Inter-annual depth-dependent toxicity and bioaccumulation of cadmium in marine benthic protist communities

Oceanologia, 2007
The toxicity and bioaccumulation of cadmium in a marine benthic protist community were examined at different depths within the sediment. For this purpose, sediment-water microcosms with 1000 µg Cd dm-3 of the pollutant were used in two assays.

Some mixotrophic flagellate species selectively graze on Archaea [PDF]

, 2016
Altres ajuts: Spanish Ministry of the Environment project EGALA (OAPN-124/2010)Many phototrophic flagellates ingest prokaryotes. This mixotrophic trait becomes a critical aspect of the microbial loop in planktonic food webs because of the typical high ...

Soil protists

FEMS Microbiology Reviews, 2018
Protists include all eukaryotes except plants, fungi and animals. They are an essential, yet often forgotten, component of the soil microbiome. Method developments have now furthered our understanding of the real taxonomic and functional diversity of soil protists.

Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

The FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.

Summertime plankton ecology in Fram Strait - a compilation of long- and short-term observations [PDF]

, 2015
Between Greenland and Spitsbergen, Fram Strait is a region where cold ice-covered Polar Water exits the Arctic Ocean with the East Greenland Current (EGC) and warm Atlantic Water enters the Arctic Ocean with the West Spitsbergen Current (WSC).

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Screening for the ciliate Buxtonella sulcata in free-ranging dairy cattle on Terceira Island, Azores archipelago

Parasite
Buxtonella sulcata is an alveolate ciliate protist, historically considered a commensal of the gastrointestinal tract of cattle. Despite the fact that its cysts are morphologically identical to those of Balantioides coli, molecular identification ...

Gaining extensive resistance against clubroot disease through the disruption of a susceptibility gene

Journal of Integrative Plant Biology, EarlyView.
This Commentary examines research by Wu et al. showing that β‐1,3‐glucan synthase‐like 5 (GSL5) functions as a key gene for susceptibility to clubroot in Brassica family members by suppressing immunity regulated by jasmonic acid. Inaction of GSL5 through genome editing provides broad‐spectrum resistance to clubroot.

Diversity and seasonal dynamics of the marine diatom family Chaetocerotaceae (Bacillariophyta, Mediophyceae) in Catalan coastal waters (northwest Mediterranean)

Journal of Phycology, EarlyView.
Abstract The family Chaetocerotaceae includes the genera Chaetoceros and Bacteriastrum, with Chaetoceros being one of the most cosmopolitan, abundant, and diverse diatom genera in the oceans. This study investigated the diversity and seasonal dynamics of the Chaetocerotaceae in surface waters of two coastal sites along the Catalan coast (Barcelona and ...
