Discovery of a kleptoplastic 'dinotom' dinoflagellate and the unique nuclear dynamics of converting kleptoplastids to permanent plastids
(Nature Research, 2019-07-19)
A monophyletic group of dinoflagellates, called ‘dinotoms’, are known to possess evolutionarily intermediate plastids derived from diatoms. The diatoms maintain their nuclei, mitochondria, and the ...
Diat.barcode, an open-access curated barcode library for diatoms
(Nature Research, 2019-10-22)
Diatoms (Bacillariophyta) are ubiquitous microalgae which produce a siliceous exoskeleton and which make a major contribution to the productivity of oceans and freshwaters. They display a huge diversity, ...
A rapid cleaning method for diatoms
(Taylor & Francis, 2019-07-18)
We describe here a protocol for cleaning diatoms when time is short and the amount of
sample is very limited. Essentially, the method consists of drying material onto coverslips and
cleaning it directly ...
Nitzschia fenestralis: A new diatom species abundant in the Holocene sediments of an eastern African crater lake
(Czech Phycological Society, 2020-02-18)
Nitzschia is common in the phytoplankton of several East African lakes. A new species, Nitzschia fenestralis, sp. nov. D. Grady, D.G. Mann et Trobajo was encountered at numerous depths in a 16 m sediment ...
DNA metabarcoding reveals differences in distribution patterns and ecological preferences among genetic variants within some key freshwater diatom species
(Elsevier, 2021-07-20)
Our study evaluates differences in the distribution and ecology of genetic variants within several ecologically important diatom species that are also key for Water Framework Directive monitoring of ...
Assessment of marine benthic diatom communities: insights from a combined morphological–metabarcoding approach in Mediterranean shallow coastal waters
(Elsevier, 2022-01-18)
We investigated the advantages and disadvantages of light microscope (LM)-based identifications and DNA metabarcoding, based on a 312-bp rbcL marker, for examining benthic diatom communities from ...
Phylotranscriptomics reveals the reticulate evolutionary history of a widespread diatom species complex
(Wiley, 2022-07-21)
In contrast to surveys based on a few genes that often provide limited taxonomic resolution, transcriptomes provide a wealth of genomic loci that can resolve relationships among taxonomically challenging ...
Ripe for reassessment: a synthesis of available molecular data for the speciose diatom family Bacillariaceae
(Elsevier, 2020-10-13)
The Bacillariaceae is a very species-rich family of raphid diatoms and includes the large and taxonomically difficult genus Nitzschia, whose species are often small-celled and finely structured and have ...
Metadata standards and practical guidelines for specimen and DNA curation when building barcode reference libraries for aquatic life
(Pensoft Publishers, 2021-02-26)
DNA barcoding and metabarcoding is increasingly used to effectively and precisely assess and monitor biodiversity in aquatic ecosystems. As these methods rely on data availability and quality of barcode ...
Evaluation and sensitivity analysis of diatom DNA metabarcoding for WFD bioassessment of Mediterranean rivers
(Elsevier, 2020-04-04)
Our study of 164 diatom samples from Catalonia (NE Spain) is the first to evaluate the applicability of DNA metabarcoding, based on high throughput sequencing (HTS) using a 312-bp rbcL marker, for ...
