2025-04-23Bellidifolin from Swertia diluta Improves High-Fat Diet-Induced Obesity via Gut Microbiota and Bile Acid RegulationBellidifolin (BEL) isolated from Swertia diluta has been demonstrated significant efficacy in mitigating high-fat diet-induced obesity and dyslipidemia in a mice model. This effect is mediated through modulation of gut microbiota composition and enhancement of bile acid biosynthesis and excretion, resulting in improved lipid metabolic profiles. Obesity and related metabolic disorders, including hyperlipidemia and non-alcoholic fatty liver disease, have become significant global public health challenges. According to the World Health Organization, the worldwide obesity rate has nearly tripled since 1975, affecting approximately 650 million adults. High-fat diet (HFD) is a key driver of ...Read More -
2025-04-23Recent Advances in Pan-genome Analysis of Forest TreesPan-genome data have been utilized to explore the genetic basis of adaptation, but such studies remain limited in forest trees. Here, the authors constructed the first pan-genome of Quercus variabilis and demonstrated how introgression facilitates local adaptation in oak species. Understanding the genetic basis of local adaptation is a crucial question in evolutionary biology. Previous studies, relying on single reference genomes and short-read sequencing, have struggled to comprehensively resolve structural variants (SVs) — large-scale genomic alterations proven to regulate stress-response genes and drive phenotypic di...Read More -
2025-04-23From Rhizosphere to Resorption: Comparing Phosphorus Adaptation in Trees and Herbs Under Decadal Acid Rain StressA 12-year acid rain simulation study shows tropical trees maintain stable phosphorus (P) despite declining soil inorganic P, while herbs decline leaf P and fresh litter P due to reduced soil inorganic and organic soil P. Tree rhizosphere P fraction is linked to soil physicochemical properties, whereas herbs rely on microbial-driven organic P min... As global soil acidification intensifies, tropical and subtropical forests face growing phosphorus (P) limitations, raising questions about which functional group—trees or herbs—would be disproportionately affected. To address this, researchers from the South China Botanical Garden, Chinese Academy of Sciences, conducted a long-term acid rain ...Read More -

2025-04-17200,000-Year Dune Chronosequence Reveals Synergistic Regulation of Climate and Pedogenesis on Soil Organic Matter TransformationSelected two coastal dune chronosequences spanning 2 million years—Jurien Bay in a hot, arid climate and Warren in a wet, cold climate (Figure 1)—to systematically analyze the influence of climate and pedog Against the backdrop of intensifying global climate change, a deeper understanding of soil carbon sequestration mechanisms is crucial for enhancing the carbon sink function and stability of terrestrial ecosystems. Dissolved organic matter (DOM) and glomalin-related soil protein (GRSP), as key components of the soil carbon pool, play pivotal role...Read More -
