2025-12-18New Progress in the Molecular Mechanisms of HeterostylyResearch on the distylous Cordia subcordata provides insights into the convergent evolution of the hemizygous S-locus and establishes a link between style-length regulation via CsGA2ox6-mediated gibberellin deactivation and the potential control of self-incompatibility. Since Charles Darwin published The Different Forms of Flowers on Plants of the Same Species in 1877, heterostyly has served as a classic model system in studies of plant reproductive biology. Heterostyly is a floral polymorphism controlled by a S-locus supergene and is characterized by the presence of two (distyly) or three (tristyly) floral mor...Read More -
2025-12-18From field observations to laboratory simulations: Warming promotes manganese-phosphorus remobilization in estuarine sedimentsIn this work, the characteristic mechanisms of P remobilization in sediments of the Jiaomen Channel were explored using sequential extraction method, diffusive gradients in thinfilms (DGT) device, and pore-water sampler. The results showed that Intense organic matter mineralization removes dissolved Mn from pore water as carbonates, triggering a... Recently, Lei Gao’s research team from the South China Botanical Garden, Chinese Academy of Sciences, has published a research paper on Journal of Hydrology, exploring the dynamic mechanism of phosphorus (P) release from estuarine sediments response to warming. Combining field investigations and laboratory experiments, the study captured key ev...Read More -
2025-12-15How Microplastics Regulate Soil Carbon Storage via Mycorrhizal Fungi and GlomalinMicroplastics significantly enhance soil organic carbon storage by reshaping bacterial and arbuscular mycorrhizal fungal communities and promoting glomalin-related soil protein. Biodegradable microplastics inhibit the growth of Scaevola taccada, highlighting the dual ecological effects of biodegradable microplastics in sensitive island ecosystems. Microplastics, defined as plastic particles ≤ 5 mm in size, have emerged as a global environmental concern due to their widespread distribution and potential toxicity to ecosystems and human health. While research on microplastics has traditionally focused on marine environments, increasing evidence suggests that terrestrial ecosystems, particu...Read More -

2025-12-10Urbanization destabilizes soil organic carbon (SOC) in urban forests, threatening their long-term function as carbon sinksWe review how urbanization influences the stability of soil organic carbon (SOC) along an urban–rural forest gradients, and find that urban forest soils generally have lower SOC stability compared to suburban and rural forest soils. In urban forest, the dominant influencing factors of SOC stability are anthropogenic stressors, while the dominan... Urbanization disrupts SOC stability in forest ecosystems, weakening their vital role as carbon sinks. As cities expand and land-use intensifies, it becomes critical to understand how urban pressures disrupt the underlying mechanisms that stabilize SOC, an essential component of global climate regulation.A recent review published in Carbon Resear...Read More -
2025-12-10SCBG Summarizes the Applications of Geminiviruses in Synthetic BiologyResearchers from the South China Botanical Garden published a review that systematically summarizes the development and core applications of geminivirus vectors from VIGS to synthetic biology. This work provides critical technical references for crop improvement and biopharmaceuticals and envisions prospects, underscoring their potential in brid... Geminiviruses, the largest plant DNA virus family, cause devastating diseases in crops worldwide. However, the specialties of geminiviruses, such as compact genomes and efficient replication machinery, make them indispensable tools in molecular biology and biotechnology. Recently, Dr. Shulin Deng’s group from the South China Botanical Garden (S...Read More -
2025-12-10Calibrating the measurement of “Invisible carbon pool” of soils: A systematic benchmarking of methodologies cross-study synthesisThis first systematic benchmarking study provides a quantitative framework to harmonize global amino-sugar data, overcoming a key methodological barrier in synthesizing soil microbial necromass carbon measurements. We demonstrate that GC and HPLC show strong overall correlation, yet GC is more precise for C/N-rich soils while HPLC offers higher ... Comprehensive evaluation of analytical methods establishes a “common ruler” for soil carbon sequestration researchSoil represents the largest carbon reservoir in terrestrial ecosystems. A significant portion of stable soil carbon does not originate directly from plant residues but rather from microbial necromass, forming an “invisible microbi...Read More
