Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard

Identification and Characterization of Fusarium Species Causing Watermelon Fruit Rot in Northern Thailand

Plants, 2023
Fruit rot caused by phytopathogenic fungi is one of the major diseases affecting watermelons (Citrullus lanatus) around the world, which can result in unmarketable fruits and significant economic losses.

Microbial Diversity of Marine Sponges [PDF]

, 2003
The recent application of molecular microbial ecology tools to sponge-microbe associations has revealed a glimpse into the biodiversity of these microbial communities, that is considered just 'the tip of the iceberg'. This chapter provides an overview over these new findings with regard to identity, diversity and distribution patterns of sponge ...

Giving microbial diversity a home [PDF]

Nature Reviews Microbiology, 2009
Efforts to house environmental microbial culture collections, resources and data are lagging behind the speed of discovery in the scientific community. Emerson and Wilson explain the need to increase the investment in biological resource centres to meet this growing challenge.

Microbial Diversity: A Bonanza of Phyla [PDF]

Current Biology, 2015
Metagenomics and single-cell genomics are now the gold standard for exploring microbial diversity. A new study focusing on enigmatic ultra-small archaea greatly expands known genetic diversity within Archaea, and reports the first complete archaeal genomes reconstructed from metagenomic data only.

Presence of a loner strain maintains cooperation and diversity in well-mixed bacterial communities [PDF]

, 2016
Cooperation and diversity abound in nature despite cooperators risking exploitation from defectors and superior competitors displacing weaker ones. Understanding the persistence of cooperation and diversity is therefore a major problem for evolutionary ...

Microbial Diversity and Biosignatures: An Icy Moons Perspective [PDF]

Space Science Reviews, 2020
The icy moons of the outer Solar System harbor potentially habitable environments for life, however, compared to the terrestrial biosphere, these environments are characterized by extremes in temperature, pressure, pH, and other physico-chemical conditions.

Cleavage of Bcl-2-associated athanogene by metacaspase determines plant antiviral immunity

Nature Communications
Nucleotide-binding leucine-rich repeat receptors (NLRs) function as core components of innate immunity in both plants and animals. In animals, NLR activation initiates caspase-mediated immune signaling.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Insertion sequences accelerate genomic convergence of multidrug resistance and hypervirulence in Klebsiella pneumoniae via capsular phase variation

Genome Medicine
Background The convergence of resistance and hypervirulence in Klebsiella pneumoniae represents a significant public health threat, driven by the horizontal transfer of plasmids. Understanding factors affecting plasmid transfer efficiency is essential to
