Surviving global change: a review of the impacts of drought and dewatering on freshwater mussels

open access: yesBiological Reviews, Volume 100, Issue 1, Page 275-307, February 2025.
ABSTRACT The increase in the frequency and intensity of droughts and heatwaves caused by climate change poses a major threat to biodiversity. In aquatic systems, sedentary species such as freshwater mussels are generally considered more vulnerable to changes in habitat conditions than mobile species such as fish.

Incorporation in vitro of labeled amino acids into proteins of rabbit reticuloytes [PDF]

open access: yes, 1952
Continuing our work on the incorporation of labeled amino acids into proteins (1), we have begun a study of the incorporation in vitro of C14-labeled glycine, L-histidine, L-leucine, and L-lysine into the proteins of rabbit reticulocytes.

Photosynthetic H2 production: Lessons from the regulation of electron transfer in microalgae

open access: yesGCB Bioenergy
Green hydrogen, produced during microalgal photosynthesis, is regarded as one of the most promising sustainable energy sources. It utilizes sunlight and water, which are essentially unlimited, and its combustion results in only water as a waste product ...

Differential expression of two types of sucrose synthase-encoding genes in wheat in response to anaerobiosis, cold shock and light [PDF]

open access: yes, 1990
The expression of two types of sucrose synthase-encoding genes, Ss1 and Ss2, in hexaploid wheat (Triticum aestivum, L.), has been investigated using type-specific probes, corresponding to the 250–270 bp C-terminal portions of the respective cDNA clones ...

Acute-Stress Biomarkers in Three Octopodidae Species After Bottom Trawling [PDF]

open access: yes, 2019
Several Octopodidae species have a great potential for the diversification of worldwide aquaculture. Unfortunately, the lack of stress-related biomarkers in this taxon results an obstacle for its maintenance in conditions where animal welfare is of ...

ArxA From Azoarcus sp. CIB, an Anaerobic Arsenite Oxidase From an Obligate Heterotrophic and Mesophilic Bacterium

open access: yesFrontiers in Microbiology, 2019
Arsenic is a toxic element widely distributed in nature, but numerous bacteria are able to resist its toxicity mainly through the ars genes encoding an arsenate reductase and an arsenite efflux pump.
