Identification of QTNs and Their Candidate Genes for Boll Number and Boll Weight in Upland Cotton.

Genome-wide association study (GWAS) has identified numerous significant loci for boll number (BN) and boll weight (BW), which play an essential role in cotton ( spp.) yield. The North Carolina design II (NC II) genetic mating population exhibits a greater number of genetic variations than other populations, which may facilitate the identification of additional genes.

FastBiCmrMLM: a fast and powerful compressed variance component mixed logistic model for big genomic case-control genome-wide association study.

Large sample datasets have been regarded as the primary basis for innovative discoveries and the solution to missing heritability in genome-wide association studies. However, their computational complexity cannot consider all comprehensive effects and all polygenic backgrounds, which reduces the effectiveness of large datasets. To address these challenges, we included all effects and polygenic backgrounds in a mixed logistic model for binary traits and compressed four variance components into two.

Reticular Modulation of Piezofluorochromic Behaviors in Organic Molecular Cages by Replacing Non-Luminous Components.

Organic piezochromic materials that manifest pressure-stimuli-responses are important in various fields such as data storage and anticounterfeiting. The manipulation of piezofluorochromic behaviors for these materials is promising but remains a great challenge. Herein, a non-luminous components regulated strategy is developed and organic molecular cages (OMCs), a burgeoning class of crystalline organic materials with structural dynamics, are first explored for the design of piezofluorochromic materials with tunable luminescence.

community transcriptomics illuminates CO-fixation potentials and supporting roles of phagotrophy and proton pump in plankton in a subtropical marginal sea.

Lineage-wise physiological activities of plankton communities in the ocean are important but challenging to characterize. Here, we conducted whole-assemblage metatranscriptomic profiling at continental shelf and slope sites in the South China Sea to investigate carbon fixation potential in different lineages. expression, the proxy of Calvin carbon fixation (CCF) potential, was mainly contributed by Bacillariophyta, Chlorophyta, Cyanobacteria, and Haptophyta, which was differentially affected by environmental factors among lineages.

Glyphosate (Roundup) as phosphorus nutrient enhances carbon and nitrogen accumulation and up-regulates phosphorus metabolisms in the haptophyte Isochrysis galbana.

Inorganic phosphate limitation for phytoplankton may be intensified with water stratification by global warming, and with the increasing nitrogen: phosphorus (N:P) ratio in coastal zones resulting from continuous anthropogenic N overloading. Under these circumstances, phytoplankton's ability to use dissolved organic phosphorus (DOP) will give species a competitive advantage. In our previous study, we have shown that the haptophyte Isochrysis galbana can use glyphosate (Roundup) as a P nutrient source to support growth, but the mechanism of how remains unexplored.

A grazing-driven positive nutrient feedback loop and active sexual reproduction underpin widespread Noctiluca green tides.

The mixoplankton green Noctiluca scintillans (gNoctiluca) is known to form extensive green tides in tropical coastal ecosystems prone to eutrophication. In the Arabian Sea, their recent appearance and annual recurrence have upended an ecosystem that was once exclusively dominated by diatoms. Despite evidence of strong links to eutrophication, hypoxia and warming, the mechanisms underlying outbreaks of this mixoplanktonic dinoflagellate remain uncertain.

Active viral infection during blooms of a dinoflagellate indicates dinoflagellate-viral co-adaptation.

This study represents the first that investigates virus infection in dinoflagellate blooms. Our findings reveal highly similar viral assemblages that infected the bloom species and a co-adapted metabolic relationship between the host and the viruses in the blooms, which varied between the prolonged and the short-lived blooms of the same dinoflagellate species. These findings fill the gap in knowledge regarding the identity and behavior of viruses in a dinoflagellate bloom and shed light on what appears to be the complex mode of infection.

A comparative study reveals the relative importance of prokaryotic and eukaryotic proton pump rhodopsins in a subtropical marginal sea.

Proton-pump rhodopsin (PPR) in marine microbes can convert solar energy to bioavailable chemical energy. Whereas bacterial PPR has been extensively studied, counterparts in microeukaryotes are less explored, and the relative importance of the two groups is poorly understood. Here, we sequenced whole-assemblage metatranscriptomes and investigated the diversity and expression dynamics of PPR in microbial eukaryotes and prokaryotes at a continental shelf and a slope site in the northern South China Sea.

Correlation between thyroid function indices and urine iodine levels in patients with nodular goiter.

Objective: To retrospectively analyze the iodine nutritional status in patients with nodular goiter (NG) and investigate a possible association between urinary iodine levels and thyroid function indices.

Methods: A total of 173 patients diagnosed with nodular goiter in the Fourth Hospital of Hebei Medical University from January 2019 to May 2021 were selected as the NG group, and 172 healthy individuals without thyroid diseases were selected after a physical examination as a control group. The data of all the participants were retrospectively assessed to explore the association between urinary iodine levels and thyroid function indices.

Expression analysis of TRAF2‑ and NCK‑interacting protein kinase (TNIK) and phosphorylated TNIK in papillary thyroid carcinoma.

The aim of the present study was to evaluate the expression of TRAF2- and NCK-interacting kinase (TNIK) and the levels of the active form of TNIK, phosphorylated (p)-TNIK, in papillary thyroid carcinoma (PTC), and to identify and compare the levels of TNIK and p-TNIK among PTC, benign thyroid tumors and normal tissues. The levels of TNIK and p-TNIK were examined by reverse transcription-quantitative (RT-q)PCR and immunohistochemical analysis (IHC) in PTC, benign thyroid tumors and normal tissues, and their association with clinicopathological features was evaluated. First, analysis of the Gene Expression Profiling Interactive Analysis and The Cancer Genome Atlas datasets suggested that the mRNA expression of TNIK was markedly increased in PTC tissues compared with that in normal tissues.

Tailoring the high-brightness "warm" white light emission of two-dimensional perovskite crystals a pressure-inhibited nonradiative transition.

Efficient warm white light emission is an ideal characteristic of single-component materials for light-emitting applications. Although two-dimensional hybrid perovskites are promising candidates for light-emitting diodes, as they possess broadband self-trapped emission and outstanding stability, they rarely achieve a high photoluminescence quantum yield of warm white light emissions. Here, an unusual pressure-induced warm white emission enhancement phenomenon from 2.

Cycloaddition enabled mutational profiling of 5-vinyluridine in RNA.

We report the detection of 5-vinyluridine (5-VUrd) in RNA at single nucleotide resolution mutational profiling. Maleimide cycloadducts with 5-VUrd in RNA cause a stop in primer extension during reverse transcription, and the full-length cDNA product from reverse transcription contains misincorporation across the cycloadduct site.

Transcriptomic-Guided Phosphonate Utilization Analysis Unveils Evidence of Clathrin-Mediated Endocytosis and Phospholipid Synthesis in the Model Diatom, .

Phosphonates are important components of marine organic phosphorus, but their bioavailability and catabolism by eukaryotic phytoplankton remain enigmatic. Here, diatom Phaeodactylum tricornutum was used to investigate the bioavailability of phosphonates and describe the underlying molecular mechanism. The results showed that 2-aminoethylphosphonic acid (2-AEP) can be utilized as an alternative phosphorus source.

In the face of the rapid increase of carbon emissions, climate warming, and an epidemic situation, low-carbon economy is attracting growing attention. Using bibliometric analysis and machine learning methods, the paper conducts a systematic review in the low-carbon economy. Using the Web of Science Core Collection database, 1433 articles from 1990 to 2021 were selected for review.

An atlas of posttranslational modifications on RNA binding proteins.

RNA structure and function are intimately tied to RNA binding protein recognition and regulation. Posttranslational modifications are chemical modifications which can control protein biology. The role of PTMs in the regulation RBPs is not well understood, in part due to a lacking analysis of PTM deposition on RBPs.

Physiological and metabolic effects of glyphosate as the sole P source on a cosmopolitan phytoplankter and biogeochemical implications.

Nutrient conditions influence the physiology and stoichiometry of marine phytoplankton. While extensive studies have documented the effects of abundances and types of nutrients such as nitrogen (N) and phosphorus (P), the effect of phosphonates as a P source is less understood and underexplored. Here, with the cosmopolitan coccolithophorid Emiliania huxleyi as a model phytoplankter, we investigated the effect of the phosphonate type of herbicide glyphosate as the sole P source in comparison with the P-depleted and P-replete (with 36 μM dissolved inorganic phosphate [DIP]) cultures.

The 3D-structure-mediated growth of zero-dimensional CsSnX nanocrystals.

Innovations in approaches to synthesize high-quality lead perovskite nanocrystals have enabled the prosperous development of nanocrystal-based optoelectronic devices in recent years. However, the transfer of these approaches to tin perovskite nanocrystals, which are the most promising lead-free perovskite candidates, remains unsuccessful. Herein, based on a three-dimensional (3D)-structure-mediated approach, monodispersed and highly luminescent inorganic zero-dimensional (0D) tin perovskite nanocrystals (NCs) are synthesized.

FOXP4 promotes laryngeal squamous cell carcinoma progression through directly targeting LEF‑1.

Forkhead box (FOX) proteins are multifaceted transcription factors that have been shown to be involved in cell cycle progression, proliferation and metastasis. FOXP4, a member of the FOX family, has been implicated in diverse biological processes in tumor initiation and progression. However, the molecular mechanisms of FOXP4 in laryngeal squamous cell carcinoma (LSCC) remain unknown.

SPX-related genes regulate phosphorus homeostasis in the marine phytoplankton, Phaeodactylum tricornutum.

Phosphorus (P) is an essential nutrient for marine phytoplankton. Maintaining intracellular P homeostasis against environmental P variability is critical for phytoplankton, but how they achieve this is poorly understood. Here we identify a SPX gene and investigate its role in Phaeodactylum tricornutum.

Identification of novel regulators of dendrite arborization using cell type-specific RNA metabolic labeling.

Obtaining neuron transcriptomes is challenging; their complex morphology and interconnected microenvironments make it difficult to isolate neurons without potentially altering gene expression. Multidendritic sensory neurons (md neurons) of Drosophila larvae are commonly used to study peripheral nervous system biology, particularly dendrite arborization. We sought to test if EC-tagging, a biosynthetic RNA tagging and purification method that avoids the caveats of physical isolation, would enable discovery of novel regulators of md neuron dendrite arborization.

Chromatin remodeling protein HELLS is critical for retinoblastoma tumor initiation and progression.

Retinoblastoma is an aggressive childhood cancer of the developing retina that initiates by biallelic RB1 gene inactivation. Tumor progression in retinoblastoma is driven by epigenetics, as retinoblastoma genomes are stable, but the mechanism(s) that drive these epigenetic changes remain unknown. Lymphoid-specific helicase (HELLS) protein is an epigenetic modifier directly regulated by the RB/E2F pathway.
