Applications of visible spectral imaging technology for pigment identification of colored relics

Heritage Science
Identifying pigments from colored relics is essential for their color restoration and for facsimile creation. A workflow for identifying pigment information is constructed based on visible spectral imaging technology, aligned with the drawing process of ...

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

Advanced Science, EarlyView.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

Advanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

Advanced Science, EarlyView.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...
