In a recent study published in Functional Ecology on 31 March 2025, researchers led by Prof. WANG Kelin from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences shed light on how the size and proximity of rock outcrops influence soil functions in these mountain ecosystems. The research team conducted a field study in mountainous karst regions of southwest China, a landscape characterized by numerous prominent rock outcrops. A total of 31 rock outcrops of varying sizes were selected and categorized into five diameter classes: 0-1 m, 1-2 m, 2-3 m, 3-4 m, and 4-5 m (FIGURE 1a). Plant litter and soil samples were collected at two distances (0-20 cm and 20-50 cm) (FIGURE 1b). Soil functions were assessed in five aspects, including nutrient provisioning, microbial growth efficiency, soil organic matter decomposition, nutrient cycling, and plant-microbe symbiosis.
A recent study led by Prof. Jianlin Shen from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, has revealed the significant environmental impacts of ammonia emissions from intensive dairy farms on atmospheric nitrogen deposition and aerosol pollution. The findings, published in the prestigious journal Agriculture, Ecosystems & Environment (2025), provide critical insights into mitigating air pollution and ecosystem eutrophication caused by intensive animal farming.
A research team led by Prof. Wu Jinshui from the Institute of Subtropical Agriculture, Chinese Academy of Sciences has decoded the intricate iron-carbon interactions governing soil organic carbon (SOC) stability, unveiling novel strategies to amplify agricultural carbon sequestration.
A new study led by Prof. Yin Yulong from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, conducted integrated snRNA-seq and spatial transcriptome analysis of the longissimus dorsi (LD) muscle between TB and Duroc pigs at 180 days, which revealed a discrepancy in the expression profile between TB and Duroc pigs with cellular heterogeneity and spatial specificity. This study, published in Journal of Cachexia, Sarcopenia and Muscle on March 13, highlights important contribution to metabolic regulation of interaction between various cell populations in skeletal muscle and provides potential secretory genes to be diagnostic and intervention targets for metabolic diseases in humans and meat quality in pigs. Guo Liu serves as the first author of this paper, while Prof. Li Fengna and Yin Yulong are the corresponding authors.
A research team led by Prof. Tan Zhiliang from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, has systematically confirmed the phenomenon of impaired intestinal starch digestion in ruminants, and have identified the low expression of Cholecystokinin B Receptor (CCKBR) in the Acinar Cells is associated with insufficient starch hydrolysis in ruminants.
ssociate Prof. Yan Qiongxian and Prof.Tan Zhiliang visited Suranaree University of Technology (SUT), located in Nakhon Ratchasima Province, Thailand, and held in-depth discussions with international cooperation partner Dr. Pramote Paengkoum's research team during August 20 to 22.
