Molecular Characterization of Rhizoctonia Solani Ag-7 Causing Root Rot on Cotton Crop in India
Rhizoctonia solani (Kuhn) is one of the most important cotton crop pathogens. Rhizoctonia solani anastomosis groups (AGs) 7 and 4 are proven to be the most common pathogenic fungal strains on cotton crop. AG-7 can cause root rot in plants while damping-off of seedlings is most frequently attributed to AG-4. Sequencing of the ITS (Internal Transcribed Spacer) region of ribosomal DNA was performe...
متن کاملGenetic structure of populations of Rhizoctonia solani AG-3 on potato in eastern North Carolina.
A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was developed to identify and differentiate genotypes of Rhizoctonia solani anastomosis group 3 subgroup PT (AG-3 PT), a fungal pathogen of potato. Polymorphic co-dominant single-locus PCR-RFLP markers were identified after sequencing of clones from a genomic library and digestion with restriction enzymes. Mu...
متن کاملStem Rot on Adzuki Bean (Vigna angularis) Caused by Rhizoctonia solani AG 4 HGI in China
During late August and early September 2011, stem rot symptoms were observed on adzuki bean plants (Vigna angularis) growing in fields located in Beijing and Hebei Province, China, respectively. In this study, four isolates were obtained from infected stems of adzuki bean plants. Based on their morphology, and sequence and polymerase chain reaction-restriction fragment length polymorphism (PCR-...
متن کاملبررسی چند شکلی DNA در جمعیت‌های AG-4 Rhizoctonia solani با استفاده از نشانگر مولکولی rDNA RFLP
توالیهای DNA ریبوزومی بهدلیل اینکه دارای کپیهای زیادی از ژنهای rRNA و نیز درجه بالایی از تغییر میباشند، بهمنظور بررسی روابط فیلوژنی در محدوده وسیعی از سطوح تاکسونومی مورد استفاده قرار میگیرند. نواحی ITS و فواصل داخل ژنی DNA ریبوزومی هستهای، واحدهای تکراری تکامل یافته ثابت میباشند و ممکن است در بین گونه های داخل یک جنس یا در بین افراد یک جمعیت متغیر باشند. بهمنظور ارزیابی چند شکلی نوا...
متن کاملDistinctively variable sequence-based nuclear DNA markers for multilocus phylogeography of the soybean- and rice-infecting fungal pathogen Rhizoctonia solani AG-1 IA
A series of multilocus sequence-based nuclear DNA markers was developed to infer the phylogeographical history of the Basidiomycetous fungal pathogen Rhizoctonia solani AG-1 IA infecting rice and soybean worldwide. The strategy was based on sequencing of cloned genomic DNA fragments (previously used as RFLP probes) and subsequent screening of fungal isolates to detect single nucleotide polymorp...
