Biosynthesis of 2-methylbacteriohopanepolyols by an anoxygenic phototroph.
Sedimentary 2-methyhopanes have been used as biomarker proxies for cyanobacteria, the only known bacterial clade capable of oxygenic photosynthesis and the only group of organisms found thus far to produce abundant 2-methylbacteriohopanepolyols (2-MeBHPs). Here, we report the identification of significant quantities of 2-MeBHP in two strains of the anoxygenic phototroph Rhodopseudomonas palustr...
متن کاملGenome Sequences and Photosynthesis Gene Cluster Composition of a Freshwater Aerobic Anoxygenic Phototroph, Sandarakinorhabdus sp. Strain AAP62, Isolated from the Shahu Lake in Ningxia, China
We report the first genome sequence from the recently established alpha-4 proteobacterial genus Sandarakinorhabdus. The genome of the Sandarakinorhabdus sp. strain AAP62 contains a photosynthesis gene cluster carrying major genes for bacterial reaction centers. The presence of genes related to aerobic respiratory electron transport confirms the lifestyle of this organism as an aerobic anoxygeni...
متن کاملWhole-Genome Sequences of an Aerobic Anoxygenic Phototroph, Blastomonas sp. Strain AAP53, Isolated from a Freshwater Desert Lake in Inner Mongolia, China
Blastomonas is a strictly aerobic bacteriochlorophyll a-producing genus within the alpha-4 Proteobacteria. Here we report the first genome sequence from this genus. The draft genome of Blastomonas sp. strain AAP53 contains a split photosynthesis gene cluster and two gene clusters encoding a flagellar system. Genes for the autotrophic CO2 fixation pathway are absent.
متن کاملGenetic Diversity and Molecular Phylogeny of Iranian Sheep Based on Cytochrome b Gene Sequences
Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...
متن کاملMolecular phylogenetics before sequences
From 1971 to 1985, Carl Woese and colleagues generated oligonucleotide catalogs of 16S/18S rRNAs from more than 400 organisms. Using these incomplete and imperfect data, Carl and his colleagues developed unprecedented insights into the structure, function, and evolution of the large RNA components of the translational apparatus. They recognized a third domain of life, revealed the phylogenetic ...
