The pangenome of (Antarctic) Pseudoalteromonas bacteria: evolutionary and functional insights
Pseudoalteromonas is a genus of ubiquitous marine bacteria used as model organisms to study the biological mechanisms involved in the adaptation to cold conditions. A remarkable feature shared by these bacteria is their ability to produce secondary metabolites with a strong antimicrobial and antitumor activity. Despite their biotechnological relevance,

Monospecific cover crops perpetuate soil biotic homogenization in croplands across diverse soils
Read the free Plain Language Summary for this article on the Journal blog. Abstract Croplands are known to support significant soil biotic homogenization. Cover crops are commonly used as a sustainable agriculture practice; however, many times these cover crops are composed of single‐species.

Heavy metals are common in Antarctic habitats. However, the adaptations of Antarctic microorganisms to heavy metals are poorly understood. One of the mechanisms of toxicity of transition metals is the formation of free radicals which damage the cell ...

RNA and DNA viruses can manipulate host cell death through various mechanisms. RNA viruses (H1N1, SARS‐CoV‐2) induce acute apoptosis, necroptosis, and pyroptosis to promote rapid viral transmission and epithelial barrier damage. In contrast, DNA viruses (HSV‐1, EBV) regulate these mechanisms to sustain a lytic‐latency cycle, evade immune response and ...

Characterisation of Hydrocarbon Degrading Antarctic Pseudomonas species [PDF]
Hydrocarbon contamination of Antarctica poses a threat to the unique and fragile ecosystems of this continent. Bioremediation, utilising indigenous hydrocarbon-degrading bacteria, has been proposed as an environmentally friendly method for clean up of ...

Aerobiology over Antarctica – a new initiative for atmospheric ecology [PDF]
The role of Aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales.

Unveiling microbial guilds and symbiotic relationships in Antarctic sponge microbiomes
Marine sponges host diverse microbial communities. Although we know many of its ecological patterns, a deeper understanding of the polar sponge holobiont is still needed.

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Mercury-resistant bacteria in Antarctic ecosystems
Aim. The research was focused on the assessment of the possible resistance of Antarctic microorganisms to mercury ions. Methods. Conventional microbiological methods of introducing of decimal dilutions to agar medium. Results. Microorganisms resistant to Hg2+ in high concentrations (up to 500 mg/l) were discovered among samples from Antarctica.
