The cleavage of C–O bonds presents the crucial step for realizing depolymerization lignin. Herein, we report that Ni nanoparticles (NiNPs) supported on CeO2 with oxygen vacancies (Ov) show high activity and selectivity in hydrogenolysis diphenyl ether (DPE, a lignin model compound), while single-site (SSNi) is nearly inactive reaction. Temperature-programmed desorption (TPD) demonstrates both DPE H2 can be adsorbed activated NiNPs. Density functional theory (DFT) calculation further...
Abstract Upgrading of polyethylene terephthalate (PET) waste into valuable oxygenated molecules is a fascinating process, yet it remains challenging. Herein, we developed two‐step strategy involving methanolysis PET to dimethyl (DMT), followed by hydrogenation DMT produce the high‐valued chemical methyl p‐methyl benzoate (MMB) using fixed‐bed reactor and Cu/ZrO 2 catalyst. Interestingly, discovered phase structure ZrO significantly regulates selectivity products. Cu supported on monoclinic...
Abstract Pollen tubes extend rapidly via tip growth. This process depends on a dynamic actin cytoskeleton, which has been implicated in controlling organelle movements, cytoplasmic streaming, vesicle trafficking, and cytoplasm organization pollen tubes. In this update review, we describe the progress understanding regulation of cytoskeleton function traffic We also discuss interplay between ion gradients that regulates spatial arrangement dynamics filaments Finally, several signaling...
Abstract Actin cables in pollen tubes serve as molecular tracks for cytoplasmic streaming and organelle movement are formed by actin bundling factors like villins fimbrins. However, the precise mechanisms which generated maintained remain largely unknown. Fimbrins comprise a family of five members Arabidopsis thaliana. Here, we characterized fimbrin isoform, FIMBRIN5 (FIM5). Our results show that FIM5 is required organization cytoskeleton grains tubes, loss-of-function associates with delay...
Abstract Pollen tubes deliver sperms to the ovule for fertilization via tip growth. The rapid turnover of F-actin in pollen tube tips plays an important role this process. In study, we demonstrate that Arabidopsis thaliana RIC1, a member ROP-interactive CRIB motif-containing protein family, regulates growth its severing activity. Knockout RIC1 enhanced elongation, while overexpression dramatically reduced Pharmacological analysis indicated affected dynamics tubes. vitro biochemical assays...
The organization of the actin cytoskeleton has been implicated in sclerenchyma development. However, molecular mechanisms linking to this process remain poorly understood. In particular, there have no studies showing that direct genetic manipulation affects Villins belong villin/gelsolin/fragmin superfamily and are versatile actin-modifying proteins. Several recent villins tip growth single cells, but how act multicellular plant development remains largely unknown. Here, we found two closely...
Significance The current study reveals the functions of FAF1 in protecting cells from ferroptosis, a novel cell death pathway triggered by PUFA peroxidation. In absence FAF1, cultured and mice are extremely sensitive to ferroptosis when exposed physiological levels PUFAs. Mechanistically, sequesters PUFAs into hydrophobic core global structure that limits their access positively charged Fe 2+ , which catalyzes peroxidation reaction. These observations suggest FAF1-mediated protection plays...
Dihydromyricetin (DHM), a flavonoid in vine tea, has many pharmacological activities, including anti-inflammatory and antibacterial effects. Lipopolysaccharide is the key inducer of inflammation avian pathogenic Escherichia coli (E. coli) infection; however, effect DHM on E. lipopolysaccharide-induced hepatic injury remains unknown. The present study aimed to explore role NLRP3 inflammasome possible protective mechanisms against chickens. results showed that when chickens were administered...
The actin cytoskeleton is increasingly recognized as a major regulator of pollen tube growth. Actin filaments have distinct distribution patterns and dynamic properties within different regions the tube. Apical are highly crucial for However, how apical generated properly constructed remains an open question. Here we showed that Arabidopsis fimbrin5 (FIM5) decorates filamentous structures throughout entire but apically concentrated. disorganized to degrees in tubes fim5 loss-of-function...
Abstract Developing an efficient strategy to replace the conventional synthesis method for producing isoindolinone (IIO) scaffold, a crucial structural motif constructing pharmaceutical molecules, remains be great challenge. Herein, single‐atom Pd/TiO 2 tandem catalysis has been developed IIO scaffold by using readily available phthalic anhydride (PA), ammonia, and H . The catalyst demonstrates superior catalytic performance, achieving PA conversion of 99 %, selectivity 91 turnover frequency...
How actin-bundling factors cooperatively regulate shank-localized actin bundles remains largely unexplored. Here we demonstrate that FIM5 and PLIM2a/PLIM2b decorate loss of function PLIM2a and/or PLIM2b suppresses phenotypes associated with fim5 mutants. Specifically, knockout partially the disorganized bundle intracellular trafficking phenotype in pollen tubes. generates thick but loosely packed bundles, whereas thin tight tend to be cross-linked into networks vitro. Furthermore, compete...
Several studies have revealed that actin depolymerizing factors (ADFs) participate in plant defence responses; however, the functional mechanisms appear intricate and need further exploration. In this study, we identified an ADF6 gene upland cotton (designated as GhADF6) is evidently involved cotton's response to fungal pathogen Verticillium dahliae. GhADF6 binds filaments possesses severing activities vitro vivo. When root (the site of fungus invasion) was inoculated with pathogen,...

The full Poincaré (FP) beam, encompassing all possible polarization states in its beam cross-section, has demonstrated advantages various applications. However, conventional FP beams are typically considered as spatially fully coherent, rendering them sensitive to disturbances the propagation path and susceptible speckle effects. In this work, we propose an alternative approach synthesize optical with a state through spatial coherence engineering of partially coherent beam. process, is...
