Novel sex cells and evidence for sex pheromones in diatoms. [PDF]

PLoS ONE, 2011
BACKGROUND: Diatoms belong to the stramenopiles, one of the largest groups of eukaryotes, which are primarily characterized by a presence of an anterior flagellum with tubular mastigonemes and usually a second, smooth flagellum.

A New Insight Into Amicula, a Genus of Tiny Marine Benthic Diatoms With the Description of Two New Tropical Species and the Largest Mitogenome Known for a Stramenopile

Frontiers in Marine Science, 2022
The current article focuses on the morphological and molecular characterization of the often inconspicuous genus Amicula. This recently erected genus from brackish and marine sediments was monotypic but here we describe two new tropical species: Amicula ...

Mitochondrial Genome Reduction and Accelerated Evolution in Planktonic Foraminiferans

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
The mitochondrial genomes of the eukaryotic lineage Retaria (Foraminifera and Radiolaria) show reductions in multiple gene categories, including complex I, transfer RNAs (tRNAs), ribosomal proteins, and ribosomal RNAs. In planktonic foraminifera, this reduction is even more pronounced, with the potential loss of atp and other genes.

Diverse evolutionary trajectories for small RNA biogenesis genes in the oomycete genus Phytophthora

Frontiers in Plant Science, 2016
Gene regulation by small RNA pathways is ubiquitous among eukaryotes, but little is known about small RNA pathways in the Stramenopile kingdom.

Ecological Dynamics of Two Distinct Viruses Infecting Marine Eukaryotic Decomposer Thraustochytrids (Labyrinthulomycetes, Stramenopiles). [PDF]

PLoS ONE, 2015
Thraustochytrids are cosmopolitan osmotrophic or heterotrophic microorganisms that are considered as important decomposers in coastal ecosystems. However, because of a lack of estimation method for each genus or systematic group of them, relatively ...

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Deep‐sequencing shotgun metagenomics of Red Sea benthic sediments reveals biodiversity across the web of life, from viruses to animals. Despite the strong dominance of prokaryotic DNA, low‐abundance eukaryotic reads capture broad taxonomic diversity. Open‐ocean communities are primarily structured by depth, whereas coastal eukaryotic communities follow

Idetification of transcription factor genes and their correlation with the high diversity of Stramenopiles

, 2012
The biological diversity among Stramenopiles is striking; they range from large multicellular seaweeds to tiny unicellular species, they embrace many ecologically important algal (e.g., diatoms, brown algae), and heterotrophic (e.g., oomycetes) groups ...

Codon Adaptation of Plastid Genes.

PLoS ONE, 2016
Codon adaptation is codon usage bias that results from selective pressure to increase the translation efficiency of a gene. Codon adaptation has been studied across a wide range of genomes and some early analyses of plastids have shown evidence for codon

Reticulate evolution in eukaryotes: Origin and evolution of the nitrate assimilation pathway. [PDF]

PLoS Genetics, 2019
Genes and genomes can evolve through interchanging genetic material, this leading to reticular evolutionary patterns. However, the importance of reticulate evolution in eukaryotes, and in particular of horizontal gene transfer (HGT), remains ...
