Novel motility mutants of synechocystis strain PCC 6803 generated by in vitro transposon mutagenesis

J Bacteriol. 2001 Oct;183(20):6140-3. doi: 10.1128/JB.183.20.6140-6143.2001.


We screened for transposon-generated mutants of Synechocystis sp. strain PCC 6803 that exhibited aberrant phototactic movement. Of the 300 mutants generated, about 50 have been partially characterized; several contained transposons in genes encoding chemotaxis-related proteins, while others mapped to novel genes. These novel genes and their possible roles in motility are discussed.
