2025-10-28Unraveling the Mechanism of Heavy Metal Biomineralization by Indigenous BacteriaHeavy metal contamination is a critical environmental threat requiring sustainable remediation solutions. This study demonstrates the high efficacy of microbial-induced carbonate precipitation (MICP) using Bacillus strains to immobilize cadmium (Cd) and lead (Pb) in aqueous systems. While both metals were removed at high efficiencies (>98%) in s... With the continuous expansion of industrialization and agricultural activities, contamination of water bodies and soils by heavy metals such as cadmium (Cd) and lead (Pb) has evolved into a severe global environmental challenge. These toxic metals are not only persistent in the environment and highly bio-toxic, but also readily bioaccumulate thr...Read More -
2025-10-11Subtropical Forests Soils May Continue to Store Carbon Under Moderate WarmingClimate warming increases both above- and below-ground temperatures, altering plant-soil interactions and reshaping soil organic carbon dynamics. This study found that some subtropical forests could continue to accumulate SOC under future moderate warming, albeit with distinct accumulation patterns of different SOC fractions across soil layers. ... A long-term field experiment has revealed that humid subtropical forests may continue to accumulate soil carbon under moderate warming, challenging the long-held assumption that global warming inevitably turns these ecosystems into carbon sources. This finding has been published in One Earth on October 6, 2025.Led by Prof. LIU Juxiu from the Sou...Read More -
2025-10-11Genomic Diversity Decodes Evolutionary Mystery of "Living Fossil" Tree FernsThe evolutionary mechanisms enabling the "living fossils" Cyatheaceae tree ferns, with conserved morphology since the Jurassic, to exhibit high resilience and diversity remain unclear. Our study reveals that an ancient whole-genome duplication event provided the genetic basis for their adaptation and diversification, while ongoing genomic plasti... Cyatheaceae tree ferns represent a typical ancient relict group within pteridophytes, drawing significant attention due to their archaic origins and distinctive tree-like forms. Their macroscopic morphology has remained highly conserved since the Jurassic period, earning them the reputation as "living fossils" from the age of dinosaurs. Despite ...Read More -
2025-09-26Nuclear factor-Y transcription factors in crops: Biological roles, regulation, and breeding applicationsNF-Y transcription factors play a pivotal role in regulating growth, development, and stress responses in crops. This review comprehensively summarizes current understanding of crop NF-Y functions across diverse regulatory layers, establishing a theoretical basis for their application in molecular breeding, and further addressing the practical s... A research team from the Restoration Ecology Group of the South China Botanical Garden, Chinese Academy of Sciences reviewed the biological functions, regulatory mechanisms and breeding applications of NF-Y transcription factors in crops.This review provide a systematic summary of the current knowledge of NF-Y in crops across multiple regulatory...Read More -
2025-09-26Greenspace exposure and its dual role as mediator and moderator in the relationship between urban density and mental healthUrban green space visitation and availability jointly buffer the mental health risks of high-density living. Community gardens and municipal parks provide the strongest and most consistent protective effects. Mental health has become a pressing global challenge, accounting for 32% of the global burden of life-threatening diseases. The COVID-19 pandemic further intensified this crisis, with a 25% increase in the prevalence of anxiety and depression worldwide. Urban residents are particularly vulnerable, facing risks associated with environmental pollu...Read More -

2025-09-16Reveals divergent phosphorus adaptation strategies of tropical tree-mycorrhizal types after 12 years of simulated acid rainIntensifying acid rain is expected to exacerbate soil phosphorus (P) deficiency and reduce plant productivity in tropical forests. From the perspectives of both soil P acquisition and foliar P utilization, this study found the divergent strategies of tropical mycorrhizal trees to cope with acid-induced P deficiency. Acid rain is one of the most serious global environmental problems. Especially in southern China, persistent acid rain has led to severe soil acidification and the depletion of nutrients and base cations, thereby threatening ecosystem structure and function. Previous studies of Qi Deng's lab have shown that soil acidification after decades acid ...Read More -
2025-09-16Tree-mycorrhizal types differ in their biomass response to nitrogen additionTree symbiotic associations with different mycorrhizal fungi (arbuscular mycorrhizal [AM] vs. ectomycorrhizal [ECM]) are a key predictor of woody biomass carbon (C) gain in response to nitrogen (N) addition.Therefore, shifts in the relative abundance of AM versus ECM trees could be a critical determinant of the future forest C sink under continu... A new study reveals that tree symbiotic associations with different mycorrhizal fungi (arbuscular mycorrhizal [AM] vs. ectomycorrhizal [ECM]) are a key predictor of woody biomass carbon (C) gain in response to nitrogen (N) addition. The study was published in Soil Biology and Biochemistry in 2025.From the South China Botanical Garden of the Chin...Read More
