effect of successive watermelon plantings on Fusarium oxysporum and other microorganisms in soils suppressive and conducive to Fusarium wilt of watermelon
Phytopathology, 1993Co-Authors: R P Larkin, D L Hopkins, F N MartinAbstract:Five successive greenhouse plantings of watermelon cultivars Florida Giant (susceptible to Fusnrium wilt) and Crimson Sweet (moderately resistant and associated with soil suppressiveness) had different effects on the populations of Fusarium oxysporum f. sp. niveum, indigenous F. oxysporum, and various microorganism groups in the soil and on watermelon roots within four soils representing different suppressive and conducive conditions to Fusarium wilt. Pathogen populations were not affected by planting either cultivar in an induced suppressive soil developed by monoculture of Crimson Sweet or in a nonsuppressive Florida Giant monoculture soil [...]

In vitro antifungal activity of terpinen-4-ol, eugenol, carvone, 1,8-cineole (eucalyptol) and thymol against mycotoxigenic plant pathogens.
Food Additives and Contaminants, 2012Co-Authors: Caterina Morcia, Mauro Malnati, Valeria TerziAbstract:The aim of this study was to examine the effect of five natural molecules, taking part in the composition of essential oils, on ten different species of mycotoxigenic fungi involved in several plant diseases. The antifungal activities of terpinen-4-ol, eugenol, carvone, 1,8-cineole (eucalyptol) and thymol were observed in vitro on Fusarium subglutinans, Fusarium cerealis, Fusarium verticillioides, Fusarium proliferatum, Fusarium oxysporum, Fusarium sporotrichioides, Aspergillus tubingensis, Aspergillus carbonarius, Alternaria alternata, Penicillium. The natural molecules tested showed toxic effects on in vitro mycelium growth of all the fungal strains. The five oil components tested have different level of potency. The results obtained are encouraging for further studies directed to the investigation of in planta antifungal activities of these essential oils components.

in vitro antifungal activity of terpinen 4 ol eugenol carvone 1 8 cineole eucalyptol and thymol against mycotoxigenic plant pathogens
Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2011Co-Authors: Caterina Morcia, Mauro Malnati, Valeria TerziAbstract:The aim of this study was to examine the effect of five naturally occurring compounds from essential oils on 10 different species of mycotoxigenic fungi involved in several plant diseases. The antifungal activities of terpinen-4-ol, eugenol, carvone, 1,8-cineole (eucalyptol) and thymol were observed in vitro on Fusarium subglutinans, Fusarium cerealis, Fusarium verticillioides, Fusarium proliferatum, Fusarium oxysporum, Fusarium sporotrichioides, Aspergillus tubingensis, Aspergillus carbonarius, Alternaria alternata and Penicillium sp. The naturally occurring compounds tested showed toxic effects on in vitro mycelium growth of all fungal species but with different level of potency. The results are encouraging for further investigations of in planta antifungal activities of these essential oils components.

Brachypodium distachyon: a new pathosystem to study Fusarium head blight and other Fusarium diseases of wheat
BMC plant biology, 2011Co-Authors: Antoine Peraldi, Giovanni Beccari, A. Steed, Paul NicholsonAbstract:Fusarium species cause Fusarium head blight (FHB) and other important diseases of cereals. The causal agents produce trichothecene mycotoxins such as deoxynivalenol (DON). The dicotyledonous model species Arabidopsis thaliana has been used to study Fusarium-host interactions but it is not ideal for model-to-crop translation. Brachypodium distachyon (Bd) has been proposed as a new monocotyledonous model species for functional genomic studies in grass species. This study aims to assess the interaction between the most prevalent FHB-causing Fusarium species and Bd in order to develop and exploit Bd as a genetic model for FHB and other Fusarium diseases of wheat. The ability of Fusarium graminearum and Fusarium culmorum to infect a range of Bd tissues was examined in various bioassays which showed that both species can infect all Bd tissues examined, including intact foliar tissues. DON accumulated in infected spike tissues at levels similar to those of infected wheat spikes. Histological studies revealed details of infection, colonisation and host response and indicate that hair cells are important sites of infection. Susceptibility to Fusarium and DON was assessed in two Bd ecotypes and revealed variation in resistance between ecotypes. Bd exhibits characteristics of susceptibility highly similar to those of wheat, including susceptibility to spread of disease in the spikelets. Bd is the first reported plant species to allow successful infection on intact foliar tissues by FHB-causing Fusarium species. DON appears to function as a virulence factor in Bd as it does in wheat. Bd is proposed as a valuable model for undertaking studies of Fusarium head blight and other Fusarium diseases of wheat.

Development of PCR assays for the detection and differentiation of Fusarium sporotrichioides and Fusarium langsethiae.
FEMS microbiology letters, 2004Co-Authors: A.h. Wilson, D. Simpson, E. Chandler, P. Jennings, Paul NicholsonAbstract:Isolates of the type-A trichothecene producing Fusarium sporotrichioides and Fusarium langsethiae were grouped and differentiated in a phylogenetic tree using ITS sequence dissimilarity. An attempt was made to develop a PCR-based assay for the detection and differentiation of Fusarium sporotrichiodes from other Fusarium species using the 5′-region of the tri5 gene as a template. However, this assay was unable to differentiate, to a satisfactory level, between isolates of Fusarium sporotrichioides and Fusarium langsethiae, providing further genetic evidence for their close genetic relationship. A robust and repeatable PCR-assay was developed for the detection and differentiation of both species based on sequence determined from differentially amplified RAPD-PCR products. These assays were able to detect both species in samples of grain taken from the field.

mycoviruses in Fusarium species an update
Frontiers in Cellular and Infection Microbiology, 2019Co-Authors: Pengfei Li, Pallab Bhattacharjee, Shuangchao Wang, Lihang Zhang, Irfan AhmedAbstract:Fusarium is an important genus of plant pathogenic fungi, and is widely distributed in soil and associated with plants worldwide. The diversity of mycoviruses in Fusarium is increasing continuously due to the development and extensive use of state-of-the-art RNA deep sequencing techniques. To date, fully-sequenced mycoviruses have been reported in thirteen Fusarium species: Fusarium asiaticum, F. boothii, F. circinatum, F. coeruleum, F. globosum, F. graminearum, F. incarnatum, F. langsethiae, F. oxysporum, F. poae, F. pseudograminearum, F. solani, and F. virguliforme. Most Fusarium mycoviruses establish latent infections, but some mycoviruses such as Fusarium graminearum virus 1 (FgV1), Fusarium graminearum virus-ch9 (FgV-ch9), Fusarium graminearum hypovirus 2 (FgHV2), and Fusarium oxysporum f. sp. dianthi mycovirus 1 (FodV1) cause hypovirulence. Rapid advances in various omics technologies used to elucidate genes or biological processes can facilitate an improved understanding of mycovirus-host interactions. The review aims to illuminate the recent advances in studies of mycoviruses in Fusarium, including those related to diversity, molecular mechanisms of virus-host interaction. We also discuss the induction and suppression of RNA silencing including the role of RNAi components as an antiviral defense response.
