Introduction: Production of a novel polygalacturonase (PG) active at pH = 3.0 and suitable to be used in fruit juice industries from Macrophomina phaseolina was evaluated. Suitable carbon, nitrogen and phosphorous forms were determined and the condition was optimized for higher PG production. Materials and methods: Macrophomina phaseolina was cultured in so called production medium. The secreto...

We report the first case of human infection with the fungal plant pathogen Macrophomina phaseolina in a Sri Lankan-born Canadian man following a renal transplant in India. The patient subsequently succumbed to invasive infection with Scytalidium dimidiatum. Molecular sequence analysis confirmed the identification of both fungi and revealed that they are related species within the ascomycete fam...

Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...

A microtiter plate-based enzyme immunoassay has been developed for phaseolinone, a phytotoxin isolated from the culture filtrate of the plant-pathogenic fungus Macrophomina phaseolina (Tassi) Goid. The smallest amount of phaseolinone detectable by the method is 5 pg per well. The method is validated by comparison with high-performance liquid chromatography and used to confirm and estimate phase...

Macrophomina phaseolina (Tassi) Goid is one of the most important soil-borne fungi that affects sesame and causes charcoal rot disease, with a great economic challenge to growers worldwide. Pathogenic molecular characterizations eleven M. isolates collected from different geographical regions in Egypt were carried out determine pathogenicity genetic diversity. Pathogenicity tests showed pathoge...

Rhizoctonia solani, Fusarium solani, F. oxysporum, and Macrophomina phaseolina were found to be associated with root rott and wilt symptoms of faba bean plants collected from different fieldes in New Valley governorate, Egypt. All the obtained isolates were able to attack faba bean plants (cv. Giza 40) causing damping-off and root rot/wilt diseases. R. solani isolates 2 and 5, F. solani isolate...
