From isolation to insights: mitochondrial complex I in the diatom Phaeodactylum tricornutum

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Diatoms are among the most ecologically successful microalgae, contributing significantly to marine primary production and global carbon cycling. Their distinctive metabolic architecture, shaped by a complex evolutionary history involving secondary endosymbiosis, includes a highly compartmentalized cell organization and unique metabolic ...

Structure of a Protozoan Virus from the Human Genitourinary Parasite Trichomonas vaginalis [PDF]

open access: yes, 2013
The flagellated protozoan Trichomonas vaginalis is an obligate human genitourinary parasite and the most frequent cause of sexually transmitted disease worldwide. Most clinical isolates of T.

Giardia duodenalis Infections in Humans and Other Animals in China

open access: yesFrontiers in Microbiology, 2017
Giardia duodenalis is an important zoonotic pathogen in both public and veterinary health, and has been genotyped into at least eight assemblages (A–H), each with a distinct host range.

Comparing Sediment and Water eDNA Metabarcoding for Monitoring Aquatic Biodiversity in a Plateau Lake

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Using multi‐locus eDNA metabarcoding of sediment and water samples collected from a plateau lake, this study systematically compared taxonomic diversity and community composition between the two sample types across the tree of life from archaea to mammals.

Nanopore sequencing significantly improves genome assembly of the eukaryotic protozoan parasite Trypanosoma cruzi [PDF]

open access: yes, 2018
Chagas disease was described by Carlos Chagas, who first identified the parasite Trypanosoma cruzi from a two-year-old girl called Berenice. Many T. cruzi sequencing projects based on short reads have demonstrated that genome assembly and downstream comparative analyses are extremely challenging in this species, given that half of its genome is ...

On the extent and role of the small proteome in the parasitic eukaryote Trypanosoma brucei [PDF]

open access: yes, 2014
Background: Although technical advances in genomics and proteomics research have yielded a better understanding of the coding capacity of a genome, one major challenge remaining is the identification of all expressed proteins, especially those less than ...

Negative Regulators of an RNAi-Heterochromatin Positive Feedback Loop Safeguard Somatic Genome Integrity in Tetrahymena

open access: yesCell Reports, 2017
RNAi-mediated positive feedback loops are pivotal for the maintenance of heterochromatin, but how they are downregulated at heterochromatin-euchromatin borders is not well understood.

Programming the Infant Gut: How Maternal and Early Life Nutrition Shape the Infant Microbiome and Long‐term Health—A Narrative Review

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 2, 29 January 2026.
Good nutrition in pregnancy and early life plays a key role in shaping the offspring gut microbiota, which supports healthy growth, immune maturation, and neurodevelopment. Poor maternal and early‐life diets can disrupt this process, increasing the risk of obesity, undernutrition, and disease later in life.

Mapping the Germ-Line and Somatic Genomes of a Ciliated Protozoan,Tetrahymena thermophila [PDF]

open access: yesGenome Research, 1998
Ciliates are among the very few eukaryotes in which the powers of molecular biology, conventional genetics, and microbial methodology can be synergistically combined. Because ciliates also are distant relatives of vertebrates, fungi, and plants, the sequencing of a ciliate genome will be of import to our understanding of eukaryotic biology. Tetrahymena

The ever unfolding story of cAMP signaling in trypanosomatids: vive la difference! [PDF]

open access: yes, 2015
Kinetoplastids are unicellular, eukaryotic, flagellated protozoans containing the eponymous kinetoplast. Within this order, the family of trypanosomatids are responsible for some of the most serious human diseases, including Chagas disease (Trypanosoma ...
