... Corynespora cassiicola is the causal agent of target spot of several cultivated species, among which cucumber is highlighted for frequent reports of yield losses under greenhouse conditions. Given the difficulties managing this disease due to the lack of information about the resistance of cucumber cultivars, the aim of the present study was to evaluate the response of ten cucumber cultivars to C. ...

Abstract:
... Small RNA (sRNA)-mediated RNA interference (RNAi) is a regulatory mechanism conserved in almost all eukaryotes. sRNAs play a critical role in host pathogen interactions either endogenously or by traveling between the interacting organisms and inducing ‘cross-Kingdom RNAi’ in the counterparty. Cross-kingdom RNAi is the mechanistic basis of host-induced gene silencing (HIGS), which relies on genetic ...

Abstract:
... Among wood diseases, esca complex has increased over the last decades around Europe, and there are no chemical solutions that can limit its spread in vineyards. During a 7-year trial in 3 vineyards, half of the surface was sprayed every season with a solution of Trichoderma asperellum and Trichoderma gamsii at the phenological stage of bleeding, and half of the vineyard remained untreated. During ...

Abstract:
... Esca disease and Botryosphaeria dieback are currently considered as serious grapevine diseases which affect vineyard health and induce economic losses. Both of these trunk diseases (GTDs) are caused by a complex of pathogens, and foliar expression is influenced by several factors, including environmental factors such as water stress. To manage water stress in some vine areas, culture practice base ...
... The filamentous fungus Fusarium oxysporum is a soilborne pathogen of many cultivated species and an opportunistic pathogen of humans. F. oxysporum f. sp. matthiolae is one of three formae speciales that are pathogenic to crucifers, including Arabidopsis thaliana, a premier model for plant molecular biology and genetics. Here, we report a genome assembly of F. oxysporum f. sp. matthiolae strain PHW ...

Abstract:
... BACKGROUND AND AIMS: Ozonated water has been used in vineyards to reduce the use of pesticides because of its presumed efficacy in the control of fungal diseases and the absence of residues. The aim of this study was to evaluate the effect of ozonated water treatments on the composition of grapes. METHODS AND RESULTS: Ozonated water was applied to grapevines of Vitis vinifera cv. Cabernet Sauvigno ...
... Barley grain infected with fungi of the genus Fusarium was analyzed with the use of a machine vision system. Mold-affected, black-tipped and healthy kernels were viewed under polarized light and non-polarized light as the reference method, and the resulting images were compared. Texture attributes were calculated in selected regions of interest (ROIs) and used in statistical modeling. The results ...
... In this work, we rechecked, using species-specific Loop mediated isothermal AMPlification (LAMP) diagnostic assays followed by sequencing of fungal isolates at the beta-2-tubulin (tub2) gene region, a historical and never confirmed report of Dothistroma needle blight (DNB) in the introduced Monterey pine (Pinus radiata D. Don) in the mountains in the extreme tip of southern Italy. The report dates ...
... Early leaf spot (ELS) and late leaf spot (LLS) are major fungal diseases of peanut that can severely reduce yield and quality. Development of acceptable genetic resistance has been difficult due to a strong environmental component and many major and minor QTLs. Resistance genes (R-genes) are an important component of plant immune system and have been identified in peanut. Association of specific R ...
... The aim of the research was to develop an innovative technique in the seed production of red clover. The research was carried out in 2013–2016, in Felin (51°22′ N, 22°65′ E), in a dependent arrangement (split-split-plot) in four replications. The first order factor was the use of an attractant: (1) control object, with pure water spraying, (2) attractant used in the 60 BBCH phase, (3) attractant a ...

Abstract:
... A quantitative PCR (qPCR)-assay was developed to detect airborne inoculum of Nothopassalora personata, causal agent of late leaf spot (LLS) on peanut, collected with a modified impaction spore trap. The qPCR assay was able to consistently detect as few as 10 spores with purified DNA and 25 spores based on crude DNA extraction from rods. In 2019, two spore traps were placed in two peanut fields wit ...

Abstract:
... Tree bark is widely used in traditional medicine in southern Africa. The growing demand for medicinal bark requires scientifically sound harvest systems for sustainable use. A conceptual framework and decision matrix are presented to aid forest managers in selecting the most appropriate system for the sustainable harvesting of particular species. The conceptual framework is based on the results of ...

Abstract:
... Pathogenic fungi cause enormous losses to fruits, and ethylene (ET) is associated with disease development in fruit crops. In this study, ET production of several fungal pathogens was enhanced by light, probably through the free radicals produced by photochemical reactions. Real-time gas analysis showed a sharp increase in ET production when fungal cultures were moved from dark-to-light (DTL). Sim ...
... Ambrosia beetles exhibit broad host ranges but a narrow preference based on the condition of the host. Tissues infected by pathogens or containing ethanol can facilitate attacks by ambrosia beetles, although it still remains unclear how these factors interact. The present study aimed to examine how (i) chestnut logs infected with the fungal pathogen Cryphonectria parasitica and treated with ethano ...

Abstract:
... Even though Fusarium is an important genus of fungi, both phytopathogenic and toxigenic, that infects various cereals worldwide, the existing methods of Fusarium spp. suppression in agroecosystems are not sufficiently operative. On the other hand, being tightly linked to plant residues it its life cycle, Fusarium spp. could be expected to interact with detrital food webs. Over the past 30 years, 2 ...

A comparative study of the basic structural components of productivity, the most important economically valuable traits, and grain quality has been carried out using collection and standard cultivars of this crop as well as the standard cultivars of spring triticale (cv ...
... Drought has been assumed as a predisposing factor in the decline caused by Phytophthora cinnamomi on Mediterranean Quercus forests, enhancing cork oak susceptibility to the root infection. However, P. cinnamomi outbreaks appear associated to waterlogged soils, with infections being particularly successful when soil moisture content fluctuates from flooding to water deficiency. We obtained cork oak ...
