Comparing gene sequences of photosynthetic reaction center proteins and a key enzyme of bacteriochlorophyll biosynthesis from more than 150 genomes demonstrates the ancient roots of phototrophic bacteria. The presence and phylogeny of biosynthetic pathways of the compatible solutes ectoine and glycine betaine define groups of marine and halophilic phototrophic bacteria. The wide range of ecological niches conquered during evolution is demonstrated by the adaptation of cyanobacterial genera Scytonema, Tolypothrix, and Nostoc to different temperature ranges and the adaptation of Heliorestis species to alkaline habitats. Differences between phototrophic purple bacteria from marine and freshwater habitats are reflected in the preference for sulfidic and non-sulfidic niches. Also, a high proportion of siderophore producers was found among isolates from freshwater sources opposed to those from salty habitats . The primary colonization of carbonate rocks by a group of novel endolithic cyanobacteria and the following successions were studied over 9 months. The genomic characterization of the aerobic Dinoroseobacter strain AAP5, the strictly anaerobic and syntrophic Prosthecochloris ethylica, and the strictly anaerobic Heliorestis convoluta is reported. Significant differences in relation to oxygen are reflected in oxygen production by some species, oxygen tolerance over a wide range of concentrations, and the use of oxygen for energy generation or a strictly anaerobic lifestyle. Relations to oxygen are highlighted in papers on photooxidative stress, regulation of iron-sulfur cluster formation, and interactions of redox regulators. In situ metatranscriptomic and proteomic studies demonstrate the high metabolic flexibility of Chloroflexus aggregans in a hot spring microbial mat and show its adaptation to the changing conditions over day and night periods by a well-coordinated regulation of key metabolic processes for both phototrophic and chemotrophic growth. 606 $aResearch and information: general$2bicssc 610 $aadhesion protein 610 $aaerobic anoxygenic phototrophic bacteria 610 $aaerobic anoxygenic phototrophs 610 $aalkaliphilic bacteria 610 $aAlphaproteobacteria 610 $aanoxygenic phototroph 610 $aanoxygenic phototrophic bacteria 610 $aantisense promoters 610 $abacteriochlorophyll a 610 $abacteriochlorophyll biosynthesis 610 $abacteriochlorophyll g 610 $abioerosion 610 $abiological soil crust 610 $acarbon fixation 610 $aCAS assay 610 $aChpT 610 $aChromocurvus halotolerans strain EG19 610 $aCrp/Fnr 610 $aDnr 610 $adrylands 610 $ae-pili 610 $aectoine biosynthesis 610 $aenergy metabolism 610 $aeuendolith 610 $aevolution of anoxygenic photosynthesis 610 $afilamentous anoxygenic phototroph 610 $agene transfer agent 610 $agenomes of photosynthetic bacteria 610 $aglycine betaine biosynthesis 610 $agreen sulfur bacteria 610 $aheliobacteria 610 $aHeliorestis convoluta 610 $ahot springs 610 $airon-sulfur cluster 610 $aIrr 610 $aisc genes 610 $aIscR 610 $alarge multiheme cytochrome 610 $amassive blooms 610 $ametagenomic binning 610 $ametallophore 610 $ametatranscriptomics 610 $amicrobial mats 610 $amicrobiome 610 $amotility 610 $an/a 610 $aniche partitioning 610 $anitric oxide 610 $anitrogen fixing cyanobacteria 610 $aosmotic adaptation 610 $aOxyR 610 $aphotooxidative stress 610 $aphotosynthesis genes 610 $aphotosynthetic reaction center proteins 610 $aphotosynthetic symbionts 610 $aphototrophic purple bacteria 610 $aphylogenomics 610 $aphylogeny 610 $aphylogeny of osmolyte biosynthesis 610 $aproteomics 610 $apufM gene 610 $apurple nonsulfur bacteria 610 $aquorum sensing 610 $aRegA 610 $aRhodobacter capsulatus 610 $aRhodobacter sphaeroides 610 $aRhodobacteraceae 610 $arhodopsin 610 $aRhodovulum 610 $asiderophore 610 $asoda lake 610 $aSphingomonadaceae 610 $astress defense 610 $asuf genes 610 $asyntrophy 610 $atranscriptomics 615 7$aResearch and information: general 700 $aImhoff$b Johannes F$4edt$01302754 702 $aImhoff$b Johannes F$4oth 906 $aBOOK 912 $a9910557401903321 996 $aAdvances in the Biology of Phototrophic Bacteria$93026516 997 $aUNINA
