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 کامل3'-Hydroxylation of 4'-methoxyisoflavones by Fusarium oxysporum f. lycopersici.
3'-Hydroxylation of isoflavones by Fusarium oxysporum f. lycopersici mainly proceeds with 4'-methoxy-7-hydroxyderivatives; this reaction is used for quantitative conversion of 14C-labelled isoflavones.
متن کاملInhibitory Effect of Algal Extracts on Mycelial Growth of the Tomato-Wilt Pathogen, Fusarium oxysporum f. sp. lycopersici
The present study was undertaken to explore the inhibitory effect of cyanobacterial extracts of Nostoc commune FA-103 against the tomato-wilt pathogen, Fusarium oxysporum f. sp. lycopersici. In an optimal medium, cell growth, antifungal activity, and antifungal compound production could be increased 2.7-fold, 4.1-fold, and 13.4-fold, respectively. A crude algal extract had a similar effect as m...
متن کاملRed fluorescent protein (DsRed2) as a novel reporter in Fusarium oxysporum f. sp. lycopersici.
pAn-DsRed2 vector was constructed for constitutive cytoplasmic expression of the red fluorescent protein (DsRed2) under control of the glyceraldehyde-3-phosphate dehydrogenase gene promoter from Aspergillus nidulans. DsRed2-transformation of two Fusarium oxysporum f. sp. lycopersici strains pathogenic against tomato host resulted in bright red cytoplamic fluorescence of the fungus. The transfor...
