Abstract Heterotrimeric G proteins have been shown to transmit ultraviolet B (UV-B) signals in mammalian cells, but whether they also UV-B plant cells is not clear. In this paper, we report that 0.5 W m−2 induces stomatal closure Arabidopsis (Arabidopsis thaliana) by eliciting a cascade of intracellular signaling events including Gα protein, hydrogen peroxide (H2O2), and nitric oxide (NO). triggered significant increase H2O2 or NO levels associated with the wild type, these effects were...
Heterotrimeric G proteins function as key players in hydrogen peroxide (H2O2) production plant cells, but whether mediate ethylene-induced H2O2 and stomatal closure are not clear. Here, evidences provided to show the Gα subunit GPA1 a missing link between ethylene guard cell signalling. In wild-type leaves, ethylene-triggered synthesis were dependent on activation of Gα. mutants showed defect closure, whereas wGα cGα overexpression lines faster response ethylene. Ethylene-triggered...
Allocation of limiting resources, such as nutrients, is an important adaptation strategy for plants. Plants may allocate different nutrients within a specific organ or the same nutrient among organs. In this study, we investigated allocation strategies nitrogen (N) and phosphorus (P) in leaves, stems roots 126 shrub species from 172 shrubland communities Northern China using scaling analyses. Results showed that N P have relationships plant The concentration across organs tended to be...
Abstract: The walnut (Juglans regia) is a woody oilseed crop with high economic and food value as its kernels are edible hulls can be widely used in oil extraction plugging, chemical raw materials, water purification. Currently, red varieties have emerged, attracting consumer interest due to their nutritional values they rich anthocyanins. WD40 widespread superfamily eukaryotes that play roles plant color regulation resistance stresses. In order screen for JrWD40 associated color, we...
Abstract Idiopathic pulmonary fibrosis (IPF) is a kind of interstitial lung disease (ILD). It has high incidence rate and mortality. Its pathogenesis remains unclear. So far, no effective methods have been found for the early diagnosis IPF. Ferroptosis reported to be critical in initiation progression Therefore, our aim was identify hub gene related ferroptosis co-expressed peripheral blood tissue patients with Sequencing data were obtained from Gene Expression Omnibus database. A...
Abstract Community assembly processes is the primary focus of community ecology. Using phylogenetic‐based and functional trait‐based methods jointly to explore these along environmental gradients are useful ways explain change mechanisms under changing world. Our study combined test in wide range elevation other habitat factors. We collected our data at 40 plots Taibai Mountain, China, with more than 2,300 m altitude difference area then measured traits Variance partitioning was used...
Abstract Quantifying the drivers underlying distribution of biodiversity during succession is a critical issue in ecology and conservation also can provide insights into mechanisms community assembly. Ninety plots were established Loess Plateau region northern Shaanxi China. The taxonomic phylogenetic (alpha beta) diversity quantified within six stages. Null models used to test whether distance observed differed from random expectations. Taxonomic beta did not show regular pattern, while...
Abstract. Concentrations of leaf nitrogen (N) and phosphorus (P) are two key traits plants for ecosystem functioning dynamics. Foliar stoichiometry varies remarkably among life forms. However, previous studies have focused on the stoichiometric patterns trees grasses, leaving a significant knowledge gap shrubs. In this study, we explored intraspecific interspecific variations N P concentrations in response to changes climate, soil property, evolutionary history. We analysed 1486 samples...
In the context of secondary forest succession, abovegroundbelowground interactions are known to affect dynamics and functional structure plant communities. However, links between soil microbial communities, abiotic properties, traits in case semi-arid arid ecosystems unclear. this study, we investigated changes species diversity community composition corresponding effects properties during a ≥150-year succession on Loess Plateau, which represents typical ecosystem China. Plant fragments...
Soil microorganisms are critical biological indicators for evaluating soil health and play a vital role in carbon (C)-climate feedback. In recent years, the accuracy of models terms predicting C pools has been improved by considering involvement microbes decomposition process ecosystem models, but parameter values these have assumed researchers without combining observed data with calibrating microbial models. Here, we conducted an observational experiment from April 2021 to July 2022...
Walnut (Juglans) species are used as nut crops worldwide. Eastern black walnut (EBW, Juglans nigra), a diploid, horticultural important woody is native to much of eastern North America. Although it highly valued for its wood and nut, there few resources understanding EBW genetics. Here, we present high-quality genome assembly J. nigra based on Illumina, Pacbio, Hi-C technologies. The size was 540.8 Mb, with scaffold N50 35.1 99.0% the anchored 16 chromosomes. Using this reference,...
Abstract Questions Are leaf traits related to plant growth efficiency different in stages of forest succession on the L oess P lateau northern S haanxi, C hina? How do ecological strategies change with progress succession? Can a combination some key across species discriminate successional stages? Location Loess Plateau region Shaanxi, China. Methods A set 31 plots was established study area. Twenty‐two were measured dominant representative six stages: three pertaining morphology, nine...
Abstract Manchurian walnut ( Juglans mandshurica Maxim.) is a synonym of J . cathayensis , diploid, vulnerable, temperate deciduous tree valued for its wood and nut. It also as rootstock regia because reported tolerance lesion nematode. Reference genomes are available several species, our goal was to produce de novo, chromosome‐level assembly the genome. Here, we an improved with contig N50 size 6.49 Mb scaffold 36.1 Mb. The total genome 548 encoding 29,032 protein coding genes which were...
Covering about 30% of the global total land area, desert ecosystems have been influenced by warming and nitrogen deposition. However, it remains unclear how respond to Therefore, we conducted a greenhouse experiment examine impacts N addition on plant–soil system Neotrinia splendens, dominant plant in ecosystem Northern China. Our findings revealed that low-N dose (N1) high-N additions (N2) increased biomass 22.83% 54.23%, respectively; meanwhile, moderate (T2) severe (T3) decreased 39.07%...
Abstract: The seed embryos of Isatis indigotica Fort were exposed to He-Ne laser (5.23 mW/mm2, radiated for 5 min) and microwave (1.26 8 s) irradiation determine the effects pretreatment on enzyme activities, biophoton emission cotyledon. Then: (i) changes in activities enzymes I. cotyledon (such as amylase, transaminase, proteinase) measured investigate pretreatment; (ii) was speed cell division metabolism. Results from these experiments indicated that: proteinase pretreated by...
Stomata control the water loss for transpiration and CO2 uptake photosynthesis. However, relationships between photosynthesis stomatal traits across a wide range of species are largely been unknown. Here, we tested among maximum photosynthetic rate (Amax), density (SD), length (SL) conductance to vapour (gmax) 45 woody plants on Loess Plateau. We found correlations with Amax gmax were different. Specifically, was positively correlated SD. negatively SD SL, which inconsistent previous...
To determine the effect of CO(2) laser pretreatment wheat seeds on physiological tolerance seedlings to chilling stress, were exposed radiation for 300 s. After being cultivated 48 h at 25 degrees C, subjected stress 24 h. Selected and biochemical parameters measured in 6-day-old seedlings. We observed that enhanced concentrations malondialdehyde oxidized glutathione while decreasing activities nitric oxide synthase, catalase, peroxidase, superoxide dismutase leaves compared with controls....
