PHYLOGENETIC RELATIONSHIPS BETWEEN IRANIAN ISOLATES OF MICROSPHAERA AND ERYSIPHE S. LAT. BASED ON rDNA INTERNAL TRANSCRIBED SPACERS SEQUENCES
To study the phylogenetic relationships between Erysiphe s. lat. and Microsphaera, the nucleotide sequences of internal transcribed spacers ofrDNA including 5.8S rDNA gene were determined for 23 taxa. The results showed that Erysiphe. section Erysiphe and Microsphaera are closely related and clustered together with strong bootstrap support (100%). All oftaxa belonging to this group produce coni...
متن کاملEvaluation of antifungal activity of Meliaceae family against Macrophomina phaseolina
Macrophomina phaseolina (Tassi) Goid is a soil-borne fungal pathogen that causes root rot disease in more than 500 plant species but no registered fungicide is available for its control. The present study was carried out to investigate the antifungal activity of aqueous leaf extracts of Azadirachta indica A. Juss., Melia azedarach L. and Toona ciliata Roxb. (Meliaceae) against M. phaseolina. Aq...
متن کاملBIOPESTICIDAL ACTIVITY OF Calotropis procera L. AGAINST Macrophomina phaseolina
BACKGROUND Mungbean [Vigna radiata (L.) Wilczek] is an important pulse crop globally. This imperative crop is severely affected by charcoal rot disease caused by Macrophomina phaseolina (Tassi) Goid. In the present study, the leaves of Calotropis procera L. were tested for their antifungal potential against M. phaseolina. MATERIALS AND METHODS Various concentrations i.e. 1%, 2.5%, 4%, 5.5% an...

متن کاملMolecular Identification of Six Steinernema Isolates and Characterization of their Internal Transcribed Spacers Regions
Molecular identification and genotyping of entomopathogenic nematodes (EPNs) are prerequisites for their proper classification, biodiversity studies, and their potential use in biological control programs. In Palestine, although several isolates of EPNs have been collected, phenotypically characterized, and assessed for their tolerance to cold and heat stresses, the molecular identification and...
