Developing of Dna-marker to the Fusarium Oxysporum F. Sp. Lycopersici Resistance Genes of Tomato
Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici is a destructive disease of tomato crops worldwide. The use of resistant varieties is the best strategy for disease control. In the present study we analyze eight tomato lines and hybrids for Fusarium wilt disease resistance by polymerase chain reaction. Total genomic DNA was extracted from young leaves of three-week-old plants of to...
متن کاملOrigin of Race 3 of Fusarium oxysporum f. sp. lycopersici at a Single Site in California.
ABSTRACT Thirty-nine isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in a field in California 2 years after F. oxysporum f. sp. lycopersici race 3 was first observed at that location. These and other isolates of F. oxysporum f. sp. lycopersici were characterized by pathogenicity, race, and vegetative compatibility group (VCG). Of the 39 California isola...
متن کاملInteraction between Meloidogyne incognita and Agrobacterium tumefaciens or Fusarium oxysporum f. sp. lycopersici on Tomato.
Agrobacterium tumefaciens stimulated and Fusarium oxysporum f. sp. lycopersici inhibited development and reproduction of Meloidogyne incognita when applied to the opposite split root of tomato, Lycopersicon esculentum cv. Tropic, plants. The lowest rate of nematode reproduction occurred after 2,000 juveniles were applied and the fungus was present in the opposite split root. The effects of all ...
متن کاملEvaluation of Plant Extracts against Fusarium Oxysporum F. Sp. Lycopersici, Wilt Pathogen of Tomato
Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...
متن کاملMolecular phylogeny, pathogenicity and toxigenicity of Fusarium oxysporum f. sp. lycopersici
The present study aimed at the molecular characterization of pathogenic and non pathogenic F. oxysporum f. sp. lycopersici strains isolated from tomato. The causal agent isolated from symptomatic plants and soil samples was identified based on morphological and molecular analyses. Pathogenicity testing of 69 strains on five susceptible tomato varieties showed 45% of the strains were highly viru...
