3'-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 کاملComparison of Fusarium oxysporum fsp lycopersici races 1, 2 and 3, and f.sp radicis lycopersici based on the sequences of fragments of the ribosomal DNA intergenic spacer region
Sequence analysis of genomic fragments from the intergenic spacer region from three isolates of Fusarium oxysporum fsp lycoperisci and fsp radicis lycopersici was carried out using the big dye terminator sequencing procedure. Two conditions of the DNA templates were also evaluated for their influence on the outcome of the terminator reaction. Results showed that sequencing using the PCR product...
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 کاملInduced resistance in tomato plants by IAA against Fusarium oxysporum lycopersici.
The phytohormone IAA (indol-3-acetic acid) was tested in vitro on growth of tomato wilt pathogen Fusarium oxysporum lycopersici. The hormone reduced spore germination, mycelial dry weight and protein content. Such reduction was matched with the elevation in the hormone concentration. The in vivo application of IAA to soil of the uninoculated plants (controls) improved growth and yielded longer ...
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...
