• Can Fat be "Tasted" in the Gastrointestinal Tract of Goats?

  In a recent study, PhD. ZHOU Chuanshe and his group from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA), led by professor TAN Zhiliang, have reported that the GIT of Goats have the potential to "taste" dietary fat.This team studied the GPR120 in ruminants for the first time, and proved that g-GPR120 mediated LCFA chemosensing mechanism is widely present in the GIT of goats.

  First Step of Root Exudate Utilization by Rhizosphere Microorganisms Revealed by 13C Labeling of Rice

  the research group from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) performed 13C pulse-chase labeling of wetland rice at five growth stages under field conditions. They tested two hypotheses: 1) root exudates and their microbial utilization changes during plant growth, and 2) rhizosphere bacteria outcompete fungi for initial uptake of root exudates because the reduced oxygen conditions have a repressive effect on fungi. We performed 6 hours of 13C pulse-chase labeling of wetland rice at five growth stages (active root growth (21 days after transplanting), rapid shoot growth (37 and 45 days after transplanting), and rapid reproduction (53 and 63 days after transplanting)) under field conditions. To test the first hypothesis, the pattern of 13C photosynthate distribution to shoot, roots, total soil organic matter, and microbial biomass were measured different stages of rice growth.

  Soil Erosion Rates in Karst Peak-cluster Depression Basins of Northwest Guangxi, China

  In a paper in Geomorphology, researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) revised Universal Soil Loss Equation (RUSLE) to estimate the annual soil erosion rates on hillslopes and compared them with 137Cs budget in the depressions at two typical karst peak-cluster depression basins (named GZ1 and GZ2 basin).

• Nitrogen Removal in Myriophyllum Aquaticum Mesocosm for Swine Wastewater Treatment

  In recent years, environmental pollution problems caused by swine production have created substantial concern in China.Swine wastewater is characterized by high levels of ammonia nitrogen (NH4+-N), suspended solids (SS), and chemical oxygen demand (COD). Using a N mass balance method, researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) investigated nitrogen removal processes

  L-Cysteine: Physiological and Nutritional Function in Host Health

  a research team led by Prof. YIN Yulong, from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) has reviewed the metabolic pathways of L-cysteine catabolism to GSH, H2S, and taurine, and corresponding nutritional implications in host health. L-cysteine is a nutritionally semi-essential amino acid.

• Migratory Waterbirds Significantly Influenced by Coastal Habitat Changes in Yangtze River Estuary

  Researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) employ remote sensing, geographic information systems (GIS) and statistical techniques to analyze the relationship between waterbird population dynamics and the changes in their habitats within the past decades in the Chongming Dongtan wetlands in the lower reaches of the Yangtze River. The team found that natural and artificial wetlands were both important to migratory waterbirds during the peak of migration and wintering, and waterbird populations were significantly correlated with their habitat changes both in natural and artificial wetlands.

• Whether the Biomasses of Soil Nematode Genera Can be Used as Weighting Factors for the Calculation of Nematode Community Indices

  No methodology has been developed to re-assess the cp scale and weighting system of nematodes. A team of researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) employed three data sets to calculate the indices using guild-based weighting and genus-based weighting.
