Ordered rise and disordered fall: dynamic changes of membrane lipids during girdling-induced tree mortality in Populus yunnanensis.

Understanding the mechanisms behind drought-induced tree mortality is crucial for predicting the impact of global climate change on forests. We studied the mechanism at the cellular level in Populus yunnanensis by profiling membrane lipid molecules in leaves, branch phloem, top and bottom trunk phloem under trunk-girdling-induced drought conditions. We found that both lipid composition and content changed, depending on the tree's tissue positions and the progression of the girdling effect.

Remodeling of membrane lipids associated with ABA-induced desiccation tolerance in Physcomitrium patens.

Pretreatment of Physcomitrium patens with abscisic acid (ABA) has been shown to induce desiccation tolerance. While previous research suggests that ABA-induced production of proteins and soluble sugars contributes to desiccation stress tolerance, additional mechanisms underlying this tolerance remain unclear. In this study, we found that ABA pretreatment led to increased levels of digalactosyl diacylglycerol (DGDG), phosphatidylcholine (PC), and phosphatidylinositol (PI), along with a decrease in monogalactosyl diacylglycerol (MGDG).

Cadmium and calcium ions' effects on the growth of Pleurotus ostreatus mycelia are related to phosphatidylethanolamine content.

Heavy metal Cd can easily be accumulated by fungi, causing significant stress, with the fungal cell membrane being one of the primary targets. However, the understanding of the mechanisms behind this stress remains limited. This study investigated the changes in membrane lipid molecules of Pleurotus ostreatus mycelia under Cd stress and the antagonistic effect of Ca on this stress.

Association between vitamin B1 intake and hyperuricemia in adults.

Studies investigating the relationship between dietary vitamin B1 intake and risk of Hyperuricemia (HU) are scarce, the present study aimed to examine the association of dietary vitamin B1 intake and HU among adults. This cross-sectional study included 5750 adults whose data derived from National Health and Nutrition Examination Survey (NHANES) from March 2017 to March 2020. The dietary intake of vitamin B1 was assessed using 24-h dietary recall interviews.

Microvascular abnormalities induced by hand-transmitted vibration reflects in finger systolic blood pressure: a cross-sectional study in China.

Finger SBP (FSBP) measurement is a potential way of assessing vascular components. This study aims to comprehensively investigate the relationship between the occurrence of the vibration-induced white finger (VWF) and changes in FSBP and then set the application value of FSBP measurements in the early diagnosis of VWF.

Clonal Propagation and Assessment of Biomass Production and Saponin Content of Elite Accessions of Wild var. .

Vinculin Identified as a Potential Biomarker in Hand-Arm Vibration Syndrome Based on iTRAQ and LC-MS/MS-Based Proteomic Analysis.

Local vibration can induce vascular injuries, one example is the hand-arm vibration syndrome (HAVS) caused by hand-transmitted vibration (HTV). Little is known about the molecular mechanism of HAVS-induced vascular injuries. Herein, the iTRAQ (isobaric tags for relative and absolute quantitation) followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) proteomics approach was applied to conduct the quantitative proteomic analysis of plasma from specimens with HTV exposure or HAVS diagnosis.

Optimization of Submerged Culture Parameters of the Aphid Pathogenic Fungus Based on Sporulation and Mycelial Biomass.

(JMF-01), as an entomopathogenic fungus, can effectively control agricultural pests and has the potential to be a biocontrol agent. To promote mycelial growth and sporulation, we investigated the optimal submerged culture conditions for . In this study, we used the single-factor method and Box-Behnken design and determined the virulence of the submerged culture against after optimization.

First report of leaf blight caused by on wheat in China.

Wheat ( L.) is the main grain crop in Ningxia Hui Autonomous Region, China. A new leaf blight disease of wheat was observed in many wheat fields in Yinchuan City and Wuzhong City of Ningxia during 2020-2021.

Establishing Tetraploid Embryogenic Cell Lines of to Facilitate Tetraploid Plantlet Production and Phenotyping.

The production of synthetic polyploids for plant breeding is compromised by high levels of mixoploids and low numbers of solid polyploid regenerants during induction. Somatic embryogenesis could potentially contribute to the maximization of solid polyploid production due to the single cell origin of regenerants. In the present study, a novel procedure for establishing homogeneous tetraploid embryogenic cell lines in has been established.

The Overexpression of Promotes Development and Increases Resistance to Nitrogen Deficiency in .

NUTCRACKER (NUC) is a transcription factor expressed in multiple tissues, but little is known about its physiological roles. In this study, we explored the physiological function of with the knockout, rescue, and overexpression lines. We found that overexpression promoted development at the germination, seedling, and juvenile stages.

Comprehensive analysis of the Ppatg3 mutant reveals that autophagy plays important roles in gametophore senescence in Physcomitrella patens.

Background: Autophagy is an evolutionarily conserved system for the degradation of intracellular components in eukaryotic organisms. Autophagy plays essential roles in preventing premature senescence and extending the longevity of vascular plants. However, the mechanisms and physiological roles of autophagy in preventing senescence in basal land plants are still obscure.

The Serine Carboxypeptidase-Like Gene Negatively Regulates Membrane Lipid Metabolism in .

The has 51 proteins annotated as serine carboxypeptidase-like (SCPL) enzymes. Although biochemical and cellular characterization indicates SCPLs involved in protein turnover or processing, little is known about their roles in plant metabolism. In this study, we identified an mutant, (), that was insensitive to the inhibitory effect of 1-butanol on seed germination.

Genome-Wide Analysis of the MYB Transcription Factor Superfamily in .

MYB transcription factors (TFs) are one of the largest TF families in plants to regulate numerous biological processes. However, our knowledge of the MYB family in is limited. We identified 116 MYB genes in the genome, which were classified into the R2R3-MYB, R1R2R3-MYB, 4R-MYB, and MYB-related subfamilies.

Establishment of a fluorescent PCR melting curve method for detecting asthma susceptibility using gene SNP typing.

To develop a detection method for single nucleotide polymorphisms (SNPs) of bronchial asthma (BA) susceptibility genes (, and ) based on fluorescence PCR melting curves. Peripheral blood samples from 33 patients with BA were collected. DNA was extracted, and positive plasmids were constructed.

Phospholipase D antagonist 1-butanol inhibited the mobilization of triacylglycerol during seed germination in .

Storage oil breakdown plays an important role in the life cycle of many plants by providing the carbon skeletons that support seedling growth immediately following germination. 1-Butanol, a specific inhibitor of phospholipase D (PLD)-dependent production of the signalling molecule phosphatidic acid (PA), inhibited seed germination. N-Acylethanolamines (NAEs), which have been shown to inhibits PLDα1 activity, have no effect on seed germination.

A20 regulates canonical wnt-signaling through an interaction with RIPK4.

A20 is a ubiquitin-editing enzyme that is known to regulate inflammatory signaling and cell death. However, A20 mutations are also frequently found in multiple malignancies suggesting a potential role as a tumor suppressor as well. We recently described a novel role for A20 in regulating the wnt-beta-catenin signaling pathway and suppressing colonic tumor development in mice.
