molecular detection, genetic diversity and host specialization of iranian isolates of macrophomina phaseolina
macrophomina phaseolina is a soilborne pathogen with a worldwide distribution and a host range of over 500 plant species. to study the genetic diversity and host specialization of this fungus in iran, plants with signs and symptoms of charcoal rot were collected from 12 provinces during years 2006 to 2008. following isolation and purification, 52 isolates from 24 host plants were identified thr...
متن کاملMorphological and Pathogenic Variability among Macrophomina phaseolina Isolates Associated with Mungbean (Vigna radiata L.) Wilczek from Pakistan
Macrophomina phaseolina is a serious pathogen of many crops. In the present studies, 65 isolates of Macrophomina phaseolina from different agroecological regions of Punjab and Khyber Pakhtunkhwa provinces of Pakistan were analyzed for morphological and pathogenic variability. Regardless of their geographic origins, significant differences were detected among 65 isolates in their radial growth, ...
متن کاملEffect of crop rotation on specialization and genetic diversity of Macrophomina phaseolina
Charcoal rot, caused by Macrophomina phaseolina, is one of the most important diseases of soybean. Genetic variability among soybean isolates has been observed but the effect of host specialization on genetic variability has not been reported. In this work, isolates from soybean, corn and sunflower were evaluated based on cross inoculations and number of microsclerotia/g of roots. The highest a...
متن کاملVariation in Sensitivity Among Some Isolates of Macrophomina phaseolina Isolated from Cotton Roots to Flutolanil Fungicide
Toxicity of the fungicide Flutolanil was in vitro tested against 20 isolates of Macrophomina phaseolina and cotton seedlings of ten commercial cotton cultivars. The isolates were recovered from roots of cotton plants obtained from different cotton-growing areas in Egypt. Most of the tested isolates were sensitive to Flutolanil; however, they varied in sensitivity. Twenty-five percent of the iso...
متن کاملa study on genetic diversity of some isolates of macrophomina phaseolina using molecular marker; pcr-rflp and rapd
charcoal rot caused by macrophomina phaseolina is an injurious and economically important disease which causes heavy loss of yield to field and horticultural crops. thirty-three isolates of m. phaseolina were obtained from different host plants such as: soybean (glycine max.), melo (cucumis melo), bean (phaseolus vulgaris), pea (pisum sativum), pinus (pinus sp), blak-eyed susan (rudbeckia fulgi...
