Introducing mothur: Open-Source, Platform-Independent, Community-Supported Software for Describing and Comparing Microbial Communities
Patrick D. Schloss,Patrick D. Schloss,Sarah L. Westcott,Sarah L. Westcott,Thomas Ryabin,Justine R. Hall,Martin Hartmann,Emily B. Hollister,Ryan A. Lesniewski,Brian B. Oakley,Donovan H. Parks,Courtney J. Robinson,Jason W. Sahl,Blaz Stres,Gerhard G. Thallinger,David J. Van Horn,Carolyn F. Weber +16 more
TL;DR: M mothur is used as a case study to trim, screen, and align sequences; calculate distances; assign sequences to operational taxonomic units; and describe the α and β diversity of eight marine samples previously characterized by pyrosequencing of 16S rRNA gene fragments.
Journal ArticleDOI
The metatranscriptome of a deep-sea hydrothermal plume is dominated by water column methanotrophs and lithotrophs.
TL;DR: The biogeochemistry of Guaymas Basin hydroThermal plumes is mediated by microorganisms that are derived from seawater rather than from seafloor hydrothermal environments such as chimneys or sediments, and that hydrother mal inputs serve as important electron donors for primary production in the deep Gulf of California.
Journal ArticleDOI
Genome-enabled transcriptomics reveals archaeal populations that drive nitrification in a deep-sea hydrothermal plume
TL;DR: These unique data sets reveal populations of deep-sea AOA thriving in the ammonium-rich GB that are related to surface types, but with key genomic and physiological differences.
Journal ArticleDOI
Archaeal and bacterial diversity in an arsenic-rich shallow-sea hydrothermal system undergoing phase separation.
Roy E. Price,Ryan A. Lesniewski,Katja Sonja Nitzsche,Anke Meyerdierks,Chad W. Saltikov,Thomas Pichler,Jan P. Amend +6 more
TL;DR: Prokaryotic diversity in arsenic-rich shallow-sea vents off Milos Island is evaluated by comparative analysis of 16S rRNA clone sequences from two vent sites with similar pH and temperature but marked differences in salinity, suggesting arsenotrophy as an important metabolism in similar environments.
Journal ArticleDOI
Mineralogy Drives Bacterial Biogeography of Hydrothermally Inactive Seafloor Sulfide Deposits
Brandy M. Toner,Ryan A. Lesniewski,Jeffrey J. Marlow,Lindsey J. Briscoe,Cara M. Santelli,Wolfgang Bach,Beth N. Orcutt,Katrina J. Edwards +7 more
TL;DR: The relationship between mineralogy and microbial community composition in low-temperature, rock-hosted systems has not yet been resolved at any spatial scale, local or global as mentioned in this paper.
