Effect Of Some Chemicals On Certain Genetical Characters In Streptomyces scabies

Study the mutagenic effects of diethylamine, nitrous acid and acriflavine an a highly pathogenic isolate of streptomyees scabies and to spend some attemts to develop a parasexual Cycle for this organism . The importance of these studies can be deduced from the fact that any new host variety which preved to be resistant to a particular pathogen might llose this character by the developing of new strains through mutations, hetenocaryens, dipoloidization and recombinations.
