Journal ArticleDOI
Roseiflexus castenholzii gen. nov., sp. nov., a thermophilic, filamentous, photosynthetic bacterium that lacks chlorosomes.
TL;DR: A novel thermophilic, photosynthetic bacterium, designated strain HLO8T, was isolated from a bacterial mat in a Japanese hot spring and suggested that it belonged to the anoxygenic filamentous phototrophic bacteria represented by Chloroflexus aurantiacus, but was clearly distant from all members in this group.
Journal ArticleDOI
Horizontal transfer of genes coding for the photosynthetic reaction centers of purple bacteria
TL;DR: Phylogenetic trees were drawn and analyzed based on the nucleotide sequences of the 1.5-kb gene fragment coding for the L and M subunits of the photochemical reaction center of various purple photo-synthetic bacteria, which imply horizontal transfer of the genes that code for the photosynthetic apparatus in purple bacteria.
Journal ArticleDOI
Chloroflexus aggregans sp. nov., a Filamentous Phototrophic Bacterium Which Forms Dense Cell Aggregates by Active Gliding Movement
TL;DR: It is proposed that a new Chloroflexus species should be created for the new isolates of thermophilic filamentous photosynthetic bacteria isolated from bacterial mats in two separate hot springs in Japan, and the name of this new species is Chlor oflexus aggregans.
Journal ArticleDOI
Horizontal transfer of the photosynthesis gene cluster and operon rearrangement in purple bacteria.
Naoki Igarashi,Jiro Harada,Sakiko Nagashima,Katsumi Matsuura,Keizo Shimada,Kenji V. P. Nagashima +5 more
TL;DR: It was concluded that a horizontal transfer of the photosynthesis gene cluster from an ancestral species belonging to the α subclass to that of the β subclass of purple bacteria had occurred and was followed by rearrangements of the operons in this cluster.
Journal ArticleDOI
Quinones in chlorosomes of green sulfur bacteria and their role in the redox-dependent fluorescence studied in chlorosome-like bacteriochlorophyll c aggregates
TL;DR: It is suggested that quinones play a significant, but not exclusive role in controlling the fluorescence and in inhibiting energy transfer in chlorosomes under oxic conditions.
