Ten mutants of Anabaena PCC7120 were successfully constructed to express two genetic traits, ammonia production and the resistance to the Diuron herbicide, using transposon induced mutagenesis and UV-radiation. The ranges for heterocyst frequency and ammonia production of mutants were 4.2%-6.8% and 2.3-6.6 μmol mg dry wt h respectively. The herbicide-resistance threshold for all mutants was 2.0 mg L, above which the mutants started to decline in health as observed microscopically. The dry… CONTINUE READING
