Unveiling the impact of biodegradable polylactic acid microplastics on meadow soil health.

Soil microplastics (MPs) pollution has garnered considerable attention in recent years. The use of biodegradable plastics for mulching has led to significant quantities of plastic entering agro-ecosystems. However, the effects of biodegradable polylactic acid (PLA) plastics on meadow soils remain underexplored.

Spatio-temporal analysis of litterfall load in the lower reaches of Qarqan and Tarim rivers using BP neural networks.

Litterfall load is crucial in maintaining ecosystem health, controlling wildfires, and estimating carbon stock in arid regions. However, there is a lack of spatiotemporal analysis of litterfall in arid riparian forests. This study aims to estimate Litterfall load using a BP neural network based on vegetation indices from Landsat 5 and 8 satellite images, litterfall inventory data, slope, and distance to major river tributaries.

Assessment and Prediction of the Food Production Capacity and Consumption Gap in Arid Oasis Metropolitan Area.

Food security is the foundation of sustainable human development, and the balance between food supply and demand in urban areas is highly important for promoting residents' health and the sustainable development of cities. This paper takes the Urumqi Metropolitan Area (UMA), a typical oasis urban area, as the study area and uses the food production-demand gap indicator to assess the balance of food production and consumption in the region from 2000 to 2020 and projects food demand in 2030-2060. The results show, first, that residents' food consumption is characterized by high carbohydrate, protein, and fat consumption, and that this put more pressure on food production.

Recent achievements in noble metal-based oxide electrocatalysts for water splitting.

The search for sustainable energy sources has accelerated the exploration of water decomposition as a clean H production method. Among the methods proposed, H production water electrolysis has garnered considerable attention. However, the process of H production from water electrolysis is severely limited by the slow kinetics of the anodic oxygen evolution reaction and large intrinsic overpotentials at the anode; therefore, suitable catalysts need to be found to accelerate the reaction rate.

Beyond the desert sands: decoding the relationship between camels, gut microbiota, and antibiotic resistance through metagenomics.

Background: Camels, known as the enduring "ships of the desert," host a complex gut microbiota that plays a crucial role in their survival in extreme environments. However, amidst the fascinating discoveries about the camel gut microbiota, concerns about antibiotic resistance have emerged as a significant global challenge affecting both human and animal populations. Indeed, the continued use of antibiotics in veterinary medicine has led to the widespread emergence of antibiotic-resistant bacteria, which has worsened through gene transfer.

The P-type ATPase gene AHA5 is involved in proanthocyanidins accumulation in Medicago truncatula.

Proanthocyanidins (PAs) are the second most abundant plant phenolic natural products. The proton membrane H-ATPase (AHA) is required for PA transportation in vacuoles, but it remains unclear which AHA gene(s) encode tonoplast proton pump in M. truncatula.

Differential insights into the distribution characteristics of bacterial communities and their response to typical pollutants in the sediment and soil of large drinking water reservoir.

In this study, a large drinking water reservoir (Fengshuba Reservoir) was chosen as a representative case, and the bacterial communities in the sediments and soils of Water-level fluctuating zone (WLFZ) as well as their responses to heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) were systematically investigated. The results indicated that the abundance and diversity of the bacterial community obviously changed with seasonal hydrological variations in sediments, and the absolute abundance and composition of bacteria community differed significantly between the sediment phase and soil phase. Bacteria with the ability to degrade pollutants rapidly proliferate and gain ascendancy in the soil phase, with Burkholderia-Caballeronia-Paraburkholderia (B-C-P) and Bradyrhizobium forming the core of the largest community.

A global analysis of plant nutrient limitation affected by atmospheric nitrogen and phosphorous deposition.

Uncovering the response of plant functional types (PFTs) to nutrient limitation caused by atmospheric deposition is critical for assessing the health of terrestrial ecosystems under climate change conditions. However, it remains unclear how atmospheric deposition and underlying ecological factors affect PFTs globally. To address this, we compiled a global dataset of four PFTs, i.

Antifungal peptides from living organisms.

In the post-COVID-19 era, people are increasingly concerned about microbial infections, including fungal infections that have risen in recent years. However, the currently available antifungal agents are rather limited. Worse still, the widespread use of the antifungal agents has caused the emergence of antifungal resistance in , , and species.

Root system architecture plasticity with beneficial rhizosphere microbes: Current findings and future perspectives.

The rhizosphere microbiota, often referred to as the plant's "second genome" plays a critical role in modulating root system architecture (RSA). Despite this, existing methods to analyze root phenotypes in the context of root-microbe interactions remain limited, and the precise mechanisms affecting RSA by microbes are still not fully understood. This review comprehensively evaluates current root phenotyping techniques relevant to plant-microbe interactions, discusses their limitations, and explores future directions for integrating advanced technologies to elucidate microbial roles in altering RSA.

ScDREBA5 Enhances Cold Tolerance by Regulating Photosynthetic and Antioxidant Genes in the Desert Moss Syntrichia caninervis.

Extreme cold events, becoming more frequent, affect plant growth and development. Much is known about C-repeat binding transcription factor (CBF)-dependent cold-signaling pathways in plants. However, the CBF-independent regulatory pathway in angiosperms is unclear, and the cold-signaling pathways in non-angiosperms lacking CBFs, such as the extremely cold-tolerant desert moss Syntrichia caninervis, are largely unknown.

Spatiotemporal differences induced changes in the structure and function of the gut microbiota in an endangered ungulate.

The composition and function of animal gut microbiota are shaped by various factors, among which diet is one of the major factors. Diet is affected by seasonal shifts and geographical differences, which in turn impact the host's nutritional levels. To adapt to these environmental changes, the gut microbiome often produces matching responses.

Prediction and mapping of leaf water content in Populus alba var. pyramidalis using hyperspectral imagery.

Leaf water content (LWC) encapsulates critical aspects of tree physiology and is considered a proxy for assessing tree drought stress and the risk of forest decline; however, its measurement relies on destructive sampling and is thus less efficient. Advancements in hyperspectral imaging technology present new prospects for noninvasively evaluating LWC and mapping drought severity across forested regions. In this study, leaf samples were obtained from Populus alba var.

Adaptation of High-Altitude Plants to Harsh Environments: Application of Phenotypic-Variation-Related Methods and Multi-Omics Techniques.

High-altitude plants face extreme environments such as low temperature, low oxygen, low nutrient levels, and strong ultraviolet radiation, causing them to adopt complex adaptation mechanisms. Phenotypic variation is the core manifestation of ecological adaptation and evolution. Many plants have developed a series of adaptive strategies through long-term natural selection and evolution, enabling them to survive and reproduce under such harsh conditions.
