The in vitro effect of water activity (0.995, 0.98, 0.95, 0.90 and 0.85) and temperature (25 and 15 degrees C) on competing abilities of the biocontrol agent Penicillium oxalicum against Fusarium oxysporum fsp. lycopersici, a tomato pathogen, and Fusarium oxysporum fsp. gladioli, a gladiolus pathogen, was evaluated. The aim of this study was to assess the suitability of P. oxalicum to be applie...

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...

There has been commendable development in the field of biosynthesis of nanoparticles due to their low cost, environment friendly approach. One such biological entity employed in the synthesis is a fungus, Fusarium oxysporum that has shown hopes for a sustainable synthesis of many nanoparticles. In this review we will give an overview of the synthesis of nanoparticles using green methods and the...

The vascular wilt of tomato caused by Fusarium oxysporum f.sp. lycopersici is an important soil borne pathogen causes severe yield loss. The molecular characterization and their interaction with its host is necessary to develop a protection strategy. 20 isolates of F. oxysporum f.sp. lycopersici (FOL) were isolated from wilt infected tomato plants across Tamil Nadu. They were subjected to cultu...
