Expression of genes involved in phagocytosis in uncultured heterotrophic flagellates

Limnology and Oceanography, Volume 65, Issue S1, Page S149-S160, January 2020., 2020
Abstract Environmental molecular sequencing has revealed an abundance of microorganisms that were previously unknown, mainly because most had not been cultured in the laboratory. Within this novel diversity, there are the uncultured MAST clades (MArine STramenopiles), which are major components of marine heterotrophic flagellates (HFs) thought to be ...

Cyclotella alvarniensis (Stephanodiscaceae): ¿Diatomea moderna o fósil?

Anales del Jardín Botánico de Madrid, 2023
Cyclotella alvarniensis es considerada una especie fósil de diatomea del Mioceno Superior. La presencia de esta especie suele estar asociada a su proximidad a zonas de explotación de diatomita. Se han encontrado frústulas en algunas regiones de España (Murcia-Albacete), Francia, Suiza y recientemente en Senegal. Sin embargo, las causas de su dispersión

Coscinodiscophyceae and Fragilariophyceae (Diatomeae) in the Iguaçu River, Paraná, Brazil [PDF]

Acta Botanica Brasilica, 2014
A taxonomic survey was carried out on Coscinodiscophyceae and Fragilariophyceae found in the Iguaçu River catchment area within Iguaçu National Park, in the state of Paraná, Brazil. Between September 2007 and August 2008, we collected 24 samples from two stations on the Iguaçu River, upstream and downstream of the falls.

Environmental Factors, Not Biotic Competitive Interactions, Drive the Relative Abundance of Diatoms and Chlorophyta in the Coastal Areas of the Beibu Gulf: Evidence From 18S rDNA Metabarcoding and Partial Least Squares‐Path Modeling Analysis

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Using high‐throughput sequencing (HTS) analysis, a negative correlation was found between Bacillariophyta and Chlorophyta near the Dafeng River Estuary (DRE) and the Sanniang Bay (SNB) located in the Beibu Gulf, China. The partial least squares‐path modeling (PLS‐PM) analysis showed that both the differing responses of Chlorophyta and Bacillariophyta ...

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.
