Abstract excerpt

Mutants having partially repressed glutamine sythetase (transferase) activity and high nitrogenase activity were isolated following transposon mutagenesis. Two of these mutants M11 and M73 showed a decrease in heterocyst frequency compared with the wild type strain. The level of the enzyme nitrog...
