Analysis on agricultural carbon emissions transfer of inter-provincial trade in China.

The "carbon peaking and carbon neutrality goals" has put forward new requirements for China's agricultural carbon emission reduction. It is easy to ignore the carbon emission transfer caused by agricultural trade if the reduction responsibility of carbon emission is merely defined from the supply side. Therefore, it is necessary to conduct in-depth research on agricultural carbon transfer for reasonably dividing the responsibility of agricultural carbon reduction in different provinces.

Genomic survey and evolution analysis of calcium-dependent protein kinases in plants and their stress-responsive patterns in populus.

Background: Calcium-dependent protein kinases (CDPKs) phosphorylate downstream target proteins in response to signals transmitted by free calcium ions (Ca, one of the second messengers) and thus play important regulatory roles in many biological processes, such as plant growth, development, and stress response.

Results: A bioinformatic analysis, as well as thorough evolutionary and expression investigations, were conducted to confirm previous reports of functional evidence for plant CDPKs. Using the Phytozome database's BLAST search engine and the HMM search tool in TBtools software, we discovered that CDPKs are well conserved from green algae to flowering angiosperms in various gene family sizes.

Prediction and pathway models for assessing soil properties influencing soil selenium enrichment and bioavailability in Aksu Prefecture, northwest China.

Selenium (Se) in soil is the primary source of human Se intake, and its content and bioavailability are influenced by soil physicochemical properties. However, the influence of soil physicochemical properties on Se enrichment and bioavailability in soil remains uncertain. Therefore, this study investigated 536 soil samples and their corresponding wheat grain samples collected from the oasis zone of Aksu Prefecture, located in northwest China.

Codon Usage Pattern and its Influencing Factors for Mitochondrial CO Genes Among Different Subfamilies of Cerambycidae.

This study examined nucleotide composition and codon usage of mitochondrial CO (cytochrome oxidase) genes from four subfamilies of Cerambycidae. Nucleotide composition analysis of the CO genes revealed an AT-rich pattern in the four subfamilies of Cerambycidae. Furthermore, by analyzing the correlation between the overall nucleotide composition of CO genes and the nucleotide composition of the 3rd codon, we found that mutation pressure and natural selection were the key factors affected the CUB.

Intraspecific Variability of Xylem Hydraulic Traits of Growing in the Desert of Northern Xinjiang, China.

Plant hydraulic traits are essential for understanding and predicting plant drought resistance. Investigations into the mechanisms of the xylem anatomical traits of desert shrubs in response to climate can help us to understand plant survival strategies in extreme environments. This study examined the xylem anatomical traits and related functional traits of the branches of seven populations along a precipitation gradient, to explore their adaptive responses to climatic factors.

Weakening of global terrestrial carbon sequestration capacity under increasing intensity of warm extremes.

The net ecosystem exchange (NEE), determining terrestrial carbon sequestration capacity, is strongly controlled by climate change and has exhibited substantial year-to-year fluctuations. How the increased frequency and intensity of warm extremes affect NEE variations remains unclear. Here, we combined multiple NEE datasets from atmospheric CO inversions, Earth system models, eddy-covariance data-driven methods and climate datasets to show that the terrestrial carbon sequestration capacity is weakened during warm extreme occurrences over the past 40 years, primarily contributed by tropical regions (81% ± 48%).

Tree-ring maximum latewood density reveals unprecedented warming and long-term summer temperature in the upper Indus Basin, northern Pakistan.

Understanding long-term temperature variability in the Upper Indus Basin (UIB), northern Pakistan, and its driving mechanisms is challenging due to the scarcity of long observational records and available literature. In this study, we reconstructed a 651-year (1370-2020 CE) warm-season (March-September) temperature record using the tree-ring maximum latewood density (MXD) of blue pine (Pinus wallichiana). The reconstruction explains 57 % of the variance in actual temperature during the common calibration period (1972-2020 CE).

Modeling the temporal evolution of plastic film microplastics in soil using a backpropagation neural network.

Plastic films are a crucial aspect of agricultural production in China, as well as a key source of microplastics in farmland. However, research into the environmental behavior of microplastics derived from polyethylene (PE) and biodegradable plastic films such as polybutylene adipate-co-terephthalate (PBAT) is limited by inadequate knowledge of their evolution and fate in soil. Therefore, we conducted controlled soil incubation experiments using new and aged microplastics derived from prepared PE and PBAT plastic films to determine their temporal evolution characteristics in soil.

Impact of plant monoterpenes on insect pest management and insect-associated microbes.

The fight against insect pests primarily relies on the utilization of synthetic insecticides. However, improper application of these chemicals can lead to detrimental effects on both the environment and human health, as well as foster the development of insect resistance. Consequently, novel strategies must be implemented to address the challenges stemming from the prolonged use of synthetic insecticides in agricultural and public health environments.

Greater moisture impacts on radial growth of Larix sibirica in the eastern Altay Mountains since the 1990s.

Against the background of climate warming and humidification, the so-called 'divergence problem' reduces the stability of tree rings in response to climate, and affects the reliability of tree-ring reconstruction. Investigation of the divergence problem is crucial to improve our understanding of the response patterns of trees to climate warming, and provide a scientific basis for accurate climate reconstruction. Based on tree-ring width data for Siberian larch (Larix sibirica Ledeb.
