Wheat (Triticum aestivum) is a staple food crop providing essential nutrition to global population. However, water scarcity and increasing drought stress, because of climate change, threaten its productivity. Oxidative stress increases the production of reactive oxygen species (ROS) due to drought which damages the plant cellular metabolism.

Guangxi Key Laboratory of Plant Conservation and Restoration Ecology in Karst Terrain, Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and Chinese Academy of Sciences, Guilin 541006, China.

Priority effects-the phenomenon where early-arriving species influence the establishment, growth, and reproduction of later-arriving species during community assembly-play a critical role in determining the invasion success of exotic species. However, how priority effects are influenced by nitrogen (N) availability remains understudied. The invasive species has rapidly expanded its range in China over the past few years.

Tannery solid waste poses significant environmental challenges owing to its high metal content, especially Cr. Converting this waste into value-added byproduct biochar offers a sustainable management approach to reducing the waste load on landfill sites and also guarding the nearby fauna, flora and water bodies. This study aimed to develop metal-resistant microbial consortium loaded biochar (MCLB) by inoculating tannery solid waste biochar (BC) with consortium of ten and/or five strains and their effect was evaluated on the morphological and biochemical attributes of sunflowers including metals immobilization.

Land availability and policy commitments limit global climate mitigation from forestation.

Science

August 2025

School of Atmospheric Sciences, Key Laboratory of Tropical Atmosphere-Ocean System (Ministry of Education), Guangdong Province Key Laboratory for Climate Change and Natural Disaster Studies, Sun Yat-sen University, Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai, China.

Forestation (afforestation and reforestation) could mitigate climate change by sequestering carbon within biomass and soils. However, global mitigation from forestation remains uncertain owing to varying estimates of carbon sequestration rates (notably in soil) and land availability. In this study, we developed global maps of soil carbon change that reveal carbon gains and losses with forestation, primarily in the topsoil.

Pu-erh tea polyphenol aggregates (PTPAs), macromolecular complexes analogous to theabrownin formed during microbial fermentation, are key bioactive components in this tea. Although their bioactivities are documented, critical gaps persist regarding both precise structural features and molecular mechanisms underlying the anti-inflammatory efficacy across biological models. To address these limitations, we systematically analyzed PTPAs using integrated methods, including alkaline hydrolysis, acid hydrolysis, and benzyl mercaptan-mediated degradation.

We face increasing concerns about how the local diversity of native plant communities responds to various drivers of global change, yet often lack comprehensive studies that integrate several components of diversity and the effects of both local and regional drivers of change. We analyzed changes in taxonomic, functional, and phylogenetic diversity across 2681 (semi-)permanent temperate forest understory plots surveyed and resurveyed for all vascular plants over intervals of 15-78 yr, spanning 72 regions distributed across Europe. We quantified temporal changes in these diversity indices and assessed their responses to changes in both local drivers (plot-level overstory cover, indicator values for soil nutrients) and regional shifts in macroclimate and nitrogen deposition.

Axenic cultures are essential for studying microbial ecology, evolution, and genomics. Despite the importance of pure cultures, public culture collections are biased towards fast-growing copiotrophs, while many abundant aquatic prokaryotes remain uncultured due to uncharacterized growth requirements and oligotrophic lifestyles. Here, we applied high-throughput dilution-to-extinction cultivation using defined media that mimic natural conditions to samples from 14 Central European lakes, yielding 627 axenic strains.

Understanding how weather conditions during early development influence reproductive success is essential for predicting avian responses to climate change. We used a 40-year dataset from a nest-box population of collared flycatchers (Ficedula albicollis) to examine how temperature and precipitation during the incubation and nestling periods affected three key components of reproductive performance: hatchling number, fledgling production, and local offspring recruitment. We found that higher ambient temperatures during the nestling period were associated with a decreased probability of brood failure and a higher number of recruits.

Single-dose infusion of engineered viral receptor binding domain confers rapid and durable protection against viral infection.

Commun Biol

August 2025

MOE Key Laboratory of Model Animal for Disease Study, Model Animal Research Center, Department of Oncology, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, 210061, China.

Developing both rapid- and long-acting antiviral drugs for single-dose administration can improve medication adherence and protect people at risk of infection. To provide proof of this concept, here, we designed multimerized form of viral receptor-binding domains (RBDs) to immediately occupy viral receptors to block infection and subsequently induce virus-specific protective immunity. We engineered SARS-CoV-2 RBD, enhancing its affinity to ACE2 and immunogenicity through multimerization and Fc modification.

Generation and Nutritional Evaluation of Intragenic Rice with α-Linolenic Acid Hyperfortified in Seeds.

J Agric Food Chem

August 2025

Key Laboratory of Plant Molecular Physiology, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P. R. China.

α-Linolenic acid (ALA) serves as a precursor of long-chain ω-3 fatty acids, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Humans cannot produce ALA due to a lack of ω-3 (Δ-15) fatty acid desaturase (FAD), which converts linoleic acid (LA) into ALA in plants. We developed ALA hyperfortified intragenic rice via a double T-DNA transformation strategy, with an expression cassette containing endogenous ω-3/Δ15 fatty acid desaturase () gene, endosperm-specific promoter, and terminator in one T-DNA, and the selectable marker gene in the other.

State Key Laboratory of Plant Diversity and Specialty Crops, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming, 650201, China.

The structural and ecological significance of ericoid mycorrhizal (ErM) fungi is well recognized. Yet, it remains unknown whether the coexistence of ericaceous plants is facilitated by their symbioses with ErM fungi. Here, we use Rhododendron (Ericaceae) as a model to investigate how phylogenetic and functional limiting similarity, or facilitation through ErM fungal metacommunity, influences their co-occurrence in mountain ecosystems.

The tree growth-herbivory relationship depends on functional traits across forest biodiversity experiments.

Nat Ecol Evol

August 2025

State Key Laboratory of Forage Breeding-by-Design and Utilization, Key Laboratory of Vegetation and Environmental Change, Institute of Botany, Chinese Academy of Sciences, Beijing, China.

While studies have demonstrated that higher tree species richness can increase forest productivity, the relationships between tree species richness, tree growth and herbivore damage remain insufficiently explored. Here we investigate these linkages using data from 8,790 trees across 80 species in 9 biodiversity experiments, spanning temperate and subtropical biomes. Despite considerable geographic variation, we reveal an overall positive relationship between tree species richness and insect herbivory, as well as between tree growth and herbivory, at individual, species and community levels.
