The dynamic spore [PDF]

Proceedings of the National Academy of Sciences, 2003
Most bacteria can, at least to some degree, hunker down during periods of stress and wait for good times to return. No cells, however, do this as effectively as those Bacilli and Clostridia that form spores. Dormant cells produced by these bacteria can survive most environmental challenges found on earth and even a few in outer space and can remain ...

Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

Advanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

A Third Way for Entomophthoralean Fungi to Survive the Winter: Slow Disease Transmission between Individuals of the Hibernating Host

Insects, 2013
In temperate regions, insect pathogenic fungi face the challenge of surviving through the winter. Winter is a time when hosts are immobile, low in number or are present in a stage which is not susceptible to infection. Fungi from Entomophthoromycota have

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

Advanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose

Anthrax Toxins in Context of Bacillus anthracis Spores and Spore Germination

Toxins, 2015
The interaction of anthrax toxin or toxin components with B. anthracis spores has been demonstrated. Germinating spores can produce significant amounts of toxin components very soon after the initiation of germination.

CAUIM: Amazonian Cassava‐Based Programmable Biocolloid

Advanced Intelligent Systems, EarlyView.
Bridging indigenous heritage and computation, this work introduces the usage of cauim, a traditional Amazonian cassava fermented beverage, as a programmable memristive‐like substrate and resistance switching. The material exhibits frequency‐dependent dynamics enabling reconfigurable Boolean logic operations.

Aging and longevity in decades‐old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays

American Journal of Botany, EarlyView.
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Morphological and taxonomical studies in Blechnum (Blechnaceae-Pteridophyta): B. tabulare and B. magellanicum

Anales del Jardín Botánico de Madrid, 2008
Specimens of B. tabulare and B. magellanicum from their whole geographical area were studied, and taxa were treated as different species. The following characters were analyzed: rhizomes, rhizomatic scales, stipes, division of dimorphic laminae, outline,
