Low temperature inhibits anthocyanin accumulation in strawberry fruit by activating FvMAPK3-induced phosphorylation of FvMYB10 and degradation of Chalcone Synthase 1.

Low temperature causes poor coloration of strawberry (Fragaria sp.) fruits, thus greatly reducing their commercial value. Strawberry fruits accumulate anthocyanins during ripening, but how low temperature modulates anthocyanin accumulation in plants remains largely unknown. We identified MITOGEN-ACTIVATED PROTEIN KINASE3 (FvMAPK3) as an important negative regulator of anthocyanin accumulation that mediates the poor coloration of strawberry fruits in response to low temperature. FvMAPK3 activity was itself induced by low temperature, leading to the repression of anthocyanin accumulation via two mechanisms. Activated FvMAPK3 acted as the downstream target of MAPK KINASE4 (FvMKK4) and SUCROSE NONFERMENTING1-RELATED KINASE2.6 (FvSnRK2.6) to phosphorylate the transcription factor FvMYB10 and reduce its transcriptional activity. In parallel, FvMAPK3 phosphorylated CHALCONE SYNTHASE1 (FvCHS1) to enhance its proteasome-mediated degradation. These results not only provide an important reference to elucidate the molecular mechanisms underlying low-temperature-mediated repression of anthocyanin accumulation in plants, but also offer valuable candidate genes for generating strawberry varieties with high tolerance to low temperature and good fruit quality.

Highly Flexible K-Intercalated MnO2 /Carbon Membrane for High-Performance Aqueous Zinc-Ion Battery Cathode.

The layered MnO2 is intensively investigated as one of the most promising cathode materials for aqueous zinc-ion batteries (AZIBs), but its commercialization is severely impeded by the challenging issues of the inferior intrinsic electronic conductivity and undesirable structural stability during the charge-discharge cycles. Herein, the lab-prepared flexible carbon membrane with highly electrical conductivity is first used as the matrix to generate ultrathin δ-MnO2 with an enlarged interlayer spacing induced by the K+ -intercalation to potentially alleviate the structural damage caused by H+ /Zn2+ co-intercalation, resulting in a high reversible capacity of 190 mAh g-1 at 3 A g-1 over 1000 cycles. The in situ/ex-situ characterizations and electrochemical analysis confirm that the enlarged interlayer spacing can provide free space for the reversible deintercalation/intercalation of H+ /Zn2+ in the structure of δ-MnO2 , and H+ /Zn2+ co-intercalation mechanism contributes to the enhanced charge storage in the layered K+ -intercalated δ-MnO2 . This work provides a plausible way to construct a flexible carbon membrane-based cathode for high-performance AZIBs.

Surface Reconstruction of Co4N Coupled with CeO2 toward Enhanced Alkaline Oxygen Evolution Reaction.

Constructing the active interface in a heterojunction electrocatalyst is critical for the electron transfer and intermediate adsorption (O*, OH*, and HOO*) in alkaline oxygen evolution reaction (OER) but still remains challenging. Herein, a CeO2/Co4N heterostructure is rationally synthesized through the direct calcination of Ce[Co(CN)6], followed by thermal nitridation. The in situ electrochemically generated CoOOH on the surface of Co4N serves as the active site for the OER, and the coupled CeO2 with oxygen vacancy can optimize the energy barrier of intermediate reactions of the OER, which simultaneously boosts the OER performance. Besides, electrochemical measurement results demonstrate that oxygen vacancies in CeO2 and optimized absorption free energy originating from the electron transfer between CeO2 and CoOOH contribute to enhanced OER kinetics. This work provides new insight into regulating the interface heterostructure to rationally design efficient OER electrocatalysts under alkaline conditions.

Genome-Wide Identification, Characterization, and Expression Analysis of Tubby-like Protein (TLP) Gene Family Members in Woodland Strawberry (Fragaria vesca).

Tubby-like proteins (TLPs) play important roles in plant growth and development and in responses to abiotic stress. However, TLPs in strawberry remain poorly studied. In this study, eight TLPs were identified in woodland strawberry (Fragaria vesca subspecies vesca 'Ruegen'). Protein structure analysis revealed that the structure of FvTLPs is highly conserved, but evolutionary and gene structure analyses revealed that the evolutionary pattern of FvTLP family members differs from that of their orthologous genes in Arabidopsis, poplar, and apple. Subcellular localization assays revealed that FvTLPs were localized to the nucleus and plasma membrane. FvTLPs showed no transcriptional activity. Yeast two-hybrid assays revealed that FvTLPs interact with specific FvSKP1s. The expression patterns of FvTLPs in different tissues and under various abiotic stresses (salt, drought, cold, and heat) and hormone treatments (ABA (abscisic acid) and MeJA (methyl jasmonate)) were determined. The expression patterns of FvTLPs indicated that they play a role in regulating growth and development and responses to abiotic stress in F. vesca. The GUS (beta-glucuronidase) activity of FvTLP1pro::GUS plants in GUS activity assays increased under salt and drought stress and abscisic acid treatment. The results of this study provide new insights into the molecular mechanisms underlying the functions of TLPs.

Holey Ruthenium Nanosheets with Moderate Aluminum Modulation toward Hydrogen Evolution.

Theoretical calculations reveal that aluminum (Al) doping can effectively modulate the electronic structures of 2D ruthenium (Ru) catalysts. Moderate Al incorporation can endow Ru nanosheets with more delocalized electrons and optimal hydrogen adsorption Gibbs free energy, providing opportunities to achieve improved hydrogen evolution performance. Thus, Al-doped Ru nanosheets have been synthesized by a solvothermal strategy, in which they exhibit holey nanosheet structures and have more active sites exposed on the basal plane. The characterizations unraveling the Ru structure can be well maintained, and electrochemical measurements confirm the appropriate amount of Al modulation that can extremely enhance its hydrogen evolution activity.

The Enhancement of the Catalytic Oxidation of CO on Ir/CeO2 Nanojunctions.

Heterogeneous catalysts facilitate various chemical reactions through the changing of their surface charge density. Herein, we demonstrate an interface engineering strategy to enhance the Ir catalytic performance for oxidation of CO by constructing Ir/CeO2 nanojunctions using a wet chemical reduction process. The as-prepared Ir/CeO2 nanojunctions show a complete CO conversion temperature (T100) of 110 °C under 1 vol % CO and retains long-term durability even after 24 h. The Ir atoms and CeO2 supports were connected by O atoms, which changes the surface electronic structure of Ir atoms. DFT calculations demonstrate that the significant increase in electron density at the interface between Ir and CeO2 plays a pivotal role in the enhancement of CO oxidation.

FaMYB44.2, a transcriptional repressor, negatively regulates sucrose accumulation in strawberry receptacles through interplay with FaMYB10.

Sugar and acid metabolism are critical for fruit ripening and quality formation, but the underlying regulatory mechanisms are largely unknown. Here, we identified a transcriptional repressor, FaMYB44.2, that regulates sugar and acid accumulation in strawberry (Fragaria × ananassa 'Benihoppe') receptacles. We transiently expressed FaMYB44.2 in strawberry fruit and conducted metabolic and molecular analyses to explore the role of FaMYB44.2 in sugar and acid accumulation in strawberry. We found that FaMYB44.2 negatively regulates soluble sugar accumulation and malic acid content and represses the expression of numerous structural genes, including FaSPS3, a key gene in sucrose accumulation. From the white fruit stage onwards, the repressive effect of FaMYB44.2 on FaSPS3 is reversed by FaMYB10, which positively regulates anthocyanin accumulation. Our results indicate that FaMYB10 suppresses FaMYB44.2 expression; weakens the interaction between FaMYB44.2 and its co-repressor, FabHLH3; and cooperates with FabHLH3 to activate the expression of FaSPS3. The interplay between FaMYB10 and FaMYB44.2 results in sucrose accumulation in ripe strawberry fruits. In addition, the repressive effect of FaMYB44.2 on sucrose accumulation is enhanced by jasmonic acid. This study provides new insights into the regulatory mechanisms of sucrose accumulation and sheds light on the interplay between regulatory proteins during strawberry fruit ripening and quality formation.

Facile Preparation of Amorphous Fe-Co-Ni Hydroxide Arrays: A Highly Efficient Integrated Electrode for Water Oxidation.

Facile and fast synthesis of functional materials with high catalytic activity is highly demanded to meet the industrial production and applications such as electrolysis. In this study, Ni foam is employed as the current collector and Ni source, which is dipped into the mixture of Fe and Co metal ions solution at room temperature for several minutes, to in situ grow Fe-Co-Ni hydroxide arrays and construct the three-dimensional integrated electrode. This short-time preparation at room temperature is beneficial to avoid the rapid growth of the generated primary nanocrystallites and cause intimate interactions between Fe, Co, and Ni atoms. The obtained self-supported and vertically aligned Fe-Co-Ni hydroxides present an amorphous phase, which exhibit high activity with low overpotentials of 212 mV at 10 mA cm-2 and 319 mV at 100 mA cm-2, associated with a small Tafel slope of 52 mV dec-1 toward the oxygen evolution reaction.

SUCROSE NONFERMENTING1-RELATED PROTEIN KINASE2.6, an ortholog of OPEN STOMATA1, is a negative regulator of strawberry fruit development and ripening.

Whereas the regulatory mechanisms that direct fruit ripening have been studied extensively, little is known about the signaling mechanisms underlying this process, especially for nonclimacteric fruits. In this study, we demonstrated that a SUCROSE NONFERMENTING1-RELATED PROTEIN KINASE2, designated as FaSnRK2.6, is a negative regulator of fruit development and ripening in the nonclimacteric fruit strawberry (Fragaria × ananassa) and can also mediate temperature-modulated strawberry fruit ripening. FaSnRK2.6 was identified as an ortholog of OPEN STOMATA1. Levels of FaSnRK2.6 transcript rapidly decreased during strawberry fruit development and ripening. FaSnRK2.6 was found to be capable of physically interacting with strawberry ABSCISIC ACID INSENSITIVE1, a negative regulator in strawberry fruit ripening. RNA interference-induced silencing of FaSnRK2.6 significantly promoted fruit ripening. By contrast, overexpression of FaSnRK2.6 arrested fruit ripening. Strawberry fruit ripening is highly sensitive to temperature, with high temperatures promoting ripening and low temperatures delaying it. As the temperature increased, the level of FaSnRK2.6 expression declined. Furthermore, manipulating the level of FaSnRK2.6 expression altered the expression of a variety of temperature-responsive genes. Taken together, this study demonstrates that FaSnRK2.6 is a negative regulator of strawberry fruit development and ripening and, furthermore, that FaSnRK2.6 mediates temperature-modulated strawberry fruit ripening.

Enhancing Electrocatalytic CO2-to-CO Conversion by Weakening CO Binding through Nitrogen Integration in the Metallic Fe Catalyst.

Metallic iron (Fe) typically demonstrates the unfavorable catalytic activity for the CO2 reduction reaction (CO2RR), mainly attributed to the excessively strong binding of CO products on Fe sites. Toward this end, we employed an effective approach involving electronic structure modulation through nitrogen (N) integration to enhance the performance of the CO2RR. Here, an efficient catalyst has been developed, composed of N-doped metallic iron (Fe) nanoparticles encapsulated in a porous N-doped carbon framework. Notably, this N-integrated Fe catalyst displays significantly enhanced performance in the electrocatalytic reduction of CO2, yielding the highest CO Faradaic efficiency of 97.5% with a current density of 6.68 mA cm-2 at -0.7 V versus the reversible hydrogen electrode. The theoretical calculations, combined with the in situ attenuated total reflection surface-enhanced infrared absorption spectroscopy study, reveal that N integration modulates the electron density around Fe, resulting in the weakening of the binding strength between the Fe active sites and *CO intermediates, consequently promoting the desorption of CO and the overall CO2RR process.

Different acupotomy for stenosing tenosynovitis: A protocol for systematic review and network meta-analysis.

BACKGROUND: Stenosing tenosynovitis (STS) is a chronic aseptic inflammation caused by mechanical friction. The main clinical manifestations are local pain and limited activity of the affected parts, which reduce people's quality of life. The clinical effect of acupotomy in the treatment of STS is significant, and the operation is simple and the side effect is small. But there are many kinds of acupotomology, and there is a lack of comparative study between different Acupotomology. In this study, the effectiveness of 4 commonly used needle knife therapies (v-knife, oblique knife, crochet knife, flat knife) was ranked by the method of network meta. METHODS: CNKI, Wanfang, VIP, Sinomed, PubMed, and Cochrane Library were searched to collect randomized controlled trials of v-knife, oblique knife, crochet knife, and flat knife in the treatment of STS. The search time limit is from the date of establishment to October 15, 2021. Revman5.3, gemtc 0.14.3, and stata14.2 were used for data analysis, and Cochrane bias risk assessment tool was used to screen and evaluate the quality of included literatures. CONCLUSION: Objective to provide evidence-based medicine evidence for clinical selection of the best needle knife treatment scheme for STS.

Optimizing the Interlayer Spacing of Heteroatom-Doped Carbon Nanofibers toward Ultrahigh Potassium-Storage Performances.

Precise control over the interlayer spacing for K+ intercalation is an effective approach to boost the potassium-storage performances in carbonaceous materials. Herein, we first found that the optimal interlayer spacing for K+ intercalation is around 0.38 nm for N, O codoped carbon nanofibers (NOCNs), displaying a reversible capacity of 627 mAh g-1 at 0.1 A g-1 after 200 cycles, excellent rate capability (123 mAh g-1 at 20 A g-1), and ultrastable cycling stability (262 mAh g-1 at 5 A g-1 after 10 000 cycles). Such good potassium-storage performances have never been reported in carbonaceous materials. The theoretical calculations and electrochemical studies reveal that the optimal interlayer spacing and N, O heteroatom-induced active sites work together to provide an intercalation-adsorption mechanism for storing K+ in carbonaceous materials. This work facilitates the understanding of the role of the critical interlayer spacing for K+ intercalation in carbonaceous materials.

Chromosome-level genome assembly of Fragaria pentaphylla using PacBio and Hi-C technologies.

Fragaria pentaphylla, a wild diploid quinquefoliolate species of Fragaria, is native to Southwest China. It has two morphs of red and white fruit color in nature and has characteristics of unique fragrance and resistance, which made it not only a valuable breeding material but also a potential model plant for molecular function researches. Here, we generate a high-quality chromosome-level genome assembly of a F. pentaphylla accession, BAAFS-FP039 employing a combination of PacBio Long-Read Sequencing, Illumina Short-Read Sequencing, and Hi-C Sequencing. The assembled genome contained 256.74 Mb and a contig N50 length of 32.38 Mb, accounting for 99.9% of the estimated genome (256.77 Mb). Based on Hi-C data, seven pseudo-chromosomes of F. pentaphylla-FP039 genome were assembled, covering 99.39% of the genome assembly. The genome was composed of 44.61% repetitive sequences and 29,623 protein-coding genes, 97.62% of protein-coding genes could be functionally annotated. Phylogenetic and chromosome syntenic analysis revealed that F. pentaphylla-FP039 was closely related to F. nubicola. This high-quality genome could provides fundamental molecular resources for evolutionary studies, breeding efforts, and exploring the unique biological characteristics of F. pentaphylla.

Genome-Wide Analysis of Ascorbic Acid Metabolism Related Genes in Fragaria × ananassa and Its Expression Pattern Analysis in Strawberry Fruits.

Ascorbic acid (AsA) is an important antioxidant for scavenging reactive oxygen species and it is essential for human health. Strawberry (Fragaria × ananassa) fruits are rich in AsA. In recent years, strawberry has been regarded as a model for non-climacteric fruit ripening. However, in contrast to climacteric fruits, such as tomato, the regulatory mechanism of AsA accumulation in strawberry fruits remains largely unknown. In this study, we first identified 125 AsA metabolism-related genes from the cultivated strawberry "Camarosa" genome. The expression pattern analysis using an available RNA-seq data showed that the AsA biosynthetic-related genes in the D-mannose/L-galactose pathway were downregulated remarkably during fruit ripening which was opposite to the increasing AsA content in fruits. The D-galacturonate reductase gene (GalUR) in the D-Galacturonic acid pathway was extremely upregulated in strawberry receptacles during fruit ripening. The FaGalUR gene above belongs to the aldo-keto reductases (AKR) superfamily and has been proposed to participate in AsA biosynthesis in strawberry fruits. To explore whether there are other genes in the AKR superfamily involved in regulating AsA accumulation during strawberry fruit ripening, we further implemented a genome-wide analysis of the AKR superfamily using the octoploid strawberry genome. A total of 80 FaAKR genes were identified from the genome and divided into 20 subgroups based on phylogenetic analysis. These FaAKR genes were unevenly distributed on 23 chromosomes. Among them, nine genes showed increased expression in receptacles as the fruit ripened, and notably, FaAKR23 was the most dramatically upregulated FaAKR gene in receptacles. Compared with fruits at green stage, its expression level increased by 142-fold at red stage. The qRT-PCR results supported that the expression of FaAKR23 was increased significantly during fruit ripening. In particular, the FaAKR23 was the only FaAKR gene that was significantly upregulated by abscisic acid (ABA) and suppressed by nordihydroguaiaretic acid (NDGA, an ABA biosynthesis blocker), indicating FaAKR23 might play important roles in ABA-mediated strawberry fruit ripening. In a word, our study provides useful information on the AsA metabolism during strawberry fruit ripening and will help understand the mechanism of AsA accumulation in strawberry fruits.

FaAKR23 Modulates Ascorbic Acid and Anthocyanin Accumulation in Strawberry (Fragaria × ananassa) Fruits.

Strawberry (Fragaria × ananassa) fruits are rich in ascorbic acid (AsA) and anthocyanin, which are essential antioxidants for human health. However, the underlying regulatory mechanism of these antioxidant accumulation, especially AsA accumulation in strawberry fruits, remains largely unknown. In this study, we identified FaAKR23 was a regulator of AsA and anthocyanin accumulation. We transiently expressed FaAKR23 in strawberry fruits and conducted metabolic and molecular analyses to explore the role of FaAKR23 in AsA and anthocyanin accumulation. Transient silencing of FaAKR23 (FaAKR23-RNAi) in strawberry fruits significantly decreased the AsA and anthocyanin contents compared with control (empty vector-RNAi, EV-RNAi). Correspondingly, expression of some structural genes and regulatory factors involved in these two antioxidants' accumulation was dramatically repressed. In addition, transcriptome analysis of EV-RNAi and FaAKR23-RNAi fruits suggested that FaAKR23 was also involved in starch and sucrose metabolism as well as plant-pathogen interaction. Overall, these results not only provide the coordinated regulatory function of FaAKR23 on AsA and anthocyanin accumulation but also offer a promising candidate gene for strawberry breeding with high antioxidants.

Combined transcriptomic and metabolomic analysis reveals a role for adenosine triphosphate-binding cassette transporters and cell wall remodeling in response to salt stress in strawberry.

Strawberry (Fragaria × ananassa Duch) are sensitive to salt stress, and breeding salt-tolerant strawberry cultivars is the primary method to develop resistance to increased soil salinization. However, the underlying molecular mechanisms mediating the response of strawberry to salinity stress remain largely unknown. This study evaluated the salinity tolerance of 24 strawberry varieties, and transcriptomic and metabolomic analysis were performed of 'Sweet Charlie' (salt-tolerant) and 'Benihoppe' (salt-sensitive) to explore salt tolerance mechanisms in strawberry. Compared with the control, we identified 3412 differentially expressed genes (DEGs) and 209 differentially accumulated metabolites (DAMs) in 'Benihoppe,' and 5102 DEGs and 230 DAMs in 'Sweet Charlie.' DEGs Gene Ontology (GO) enrichment analyses indicated that the DEGs in 'Benihoppe' were enriched for ion homeostasis related terms, while in 'Sweet Charlie,' terms related to cell wall remodeling were over-represented. DEGs related to ion homeostasis and cell wall remodeling exhibited differential expression patterns in 'Benihoppe' and 'Sweet Charlie.' In 'Benihoppe,' 21 ion homeostasis-related DEGs and 32 cell wall remodeling-related DEGs were upregulated, while 23 ion homeostasis-related DEGs and 138 cell wall remodeling-related DEGs were downregulated. In 'Sweet Charlie,' 72 ion homeostasis-related DEGs and 275 cell wall remodeling-related DEGs were upregulated, while 11 ion homeostasis-related DEGs and 20 cell wall remodeling-related DEGs were downregulated. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses showed only four KEGG enriched pathways were shared between 'Benihoppe' and 'Sweet Charlie,' including flavonoid biosynthesis, phenylalanine metabolism, phenylpropanoid biosynthesis and ubiquinone, and other terpenoid-quinone biosynthesis. Integrating the results of transcriptomic and metabolomics analyses showed that adenosine triphosphate-binding cassette (ABC) transporters and flavonoid pathway genes might play important roles in the salt stress response in strawberry, and DAMs and DEGs related to ABC transporter and flavonoid pathways were differentially expressed or accumulated. The results of this study reveal that cell wall remodeling and ABC transporters contribute to the response to salt stress in strawberry, and that related genes showed differential expression patterns in varieties with different salt tolerances. These findings provide new insights into the underlying molecular mechanism of strawberry response to salt stress and suggest potential targets for the breeding of salt-tolerant strawberry varieties.

Converting poly(ethylene terephthalate) waste into carbon microspheres in a supercritical CO2 system.

Well-shaped carbon spheres in micrometer dimensions were prepared by pyrolyzing postconsumer poly(ethylene terephthalate) (PET) in supercritical carbon dioxide at 500-650 °C for 3 h. It was also found that the yield of carbon microspheres increased as the reaction temperature increased and the reaction time was prolonged. Carbon microspheres were obtained in 47.5% yield as the reaction occurred at 650 °C for 9 h. A high-pressure carbonization mechanism of aromatic hydrocarbons decomposed from PET waste was proposed according to gas chromatography combined with mass spectrometry analysis. One possible application of the carbon microspheres as a negative electrode material for lithium ion batteries was evaluated.

Heteroatom-doped carbon materials with interconnected channels as ultrastable anodes for lithium/sodium ion batteries.

Carbon materials have been extensively investigated as promising negative electrode materials for lithium/sodium ion batteries. However, most common carbon materials always suffer from limitations in regards to high reversible capacity and long-term cycling stability because of their low theoretical specific capacities and sluggish kinetics. Herein, we report a facile MOF-derived strategy for the synthesis of nitrogen/oxygen co-doped porous carbon polyhedra (NOPCP) with abundant channel-connected cavities with their inner surface decorated with a large number of N and O atoms, which can provide a large number of active sites (defects and edge doping sites) for the sorption of Li+/Na+. These cavities can also be considered as "ponds" where the electrolyte is stored, which shortens the diffusion distance of ions during the discharge/charge process. When evaluated as an anode material for LIBs, NOPCP-600 delivers a high reversible capacity of 1663 mA h g-1 at 0.1 A g-1 after 120 cycles and superior cycling stability with a capacity of 667 mA h g-1 after 1000 cycles at 2 A g-1. For SIBs, NOPCP-600 delivers a high reversible capacity of 313 mA h g-1 at 0.1 A g-1 after 100 cycles and an excellent long-term cycling stability of 228 mA h g-1 at 1 A g-1 after 2000 cycles.

Boosting the K+-adsorption capacity in edge-nitrogen doped hierarchically porous carbon spheres for ultrastable potassium ion battery anodes.

Although carbon materials have great potential for potassium ion battery (KIB) anodes due to their structural stability and abundant carbon-containing resources, the limited K+-intercalated capacity impedes their extensive applications in energy storage devices. Current research studies focus on improving the surface-induced capacitive behavior to boost the potassium storage capacity of carbon materials. Herein, we designed edge-nitrogen (pyridinic-N and pyrrolic-N) doped carbon spheres with a hierarchically porous structure to achieve high potassium storage properties. The electrochemical tests confirmed that the edge-nitrogen induced active sites were conducive for the adsorption of K+, and the hierarchical porous structure promoted the generation of stable solid electrolyte interphase (SEI) films, both of which endow the resulting materials with a high reversible capacity of 381.7 mA h g-1 at 0.1 A g-1 over 200 cycles and an excellent rate capability of 178.2 mA h g-1 at 5 A g-1. Even at 5 A g-1, the long-term cycling stability of 5000 cycles was achieved with a reversible capacity of 190.1 mA h g-1. This work contributes to deeply understand the role of the synergistic effect of edge-nitrogen induced active sites and the hierarchical porous structure in the potassium storage performances of carbon materials.
