HOMOLOGOUS STRAND EXCHANGE AND DNA HELICASE ACTIVITIES IN PLANT MITOCHONDRIA Daqing Song Department of Microbiology & Molecular Biology Master of Science Homologous recombination is critical for generating genetic variation in living organisms by exchange and rearrangement of DNA. Most of our knowledge about homologous recombination is limited to processes in bacteria or in eukaryotic nuclei. I...

Natural products play an important role in drug discovery and many approved therapeutics as well as drug candidates have been derived from natural sources. They have been the source of most of the active ingredients of medicines. The beneficial medicinal effects of plant materials typically result from the combinations of secondary products present in the plan. These secondary metabolites const...

The transmission of Escherichia coli O157:H7 from manure-contaminated soil and irrigation water to lettuce plants was demonstrated using laser scanning confocal microscopy, epifluorescence microscopy, and recovery of viable cells from the inner tissues of plants. E. coli O157:H7 migrated to internal locations in plant tissue and was thus protected from the action of sanitizing agents by virtue ...

The Nayband Formation was measured and sampled in Parvadeh area, southern Tabas city. In this area, this formation has a thickness of 1410 m, dividing into four members, namely Gelkan, Bidestan, Howz-e-sheikh and Howz-e-khan. A total 573 samples were treated for Palynological analysis, and only 120 samples were productive. A total of 57 miospore taxa and 11 plant macrofossil were encountered. B...
