Screening Brazilian Macrophomina phaseolina isolates for alkaline lipases and other extracellular hydrolases.
Macrophomina phaseolina, phylum Ascomycota, is a phytopathogenic fungus distributed worldwide in hot dry areas. There are few studies on its secreted lipases and none on its colony radial growth rate, an indicator of fungal ability to use nutrients for growth, on media other than potato-dextrose agar. In this study, 13 M. phaseolina isolates collected in different Brazilian regions were screene...
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 کاملProduction of Macrophomina phaseolina Conidia by Multiple Soybean Isolates in Culture
Macrophomina phaseolina (Tassi) Goid., a pycnidia-producing fungus, is one of the most important soilborne pathogens, infecting over 500 plant species in more than 100 plant families around the world (1,18). It causes a major disease of soybean (Glycine max (L.) Merr.) called charcoal rot (18). Symptoms on soybean include blight of emerging seedlings, wilting, early maturation, and incomplete p...
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...
متن کاملGenetic diversity and differentiation of Indian isolates of Phytophthora infestans as revealed by RAPD analysis.
Sixty-seven isolates of Phytophthora infestans collected from Himalayan hill regions and subtropical planes of India were characterized by RAPD markers to assess diversity and differentiation based on location of origin. Ten random decamer primers generated 161 polymorphic fragments. Association of P. infestans isolates on the dendrogram and PCO plot revealed two clear grouping based on geograp...
