Substrate-specific clades of active marine methylotrophs associated with a phytoplankton bloom in a temperate coastal environment [PDF]

open access: yes, 2008
Marine microorganisms that consume one-carbon (C1) compounds are poorly described, despite their impact on global climate via an influence on aquatic and atmospheric chemistry.

Microbial signatures in amniotic fluid at preterm birth and association with bronchopulmonary dysplasia

open access: yesRespiratory Research, 2023
Background Microbiome dysbiosis can have long-lasting effects on our health and induce the development of various diseases. Bronchopulmonary dysplasia (BPD) is a multifactorial disease with pre- and postnatal origins including intra-amniotic infection as

16S rRNA gene sequencing of mock microbial populations- impact of DNA extraction method, primer choice and sequencing platform [PDF]

open access: yes, 2016
peer-reviewedBackground Next-generation sequencing platforms have revolutionised our ability to investigate the microbiota composition of complex environments, frequently through 16S rRNA gene sequencing of the bacterial component of the

Mitochondrial 16S rRNA Sequence Diversity of Hominoids [PDF]

open access: yesJournal of Heredity, 2001
We determined nucleotide sequences of the 16S rRNA gene of mitochondrial DNA (mtDNA) (about 1.6 kb) for 35 chimpanzee, 13 bonobo, 10 gorilla, 16 orangutan, and 23 gibbon individuals. We compared those data with published sequences and estimated nucleotide diversity for each species. All the ape species showed higher diversity than human.

Information about variations in multiple copies of bacterial 16S rRNA genes may aid in species identification.

open access: yesPLoS ONE, 2019
Variable region analysis of 16S rRNA gene sequences is the most common tool in bacterial taxonomic studies. Although used for distinguishing bacterial species, its use remains limited due to the presence of variable copy numbers with sequence variation ...

16S rRNA Phylogeny of Sponge-Associated Cyanobacteria [PDF]

open access: yesApplied and Environmental Microbiology, 2005
ABSTRACT Phylogenetic analyses of 16S rRNA sequences of sponge-associated cyanobacteria showed them to be polyphyletic, implying that they derived from multiple independent symbiotic events. Most of the symbiont sequences were affiliated to a group of Synechococcus and Prochlorococcus

Genetic Diversity and Potential Function of Microbial Symbionts Associated with Newly Discovered Species of Osedax Polychaete Worms [PDF]

open access: yes, 2007
We investigated the genetic diversity of symbiotic bacteria associated with two newly discovered species of Osedax from Monterey Canyon, CA, at 1,017-m (Osedax Monterey Bay sp. 3 "rosy" [Osedax sp. MB3]) and 381-m (Osedax Monterey Bay sp.

Dumpster diving for diatom plastid 16S rRNA genes [PDF]

open access: yesPeerJ, 2021
High throughput sequencing is improving the efficiency of monitoring diatoms, which inhabit and support aquatic ecosystems across the globe. In this study, we explored the potential of a standard V4 515F-806RB primer pair in recovering diatom plastid 16S
