Isolation and complementation of nitrogen fixation mutants of the cyanobacterium Anabaena sp. strain PCC 7120.

Journal of bacteriology - 1 Mar 1991

Buikema W J, Haselkorn R

Abstract excerpt

Approximately 140 mutants of Anabaena sp. strain PCC 7120 unable to grow aerobically on media lacking fixed nitrogen (Fix-) were isolated after mutagenesis with diethyl sulfate and penicillin enrichment. A large cosmid library of wild-type Anabaena sp. strain PCC 7120 DNA was constructed in a mini-RK-2 shuttle vector, and seven mutants representing several morphologically abnormal heterocyst phenotypes were...
