Spatial Variability of Picoeukaryotic Communities in the Mariana Trench [PDF]

Scientific Reports, 2018
AbstractPicoeukaryotes play prominent roles in the biogeochemical cycles in marine ecosystems. However, their molecular diversity studies have been confined in marine surface waters or shallow coastal sediments. Here, we investigated the diversity and metabolic activity of picoeukaryotic communities at depths ranging from the surface to the ...

Marine Microbial Community Composition During the Upwelling Season in the Southern Benguela

Frontiers in Marine Science, 2020
The microbial communities of the southern Benguela upwelling region were sampled quarterly through 1 year, with sampling for prokaryotes taking place in May, September, November and February, spanning the 2015–2016 upwelling season. Picoeukaryote samples

Genomic transformation of the picoeukaryote Ostreococcus tauri. [PDF]

Journal of visualized experiments : JoVE, 2012
Common problems hindering rapid progress in Plant Sciences include cellular, tissue and whole organism complexity, and notably the high level of genomic redundancy affecting simple genetics in higher plants. The novel model organism Ostreococcus tauri is the smallest free-living eukaryote known to date, and possesses a greatly reduced genome size and ...

Fitness Effects of Spontaneous Mutations in Picoeukaryotic Marine Green Algae [PDF]

G3 Genes|Genomes|Genetics, 2016
AbstractEstimates of the fitness effects of spontaneous mutations are important for understanding the adaptive potential of species. Here, we present the results of mutation accumulation experiments over 265–512 sequential generations in four species of marine unicellular green algae, Ostreococcus tauri RCC4221, Ostreococcus mediterraneus RCC2590 ...

Photosynthetic Picoeukaryotes Diversity in the Underlying Ice Waters of the White Sea, Russia

Diversity, 2020
The White Sea is a unique basin combining features of temperate and arctic seas. The current state of its biocenoses can serve as a reference point in assessing the expected desalination of the ocean as a result of climate change.

Picoeukaryote-based biohybrid microrobots for active delivery in the kidney. [PDF]

Sci Adv
Confined spaces in the human body pose substantial challenges for biomedical procedures. Navigating these ultrasmall environments is essential for precise drug delivery, improving treatment outcomes and reducing adverse effects. Microrobots offer a promising approach to accessing these complex microenvironments.

Distribution and environmental correlations of picoeukaryotes in an Arctic fjord (Kongsfjorden, Svalbard) during the summer

Polar Research, 2019
Picoeukaryotes are numerous in the summer in the High-Arctic fjord Kongsfjorden, in western Spitsbergen, Svalbard. However, little research has been conducted on the community structure and diversity of picoeukaryotes.

Picoeukaryotes of the Micromonas genus: sentinels of a warming ocean [PDF]

The ISME Journal, 2018
Abstract Photosynthetic picoeukaryotesx in the genus Micromonas show among the widest latitudinal distributions on Earth, experiencing large thermal gradients from poles to tropics. Micromonas comprises at least four different species often found in sympatry.

Vertical distribution of picoeukaryotic diversity in the Sargasso Sea

Environmental Microbiology, 2007
Summary Eukaryotic molecular diversity within the picoplanktonic size‐fraction has primarily been studied in marine surface waters. Here, the vertical distribution of picoeukaryotic diversity was investigated in the Sargasso Sea from euphotic to abyssal waters, using size‐fractionated samples (< 2 μm). 18S rRNA
