Structure of the 16 S ribosomal RNA of the thermophilic cyanobacterium Chlorogloeopsis HTF ('Mastigocladus laminosus HTF') strain PCC7518, and phylogenetic analysis.

The thermophilic cyanobacterial strain, PCC7518, originally identified as 'Mastigocladus laminosus HTF' does not show branchings or heterocysts. The absence of branchings supports the later assignment to the genus Chlorogloeopsis. The absence of heterocysts may be the result of a mutation because heterocysts were observed in the original isolate… (More)
