Evaluation and comparison of alpha- and beta-amanitin toxicity on MCF-7 cell line [PDF]

, 2014
Background/aim: Alpha- and beta-amanitins are the main toxins of the poisonous Amanita phalloides mushroom. Although there are many studies available concerning alpha-amanitin, there are limited data about beta-amanitin in the literature. Therefore, this

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, Volume 13, Issue 36, 29 June 2026.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Predator–Microbe Dynamics Inform Strategies for Robust Synthetic Community Assembly

Environmental Microbiology, Volume 28, Issue 6, June 2026.
This Review introduces ecological principles of predator–prey interactions as a new dimension in SynCom design. By linking microbial defence traits, encounter dynamics, and adaptive buffering, it outlines a framework for constructing predator‐resistant synthetic communities with enhanced resilience, stability, and functional performance under natural ...

Über die Inhaltsstoffe des grünen Knollenblätterpilzes, XLIV Die Konfiguration der hydroxylierten Isoleucine der Amatoxine [PDF]

, 1974
Durch Röntgenstrukturanalyse seines γ-Lacton-hydrobromids wurde die absolute Konfiguration jenes γ-Hydroxyisoleucins, das im γ-Amanitin vorkommt, als (2S,3R,4S)-2-Amino-3-methyl-4-hydroxyvaleriansäure (6) bestimmt. Diese im Gegensatz zu früher2) als 4R-2

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Transposable elements: Functional aspects and applications as drivers of crop innovation

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Transposable elements (TEs), which were once relegated to the status of genomic parasites, are today accepted as important agents of plant genome evolution and adaptation. This review integrates evidence pointing to their dual function as drivers of genetic diversity and instability, with a focus on their contribution to phenotypic innovation,

Upstream CB1R Regulation of β‐Adrenergic Memory Consolidation

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT Object recognition memory (ORM) plays a key role in identifying familiar items and encoding episodic information. ORM consolidation depends on β‐adrenergic receptor (βAR) signaling and is associated with increased BDNF expression in the dorsal hippocampus.

A universal method for the identification of genes encoding amatoxins and phallotoxins in poisonous mushrooms [PDF]

, 2017
Background. As the currently known diagnostic DNA targets amplified in the PCR assays for detection of poisonous mushrooms have their counterparts in edible species, there is a need to design PCR primers specific to the genes encoding amanitins and ...
