The effect of the arbuscular mycorrhizal symbiosis (AM) varies in plant cultivars. In the present study, we tested whether wild-type, old and modern tomato cultivars differ in the parameters of the AM interaction. Moreover, the bioprotective effect of AM against the soilborne tomato pathogen Fusarium oxysporum f. sp. lycopersici (Fol) was tested in the(More)

Although most land plants are hosts for arbuscular mycorrhizal fungi (AMF), a small number of plant families are arbuscular mycorrhizal (AM) nonhosts. There are indications that strigolactone levels in root exudates of AM nonhost plants are lower than in AM host plants, and it has been shown that in the strigolactone-deficient rms1 mutant (ccd8) of the AM(More)
Gaeumannomyces graminis var. tritici (Ggt), a soil-borne fungal pathogen, causes take-all disease, one of the most important root disease of cereal plants such as barley, wheat and rye (Mathre 1992). These cereal plants, like 80% of all land plants, are able to form a symbiotic association with the soil-borne arbuscular mycorrhizal fungi (AMF) which can(More)
