UROMYCES SPP. ON MEDICAGO AND TRIFOLIUM SPECIES IN IRAN
In the framework of study on rust fungi of Fabaceae and based on the study of herbarium and newly collected specimens, six Uromyces species are recognized on Medicago spp. and Trifolium spp. from Iran. Among these species, U. fallens is recorded as new member for the Iranian rust flora. U. striatus is recorded as main causal agent of rust on lucerne (Medicago sativa) in Iran. Moreover, U. trifo...
متن کاملAntibiotic susceptibility of Aspergillus Spp. isolated from contaminated food sources
Aspergillus niger and Aspergillus flavus are frequently reported fungal pathogens known to cause infections in food materials. Fungal growth on the food materials leads to nutritional loss and food spoilage. Consumption of these food materials can cause severe complications and diseases in humans. Antifungal agents are commonly administered to check fungal growth. Knowing the importance of food...
متن کاملPopulation genetic structure of Sinorhizobium meliloti and S. medicae isolated from nodules of Medicago spp. in Mexico.
We studied the genetic structure of 176 bacterial isolates from nodules of Medicago sativa, M. lupulina and M. polymorpha in fifteen sites distributed in three localities in Mexico. The strains were characterized by multilocus enzyme electrophoresis, plasmid profiles, PCR restriction fragment length polymorphism of 16S rRNA genes and of the intergenic spacer between 16S and 23S rRNA genes, and ...
متن کاملcharacterization of novel biosurfactant producing strains of bacillus spp. isolated from petroleum contaminated soil
background and objectives: biosurfactants are surface active agents with broad range commercial applications in various industries and have considerable advantages over their chemical counterparts. materials and methods: in this study, bacteria were isolated from contaminated and uncontaminated soil and selected during preliminary screening using hemolytic activity, oil spreading and oil collap...
متن کاملSpecificity in Legume-Rhizobia Symbioses
Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N₂) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia related to the taxonomy of the legumes from which they were isolated. The Leguminosae was divided into three sub-families, the Caesalpinioideae, ...
