Production and Characterization of Exopolygalacturonase from Fusarium Oxysporum F. Sp. Lycopersici
Polygalacturonases (PGs) are pectinolytic enzymes with wide industrial applications. The demand for the enzyme and its producing organism is rapidly increasing. Enzymes from filamentous fungi have been subject to vast number of studies due to their functional role in the organism as well as their advantage as models for enzyme production and their characteristics. The objective of the study was...
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 کاملارزیابی توان استرپتومیستهای ریزوسفر گوجهفرنگی در کنترل قارچ بیمارگر Fusarium oxysporum f.sp. radicis-lycopersici
پوسیدگی ریشه و طوقه گوجهفرنگی با عامل Fusarium oxysporum f.sp. radicis-lycopersici (FORL) یکی از بیماری‌های مهم خاکزاد گوجهفرنگی بهحساب میآید. در این پژوهش 740 جدایه اکتینوباکتری از مزارع گوجهفرنگی مناطق مختلف استانهای فارس و البرز جمعآوری گردید. آزمونهای آنزیمی انجام گرفته حاکی از تولید آنزیم پروتئاز و توانایی تولید سیدروفور در تمامی جدایه‌ها بود. محیط کشت فیلتر شده جدایه UTS49 بهع...
متن کاملInteractions in the tomato rhizosphere of two Pseudomonas biocontrol strains with the phytopathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici.
The fungus Fusarium oxysporum f. sp. radicis-lycopersici causes foot and root rot of tomato plants, which can be controlled by the bacteria Pseudomonas fluorescens WCS365 and P. chlororaphis PCL1391. Induced systemic resistance is thought to be involved in biocontrol by P. fluorescens WCS365. The antifungal metabolite phenazine-1-carboxamide (PCN), as well as efficient root colonization, are es...
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.
