potentially outperforming chemical pesticides.

Nitrous oxide (N2O) is a potent greenhouse gas with 300 times the warming potential of carbon dioxide (CO2). The majority of N2O release is attributed to agricultural soil emissions from fungal denitrification.

The paper presents the results of the appreciation of some tomato lines based on the resistance to the fungal pathogen Alternaria alternata. Culture filtrates (CF) of pathogen in the most cases did not significantly influence for the seed germination. A more obvious impact was manifested in the case of the root and the stem, the deviations from the control constituting -38.2…. -69.6% for the root and -40.7… -72.6% - for the stem. It was found that the greatest importance in the reaction to A. alternata isolates for seed germination had the genotypic factor, and for root and stem growth - the i

Abstract:
Strawberry is one of the most famous berry fruits growing in the last several years in Serbia. The total production was approximately 23,000 t in 2023, indicating that is less than in the previous years. In 2024, it was enough soil moisture only for initial plant development. After that period, mandatory irrigation was applied, especially in intensive crops such as strawberries. The occurrence of strawberry root rot disease occurs in years with high temperatures. Strawberry root rot is caused by Fusarium oxysporum, with high economic losses in greenhouse and open-field strawberry production. D

Abstract:
Take-all disease caused by Gaeumannomyces tritici, a fungal root pathogen, significantly impacts wheat production globally. Effective biocontrol for take-all is the buildup of a 2,4-diacetylphloroglucinol-producing Pseudomonas spp, which both antagonizes the pathogen and induces plant disease resistance. Previous work found that wheat genotypes vary in accumulating Pseudomonas spp in the rhizosphere, with those hosting more Pseudomonas spp being more resistant to disease. Here, we aim to identify plant genetic markers associated with this variation. In a greenhouse experiment, we grew two reco

Studies conducted in different soil and climatic zones have revealed differences in the composition and proportion of the main phytopathogenic fungi that cause root rot of agricultural plants. In the subtaiga zone, species of the genus Fusarium prevailed, and in the steppe zone, the phytopathogenic fungus Bipolaris sorokiniana prevailed. In the southern and northern forest-steppe, the ratio of these pathogens was approximately equal.

Abstract:
In intensive agriculture, harmful soilborne biotic agents, cause severe damage. These include both typical soilborne (clinical) major pathogens which destroy plants (e.g. Fusarium and Phytophthora pathogens), and subclinical ("minor") pathogens (e.g. Olpidium and Pythium). The latter cause growth retardation and yield decline. The objectives of this study were: (1) To study the behavior of clinical (major) and subclinical (minor) pathogens in plant growth substrate, with emphasis on zoosporic fungi, such as Pythium, Olipidium and Polymyxa.

Abstract:
Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds.

However, most soil bacteria cannot be cultivated using conventional techniques and therefore most of these compounds remain unexplored. The overall goal of this

Two species of bacteria, Cellulomonas uda and a Comamonas sp., were required for dentitrification. Celulomonas uda degraded cellulose and reduced nitrate to nitrite.
