Leuconostoc spp. Associated with Root Rot in Sugar Beet and Their Interaction with Rhizoctonia solani.
Rhizoctonia root and crown rot is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc spp. Initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood; therefore, a more thorough investigation was conducted. In total, 203 Leuconostoc isolates were ...
متن کاملMorphological and molecular characterization of Oomycetes associated with root and crown rot of cucurbits in Kermanshah province, Iran
Pythium and Phytophthora are among the most well-known plant pathogens around the world that cause rotting of seeds, root, and crown, seedling death, and soft rot of fruits in contact with the soil. In this research, 347 isolates of these two genera and their close genus, Phytopythium were isolated from the cucurbits fields in Kermanshah province, Iran and examined in...
متن کاملMolecular 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 کاملEthyl Methane Sulphonate Induced Desynaptic Variants in Ajwain (Trachyspermum ammi (L.) Sprague)
Synaptic mutants are the subject of a special concern to cytologists and geneticists as they hold the variability in their recombination pattern. Seeds of Trachyspermum ammi (L.) Sprague (ajwain) were treated with Ethyl Methane Sulphonate (EMS) solution at 3 different concentrations viz. 0.1%, 0.3% and 0.5% for 5 h, prepared in potassium phosphate buffer with 7.0 pH. During meiotic observation ...
متن کاملpathogenic variability and genetic diversity of fusarium solani isolates and its association with sugarbeet root rot
diseased samples with root rot symptoms were collected from different sugar beet growing areas. from rotted roots, 20 fungal isolates were identified as fusarium solani based on morphological characteristics .pathogenecity of the isolates was studied in in vitro condition on sugar beet roots. the results showed pathogenic variability among the isolates. cluster analysis divided the isolates int...
