Findings from University of Queensland Provides New Data about Cyanobacteria (An Expanded Genomic Representation of the Phylum Cyanobacteria)

Life Science Weekly |


By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Cyanobacteria. According to news reporting originating from St. Lucia, Australia, by NewsRx correspondents, research stated, "Molecular surveys of aphotic habitats have indicated the presence of major uncultured lineages phylogenetically classified as members of the Cyanobacteria. One of these lineages has recently been proposed as a nonphotosynthetic sister phylum to the Cyanobacteria, the Melainabacteria, based on recovery of population genomes from human gut and groundwater samples." Our news editors obtained a quote from the research from the University of Queensland, "Here, we expand the phylogenomic representation of the Melainabacteria through sequencing of six diverse population genomes from gut and bioreactor samples supporting the inference that this lineage is nonphotosynthetic, but not the assertion that they are strictly fermentative. We propose that the Melainabacteria is a class within the phylogenetically defined Cyanobacteria based on robust monophyly and shared ancestral traits with photosynthetic representatives." According to the news editors, the research concluded: "Our findings are consistent with theories that photosynthesis occurred late in the Cyanobacteria and involved extensive lateral gene transfer and extends the recognized functionality of members of this phylum."
