• Straw Mulching Controls Heavy Metal Transportation

  a simulated rainfall experiment was conducted by researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) to determine the effect of different rates of rice straw mulching on the concentrations, transportation forms and cumulative amounts of Cd, Cu, Zn, and Ni transported via surface runoff.

• Fighting Diseases: Targeting Fat Within Muscle

  Recently, a team of researchers from China Agricultural University, the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) conducted a study to investigate the effects of low-protein diets (17% crude protein, CP ) supplemented with different BCAA ratios on the intramuscular fat (IMF) content and fatty acid composition in different location of skeletal muscles, including the longissimus dorsi, biceps femoris (BF), and psoas major muscle of growing pigs, and also examined the mRNA expression levels of genes involved in lipid metabolism in these muscle tissues.

• Can Alpha-Ketoglutarate Replace Glutamine in Piglet Enterocytes?

  researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) found that alpha-ketoglutarate (AKG) as a precursor of Gln and glutamate, is more inexpensive, soluble, and stable than Gln, thus it would potentially replace Gln in swine production. Especially, AKG, which serves as a central intermediate of the tricarboxylic acid cycle, as well as the carbon skeleton for the synthesis of glutamate and glutamine(Gln), plays a key role in the oxidation of fatty acids, amino acids, and glucose.

• 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.

• Maternal Chitosan Oligosaccharide Supplementation Affects Expression of Circadian Clock Genes and Hepatic Cholesterol Accumulation in Suckling Piglets

  In the paper in BIOLOGICAL RHYTHM RESEARCH, researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) used real-time PCR and Western Blot methods to clarify the expression of major circadian clock genes in the liver, and possible association with hepatic cholesterol accumulation in suckling piglets.

  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
