Diel transcriptional response of a California Current plankton microbiome to light, low iron, and enduring viral infection. [PDF]

, 2019
Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Comparing the Environmental Influences and Community Assembly of Protist Communities in Two Anthropogenic Coastal Areas

Microorganisms
Anthropogenic stresses are intensively affecting the structure and function of microbial communities in coastal ecosystems. Despite being essential components of coastal ecosystems, the environmental influences and assembly processes of protist ...

Functional and phylogenetic analysis of the core transcriptome of Ochromonadales [PDF]

Metabarcoding and Metagenomics, 2017
Background Most protist lineages consist of members with diverging features e.g. different modes of nutrition and adaptations for life in different habitat types and climatic zones.

Seasonal changes in planktonic bacterivory rates under the ice-covered coastal Arctic Ocean [PDF]

, 2008
Bacterivory was determined in surface waters of Franklin Bay, western Arctic, over a seasonal ice-covered period (winter-spring, 2003-2004). The objectives were to obtain information on the functioning of the microbial food web under the ice, during ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Tumor Cell Migration May Be an Inherent “Foraging” Behavior

Medicine Advances, EarlyView.
Tumor cells gradually form pseudopodia, migrate to necrotic cells, make contact with them, and absorb necrotic cell debris. During this migration, small vesicles formed by dying tumor cells also gradually migrate toward living tumor cells. Once the nutrients from the necrotic cells have been completely absorbed, the living tumor cells will leave ...

Diagnostic test assessment on protist misconception

JPBI (Jurnal Pendidikan Biologi Indonesia), 2019
One of the fatal problems emerge in educational practice is misconception as it is related to the students’ understanding. Consequently, these must be detected at the beginning of learning process. This research was conducted to construct and develop the

Studies on Reticulitermes lucifugus Rossi (Isoptera: Rhinotermitidae): a review of associated hindgut flagellates and investigations on protist species of the Sicilian subspecies, R. lucifugus \u201cSicily\u201d [PDF]

, 2017
The present study was conducted on protist species from R. lucifugus \u201cSicily\u201d subspecies in a field site of Palermo (Sicily, Italy) on June 2015. Since protist species associated with R.

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.
