Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity.

Photo-Activatable RNA Switches for Optical Control of Cell-Free Protein Synthesis ↗
Abstract Programmable RNA switches enable target-dependent regulation of cell-free protein synthesis. Here, we report a photo-activatable RNA switch using photocleavable Lock DNA (pcl-Lock) to enable optical control of in vitro translation. Synthesized by solid-phase methods, pcl-Lock incorporates a coumarin-based photocleavable linker that maintains the RNA switch in an inactive state. Irradiation with 456 nm light cleaves the linker, releasing inhibition and activating translation. Light-triggered activation produced β-galactosidase, yielding approximately 4-fold and 30-fold increases in flu…

Epistatic redundancy reconciles pervasive genetic interactions with their rarity in genome-wide analyses ↗
Epistasis, the genetic interaction between loci, has long been recognized as a fundamental feature of the genetic architecture, but its importance remains controversial. This controversy stems partly from the apparent disconnect between abundant physiological epistasis observed in laboratory settings and the rarity of detectable epistatic interactions in genome-wide association studies (GWAS). Here, I introduce the concept of epistatic redundancy, whereby a focal locus interacts with multiple alternative loci rather than a single partner. Using population genetic simulations, I demonstrate tha…

Targeting CLK1 by CRISPR tools and pharmacological inhibition modulates the innate immune response and dengue virus replication ↗
Alternative splicing is a key regulatory mechanism known to be altered upon viral infection. These alterations can arise both from direct viral interference with the splicing machinery and from cellular responses such as activation of innate immunity. Here, we investigated splicing changes shared between dengue virus (DENV) infection and interferon (IFN) treatment in cultured cells, the latter serving as a model for virus-independent innate immune activation. Among the common events, we identified an increased production of non-coding mRNA isoforms from the CLK1 gene, which gives rise to a kin…

Association mapping and genome prediction reveal a complex genetic architecture for resistance to black and frosty pod rot in cacao ( Theobroma cacao L.) populations ↗
Abstract Cacao ( Theobroma cacao L.) production is severely constrained by black pod rot (BPR) and frosty pod rot (FPR), two major diseases that cause substantial yield losses across the tropics. Breeding for disease resistance remains challenging due to long generation intervals and the complex genetic control of disease responses. Here, we used genome‐wide association studies (GWASs) and genomic prediction (GP) to dissect the genetic basis of BPR and FPR resistance in an interrelated multi‐parent F 1 panel comprising 495 individuals derived from eight bi‐parental crosses. Whole‐genome sequen…

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation ↗
ABSTRACT Posttranslational sulfur incorporation into peptide backbones is increasingly reported. These efforts broaden our understanding of thioamides, which have distinct conformational and hydrogen‐bonding properties compared with amides. YcaO‐catalyzed thioamidation of the ribosomal protein uL16 reportedly occurs across thousands of Pseudomonadota. Here, we identify the cysteine desulfurase IscS, a crucial component of iron–sulfur cluster assembly, as the direct sulfur donor for uL16 thioamidation. Genetic deletion, in vitro reconstitution, kinetic analysis, sulfide scavenging, and mutation…

Structural Variants in the Human Genome Associated With Gut Microbiome and Blood Metabolic Traits With Potential Causal Links ↗
ABSTRACT Research on genetic variants affecting the gut microbiome and blood metabolites has mainly focused on single nucleotide variants (SNPs), leaving structural variants (SVs) largely unexplored. Here, we analyzed high‐coverage (∼42×) whole‐genome sequencing data from 2002 individuals and constructed a catalog of 138 859 high‐confidence SVs, including 44.3% variants not represented in public SV resources. Genome‐wide association analyses of 22 519 common SVs identified 30 microbiome‐associated and 48 metabolite‐associated SV loci, including 19 study‐wide significant associations. Notable s…

Stable isotope‐derived measurements of protein synthesis detect amino acid‐induced anabolism in skeletal muscle microtissues not captured by puromycin labelling ↗
Skeletal muscle microtissues are valuable in vitro models for studying the stimuli regulating muscle protein synthesis (MPS), the key determinant of changes in muscle mass. Differentiated between opposing posts, microtissues contain aligned, contractile myotubes, providing a controlled system for investigating the responses of skeletal muscle to nutrient and contractile stimulation. However, microtissue MPS responses to these stimuli remain under-characterized. Stable isotope-labelled amino acid tracers deliver sarcoplasmic and myofibrillar fractional synthetic rates (FSR) for MPS in human stu…

Genome-wide association analyses reveal genetic loci associated with cold responses in Miscanthus under non-acclimated and cold-acclimated conditions ↗
Miscanthus species are C4 perennial bioenergy crops with broad environmental adaptability, yet episodic freezing events can constrain establishment and productivity. We evaluated cold-response variation in a 144-accession panel comprising 73 M. sacchariflorus and 71 M. lutarioriparius accessions under non-acclimated and cold-acclimated conditions. LT50 was recalculated from the original mean relative electrical conductivity (REC) data using y = 100/[1 + a exp(bx)] and LT50 = -ln(a)/b; fits were retained when R² >= 0.80 and LT50 fell within the experimental range (-16 to 0 °C). Additional genot…

Gene functional-state covariance reveals modular structure in the Arabidopsis thaliana dispensable genome ↗
Classical multilocus theory predicts that selection acting on combinations of loci can maintain non-random associations among allelic states, causing selection to act on multilocus genotypes rather than individual alleles. Across eukaryotic species, pangenome studies have documented thousands of genes that vary in functional status between individuals, yet this variation is analyzed as if each gene evolves independently. Here we test for non-random association within the dispensable pangenome across 1,012 natural genotypes of Arabidopsis thaliana to better understand the structure and evolutio

BoNTax: a curated genome-based framework for taxonomic classification and characterization of Clostridium botulinum Group I and Clostridium sporogenes ↗
Clostridium botulinum Group I and Clostridium sporogenes are closely related genomic lineages for which historical toxin-based nomenclature can obscure species-level relationships. We developed BoNTax, a curated taxonomy-first framework that separates average nucleotide identity (ANI)-based species assignment from botulinum neurotoxin (BoNT) characterization while integrating assembly quality assessment, multilocus sequence typing (MLST), AMRFinderPlus-based detection of bont genes, other virulence-associated genes, and antimicrobial resistance genes into standardized outputs.

How to assess evidence about Biotechnology
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
