JA-responsive R2R3-type MYB transcription factor OsMYB4P confers broad-spectrum antiviral immunity in rice.

Jasmonic acid (JA) plays a critical role in antiviral defence in rice, where viral infection activates JA signalling by degrading Jasmonate ZIM domain (JAZ) proteins, thereby releasing transcription factors (TFs) to drive JA-mediated defence gene expression. While the JA-responsive TF OsMYC2 has been extensively studied in rice, the involvement of MYB TFs in JA signalling remains largely unexplored. In this study, we identified a novel JA-responsive R2R3-type MYB TF OsMYB4P.

The MYB transcription factor ClPC modulates petal color and chlorophyll accumulation in watermelon.

During the pre-anthesis stage, high chlorophyll levels in petals result in a green hue in many plants. Upon anthesis, chlorophyll degradation uncovers other pigments, thereby influencing pollinator attraction and reproductive success in insect-pollinated crops. In the watermelon accession WM109, a novel petal phenotype characterized by a yellow-green hue was observed, significantly different from the canonical yellow petal phenotype typically associated with this species.

Evolutionary-Distinct Viral Proteins Subvert Rice Broad-Spectrum Antiviral Immunity Mediated by the RAV15-MYC2 Module.

A variety of plant viruses employ different virulence strategies to achieve successful infection, resulting in abnormal plant development. However, the common pathogenicity of distinct viruses has rarely been studied. Here, it is shown that a plant-specific RAV-type transcription factor, OsRAV15, is specifically targeted by several distinct viral proteins for facilitating viral infection.

Estimating lead-attributable mortality burden by socioeconomic status in the USA.

Background: This study aimed to estimate population-level and state-level lead-attributable mortality burdens stratified by socioeconomic status (SES) class in the USA.

Methods: Based on the National Health and Nutrition Examination Survey (NHANES), we constructed individual-level SES scores from income, employment, education and insurance data. We assessed the association between the blood lead levels (BLL) and all-cause mortality by Cox regression in the NHANES cohort (n = 31 311, 4467 deaths).

Three-dimensional high-aspect-ratio microarray thick electrodes for high-rate hybrid supercapacitors.

Hybrid supercapacitors (HSCs) with facile integration and high process compatibility are considered ideal power sources for portable consumer electronics. However, as a crucial component for storing energy, traditional thin-film electrodes exhibit low energy density. Although increasing the thickness of thin films can enhance the energy density of the electrodes, it gives rise to issues such as poor mechanical stability and long electron/ion transport pathways.

Synthetic Leaves Based on Crystalline Olefin-Linked Covalent Organic Frameworks for Efficient CO Photoreduction with Water.

We report, for the first time, a new synthetic strategy for the preparation of crystalline two-dimensional olefin-linked covalent organic frameworks (COFs) based on aldol condensation between benzodifurandione and aromatic aldehydes. Olefin-linked COFs can be facilely crystallized through either a pyridine-promoted solvothermal process or a benzoic anhydride-mediated organic flux synthesis. The resultant COF leaf with high in-plane π-conjugation exhibits efficient visible-light-driven photoreduction of carbon dioxide (CO) with water (HO) in the absence of any photosensitizer, sacrificial agents, or cocatalysts.

Subnanometric Bismuth Clusters Confined in Pyrochlore-Bi Sn O Enable Remarkable CO Photoreduction.

The development of highly efficient photocatalysts for conversion of carbon dioxide (CO ) with water (H O) into chemical fuels is of great importance for energy sustainability and carbon resource utilization. Herein, we demonstrated a facile hydrothermal method for in situ construction of subnanometric Bi metallic clusters in pyrochlore-Bi Sn O frameworks, leading to the remarkable improvements of photocatalytic performances for CO reduction into CO in the absence of sacrificial reagent. More specifically, an outstanding CO evolution activity of 114.

Caloric restriction remodels the hepatic chromatin landscape and bile acid metabolism by modulating the gut microbiota.

Background: Caloric restriction (CR) has been known to promote health by reprogramming metabolism, yet little is known about how the epigenome and microbiome respond during metabolic adaptation to CR.

Results: We investigate chromatin modifications, gene expression, as well as alterations in microbiota in a CR mouse model. Collectively, short-term CR leads to altered gut microbial diversity and bile acid metabolism, improving energy expenditure.

Regulating π-Conjugation in sp -Carbon-Linked Covalent Organic Frameworks for Efficient Metal-Free CO Photoreduction with H O.

The development of sp -carbon-linked covalent organic frameworks (sp c-COFs) as artificial photocatalysts for solar-driven conversion of CO into chemical feedstock has captured growing attention, but catalytic performance has been significantly limited by their intrinsic organic linkages. Here, a simple, yet efficient approach is reported to improve the CO photoreduction on metal-free sp c-COFs by rationally regulating their intrinsic π-conjugation. The incorporation of ethynyl groups into conjugated skeletons affords a significant improvement in π-conjugation and facilitates the photogenerated charge separation and transfer, thereby boosting the CO photoreduction in a solid-gas mode with only water vapor and CO .

Discovery of aphid-transmitted Rice tiller inhibition virus from native plants through metagenomic sequencing.

A major threat to rice production is the disease epidemics caused by insect-borne viruses that emerge and re-emerge with undefined origins. It is well known that some human viruses have zoonotic origins from wild animals. However, it remains unknown whether native plants host uncharacterized endemic viruses with spillover potential to rice (Oryza sativa) as emerging pathogens.

Melon yellow-green plant (Cmygp) encodes a Golden2-like transcription factor regulating chlorophyll synthesis and chloroplast development.

A SNP mutation in CmYGP gene encoding Golden2-like transcription factor is responsible for melon yellow-green plant trait. Chlorophylls are essential and beneficial substances for both plant and human health. Identifying the regulatory network of chlorophyll is necessary to improve the nutritional quality of fruits.

Association of Endocrine-Disrupting Chemicals with All-Cause and Cause-Specific Mortality in the U.S.: A Prospective Cohort Study.

Wide exposure to endocrine-disrupting chemicals (EDCs) poses a great risk on human health. However, few large-scale cohort studies have comprehensively estimated the association between EDCs exposure and mortality risk. This study aimed to investigate the association of urinary EDCs exposure with mortality risk and quantify attributable mortality and economic loss.

Molecular cytogenetic map visualizes the heterozygotic genome and identifies translocation chromosomes in Citrus sinensis.

Citrus sinensis is the most cultivated and economically valuable Citrus species in the world, whose genome has been assembled by three generation sequencings. However, chromosome recognition remains a problem due to the small size of chromosomes, and difficulty in differentiating between pseudo and real chromosomes because of a highly heterozygous genome. Here, we employ fluorescence in situ hybridization (FISH) with 9 chromosome painting probes, 30 oligo pools, and 8 repetitive sequences to visualize 18 chromosomes.

PlantBind: an attention-based multi-label neural network for predicting plant transcription factor binding sites.

Identification of transcription factor binding sites (TFBSs) is essential to understanding of gene regulation. Designing computational models for accurate prediction of TFBSs is crucial because it is not feasible to experimentally assay all transcription factors (TFs) in all sequenced eukaryotic genomes. Although many methods have been proposed for the identification of TFBSs in humans, methods designed for plants are comparatively underdeveloped.

Association between exposure to cadmium and risk of all-cause and cause-specific mortality in the general US adults: A prospective cohort study.

Background: Cadmium has been suggested to accumulate in the body over a lifetime, posing a great threat to human health. So far, few studies have studied the association between cadmium exposure and long-term health outcomes in adults.

Objectives: To investigate the risk of mortality with blood cadmium level in adults (participants of NHANES, 1999-2014).

Association between per- and polyfluoroalkyl substances and risk of gestational diabetes mellitus.

Background: Existing evidence suggests that perfluoroalkyl and polyfluoroalkyl substances (PFASs) exposure might contribute to the incidence of gestational diabetes mellitus (GDM). This study aimed to perform a meta-analysis to identify the association between PFAS and the risk of GDM.

Methods: We systematically searched PubMed, Ovid, Cochrane Library, and Web of Science databases for appropriate articles about the association between PFASs exposure and the risk of GDM before September 28, 2020.

Melon short internode (CmSi) encodes an ERECTA-like receptor kinase regulating stem elongation through auxin signaling.

Plant height is one of the most important agronomic traits that directly determines plant architecture, and compact or dwarf plants can allow for increased planting density and land utilization as well as increased lodging resistance and economic yield. At least four dwarf/semidwarf genes have been identified in different melon varieties, but none of them have been cloned, and little is known about the molecular mechanisms underlying internode elongation in melon. Here, we report map-based cloning and functional characterization of the first semidwarf gene short internode (Cmsi) in melon, which encodes an ERECTA-like receptor kinase regulating internode elongation.

Development and application of oligonucleotide-based chromosome painting for chromosome 4D of Triticum aestivum L.

Chromosome painting is a useful technique for distinguishing specific chromosomes (fragments), elucidating the genetic relationships of different genomes or chromosomes, and identifying chromosomal rearrangements. The development of chromosome- or genome-specific probes is fundamental for chromosome painting. The possibility for developing such probes specifically painting homoeologous chromosomes in allopolyploid species has been questioned since that chromosomes belonging to the same homoeologous group share highly conserved sequences.

H Metabolism revealed by metagenomic analysis of subglacial sediment from East Antarctica.

Subglacial ecosystems harbor diverse chemoautotrophic microbial communities in areas with limited organic carbon, and lithological H produced during glacial erosion has been considered an important energy source in these ecosystems. To verify the H-utilizing potential there and to identify the related energy-converting metabolic mechanisms of these communities, we performed metagenomic analysis on subglacial sediment samples from East Antarctica with and without H supplementation. Genes coding for several [NiFe]-hydrogenases were identified in raw sediment and were enriched after H incubation.
