Molecular markers reflect differentiation of Fusarium oxysporum forma speciales on tomato and forma on eggplant

2013

Selective pressure induces pathogens to change their method of infection and, sometimes, causes species to become infectious. Pathogenic fungi must differentiate different morphological and physiological properties during the process of host specialization in their life cycle. In the present study, we conducted a genetic investigation and compared similarities within a generation of Fusarium oxysporum forma speciales (f. sp.) infecting tomato and forma (f.) infecting eggplants using selected ISSR and RAPD markers, two horticultural commodities belonging to the same taxon of the Solanaceae. Interestingly, genetic data showed that fungi belonging to F. oxysporum f. sp. infecting tomato have a…

Déterminisme du pouvoir protecteur de Fusarium oxysporum : recherche de gènes impliqués dans l'interaction protectrice avec la tomate

2007

Fusarium oxysporum is a common soil borne fungus, well represented in every type of soils, throughout the world. This species includes pathogenic strains inducing severe diseases in many crops and strains able to protect a plant against the infection by a pathogenic strain. The protective strains are not only non pathogenic strains isolated from suppressive soils but also pathogenic strains applied to a non host plant. The protective capacity of these strains is mainly based on mechanisms of competition and induced resistance of the plant The main objective of this work was to identify fungal genes involved in the protective capacity of these strains and associated to the elicitation of pla…

Fusarium oxysporum f. sp. cyclaminis: Identification of specific molecular markers for improved disease prevention

2014

Fusarium oxysporum is a well-known soil-borne and ubiquitous fungus. The species includes a high diversity of saprophytic and pathogenic populations. The phytopathogenic ones are subdivided into formae speciales according to their host specificity. The forma specialis cyclaminis (FoCy) is causing Fusarium wilt only on cyclamen. It causes damages during the entire production line and can raise more than 50 % losses. FoCy is considered as the more destructive pathogen on cyclamen. To achieve a better understanding of the disease and a more efficient and eco-friendly way of control, we aim at finding a specific molecular marker allowing for early detection and quantification of the pathogen an…

Les variétés de melon résistantes à la fusariose favorisent-elles dans leur rhizosphère la multiplication de souches pathogènes agressives ?

2012

http://prodinra.inra.fr/record/270428 SPE IPM CT2 (vu AB); Master; Au sein de l’espèce Fusarium oxysporum, champignon tellurique, il existe des souches pathogènes et des souches non pathogènes. Parmi les espèces phytopathogènes, il existe 120 formes spéciales, chacune caractéristique de l’espèce qu’elles infectent. La forme spéciale melonis colonise les racines du melon et s’installe dans le système vasculaire provoquant un jaunissement et un flétrissement des parties aériennes. Ces dix dernières années, malgré l’utilisation de variétés partiellement résistantes, on assiste à une augmentation de l’incidence et de la gravité de la fusariose du melon, les souches isolées étant de plus en plus…
