NTRC mediates the coupling of chloroplast redox rhythm with nuclear circadian clock in plant cells.

The intricate interplay between cellular circadian rhythms, primarily manifested in the chloroplast redox oscillations-characterized by diel hyperoxidation/reduction cycles of 2-Cys Peroxiredoxins-and the nuclear transcription/translation feedback loop (TTFL) machinery within plant cells, demonstrates a remarkable temporal coherence. However, the molecular mechanisms underlying the integration of these circadian rhythms remain elusive. Here, we elucidate that the chloroplast redox protein, NADPH-dependent thioredoxin reductase type-C (NTRC), modulates the integration of the chloroplast redox rhythms and nuclear circadian clocks by regulating intracellular levels of reactive oxygen species and sucrose.

Unprecedented short-circuit current density and efficiency of vacuum-deposited organic solar cells based on 8H-thieno[2',3':4,5]thieno[3,2-b] thieno[2,3-d]pyrrole.

Despite the many advantages for industrial mass production, vacuum-deposited organic solar cells (OSCs) suffer from low efficiency, primarily due to the limited molecular library of small-molecule donor and acceptor materials, which remains a significant challenge. Herein, two donor-acceptor-acceptor (D-A-A)-configured small-molecule donors, named TTBTDC and TTBTDC-F were synthesized, using 8H-thieno[2',3':4,5]thieno[3,2-b]thieno[2,3-d]pyrrole (TTP) as a new fused-ring donor unit. Benefiting from the strong electron-donating ability of the TTP moiety and the adoption of the D-A-A molecular configuration, these molecules exhibited strong visible and near-infrared absorption as well as deep-lying highest occupied molecular orbital (HOMO) energy levels.

Four new species of Simon, 1884 (Araneae, Linyphiidae) from Jiangjin District of Chongqing, China.

Four new species of the genus Simon, 1884 are described from Jiangjin, Chongqing: (♂), (♂♀), (♂♀), and (♂♀). The new species exhibit distinctive genital features, such as a bifurcated embolus tip in the male palp of and , and embolus tip unbifurcated in The epigynes display more unique characteristics, such as epigynal plate with a pit ventrally on its frontal face in and , which is absent in all other known species. Detailed descriptions, along with photographs of genital characters, somatic features, and a distribution map, are provided.

Quality Differences in Frozen Mackerel According to Thawing Method: Potential Classification via Hyperspectral Imaging.

Seafood quality preservation remains a critical focus in the food industry, particularly as the freeze-thaw process significantly impacts the freshness and safety of aquatic products. This study investigated quality changes in frozen mackerel subjected to two thawing methods, room temperature (RT) and running water (WT), and assessed the potential of hyperspectral imaging (HSI) for classifying these methods. After thawing, mackerel samples were stored at 5 °C for 21 days, with physicochemical, textural, and spectroscopic analyses tracking quality changes and supporting the development of a spectroscopic classification model.
