Prevalence of classic, MLB-clade and VA-clade Astroviruses in Kenya and The Gambia [PDF]

open access: yesVirology Journal, 2015
La diarrea infecciosa conduce a una mortalidad significativa en los niños, con un 40 % de estas muertes ocurriendo en África. Los astrovirus humanos clásicos son una etiología bien establecida de la diarrea. En los últimos años, se han descubierto siete nuevos astrovirus (MLB1, MLB2, MLB3, VA1/HMO-C, VA2/HMO-B, VA3/HMO-A, VA4); sin embargo, ha habido ...

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Picocyanobacteria Community and Cyanophage Infection Responses to Nutrient Enrichment in a Mesocosms Experiment in Oligotrophic Waters

open access: yesFrontiers in Microbiology, 2020
Prochlorococcus and Synechococcus are pico-sized cyanobacteria that play a fundamental role in oceanic primary production, being particularly important in warm, nutrient-poor waters.

Genetic diversity in the env V1-V2 region of proviral quasispecies from long-term controller MHC-typed cynomolgus macaques infected with SHIVSF162P4cy [PDF]

open access: yes, 2018
Intra-host evolution of human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) has been shown by viral RNA analysis in subjects who naturally suppress plasma viremia to low levels, known as controllers.

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Primate phylogeny: molecular evidence for a pongid clade excluding humans and a prosimian clade containing tarsiers [PDF]

open access: yes, 2009
Interpretations of molecular data by the modern evolution theory are often sharply inconsistent with paleontological results. This is to be expected since the theory is only true for microevolution and yet fossil records are mostly about macroevolution.

Molecular, morphological, and phytochemical evidence for a broad species concept of Plagiochila bifaria (Hepaticae) [PDF]

open access: yes, 2004
Debate over the synonymy of the European Plagiochila killarniensis and the Neotropical P bifaria of R sect. Arrectae has focused on differences in secondary metabolite composition.

A revision of the Solanum elaeagnifolium clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae) [PDF]

open access: yesPhytoKeys, 2017
Le clade Solanum elaeagnifolium (clade Elaeagnifolium) contient cinq espèces de petits arbustes, souvent rhizomateux, provenant des déserts et des forêts sèches d'Amérique du Nord et du Sud. Les membres du clade étaient auparavant classés dans les sections Leprophora, Nycterium et Lathyrocarpum, et on ne pensait pas qu'ils étaient étroitement liés.

Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium

open access: yesFEBS Open Bio, EarlyView.
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Use of Whole Genome Phylogeny and Comparisons in the Development of a Multiplex-PCR Assay to Identify Sequence Type 36 Vibrio parahaemolyticus [PDF]

open access: yes, 2015
Vibrio parahaemolyticus sequence type (ST) 36 strains that are native to the Pacific Ocean have recently caused multi-state outbreaks of gastroenteritis linked to shellfish harvested from the Atlantic Ocean.
