Aqueous leaf extract of four different species of Datura viz. D.stramonium L., D. innoxia Mill.Gard, D. metal L. and D. ferox L. Amoen were tested for their antifungal activity against phytopathogenic molds in terms of mycelial growth of Alternaria solani and Fusarium oxysporum f.sp. udum causing early blight of tomato and wilt of pigeonpea respectively. The extract of Datura sp. at 5, 10, 15 a...

1-Hydroxyphenazine (1-OH-PHZ), a natural product from Pseudomonas aeruginosa strain SD12, was earlier reported to have potent antifungal activity against Rhizoctonia solani. In the present work, the antifungal activity of 1-OH-PHZ on 40S ribosomal S9 protein was validated by molecular docking approach. 1-OH-PHZ showed interaction with two polar contacts with residues, Arg69 and Phe19, which inh...

Bu çalışmada, nane yetiştiriciliğinde önemli hastalıklara sebep olan fungal patojenlerden Fusarium oxysporum ve Rhizoctonia solani' ye karşı Trichoderma harzianum virens biyolojik kontrol etmenlerinin etkisi araştırılmıştır. aşamada solgunluk belirtisi gösteren bitkilerinin köklerinden yapılan izolasyonlar sonucunda F. R. solani izolatları elde edilmiş tanıları yapılmıştır. In vivo’da T. biyoet...

Eleven antifungal drugs were tested against representative isolates of the four phylogenetic clades of the Fusarium solani species complex obtained in a multilocus sequence analysis. They all showed very poor activity, with no differences among the clades. Amphotericin B was the most active drug.

The antifungal activity of 40 coumarins was tested against the fungal strains: Candida albicans (ATCC 14053), Aspergillus fumigatus (ATCC 16913) and Fusarium solani (ATCC 36031), using the broth microdilution method. Osthenol showed the most effective antifungal activity among all the compounds tested, with a MIC value of 125 microg/ml for Fusarium solani and 250 micro/ml for Candida albicans a...

Expression of the linear DNA plasmid-encoded protein (RS224) from the plant-pathogenic fungus Rhizoctonia solani isolate H-16, anastomosis group 2-2, and its localization were studied. Extracts from Escherichia coli cells expressing the open reading frame (ORF) of RS224 (RS224ORF in pRS224) contain a 92-kDa T7.Tag-RS224orf fusion protein. Antisera raised against the fusion protein obtained from...

A study was undertaken to explore the effect of volatile oils from Eucalyptus citriodora and its major constituent citronellal against two well-known rice pathogens, Rhizoctonia solani and Helminthosporium oryzae. The radial growth and dry weight of both the test fungi were drastically reduced in response to the volatile oils. A complete inhibition of R. solani and H. oryzae was observed at 10 ...

Bioassay-guided separation with an eye toward antifungal activity led to the isolation of the new alkaloid 5-(1̀,1̀-dimethylallyl)-8-hydroxyfuro[2-3-b] quinoline (1) and the known biscoumarin daphnoretin (2) as the active constituents of the chloroform extract obtained from the leaves of Ruta chalepensis. The structures of the metabolites were elucidated on the basis of their spectral characteris...
