Synthetic Peptide Inhibition of Trypsin-Like Proteases in Spodoptera frugiperda (Lepidoptera: Noctuidae): Evaluating the Influence of Gut Microbiota. [PDF]

Arch Insect Biochem Physiol
Synthetic peptides (GORE1 and GORE2) inhibit trypsin‐like proteases in Spodoptera frugiperda, impairing digestion and nutritional performance. Microbiota disruption did not markedly alter enzymatic inhibition but modulated certain developmental responses.

Phytochemical diversity and seasonality are associated with a critical transition in plant-herbivore network structure. [PDF]

Ecology
Abstract Understanding critical transitions in ecological systems is fundamental for addressing various natural phenomena, from population outbreaks to sudden ecosystem collapses. Ecological interactions are key drivers of these transitions, and theory suggests that the networks formed by these interactions can undergo their own critical transition. By

Urine-Derived iPSC Neurospheres Uncover Proteomic Correlates of Clinical Severity in Dravet Syndrome. [PDF]

J Neurochem
Urine epithelial cells from Dravet syndrome (DS) patients carrying distinct SCN1A variants were reprogrammed into induced pluripotent stem cells (iPSCs) and differentiated into neural stem cells (NSCs) to generate patient‐derived neurospheres. Three neurosphere lines were analyzed in biological triplicates using isobaric quantitative proteomics ...

Ecological and Historical Correlates of Taxonomic, Phylogenetic, and Functional Diversity of Amphibians in South American Rainforests and Savannas. [PDF]

Ecol Evol
This study identifies the key drivers of anuran amphibian diversity (taxonomic, functional, and phylogenetic) across South America's Cerrado, Amazonia, and Atlantic Rainforest. Although taxonomic and phylogenetic diversity consistently increased with long‐term climatic stability in all regions, functional diversity was primarily influenced by current ...

A Hanks-type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation. [PDF]

FEBS J
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...
