• Simulated Tillage Affects Microbial Autotrophic CO2 Fixation in Paddy and Upland Soils

  Physical disturbance introduced during soil management practices (such as tillage) may disintegrate the soil structure, causing pronounced changes in the soil microbial community involved in biogeochemical processes, such as carbon sequestration. The researchers found that soil disturbance altered the abundance of cbbL-carrying autotrophic bacteria, and this shift in autotrophic bacterial abundance was accompanied by significant changes in CO2 fixation, resulting in significant enhancement of soil organic carbon concentration.

• Emissions of NO and N2O in Wetland Microcosms for Swine Wastewater Treatment

  China is one of the world's largest producers of pork, and swine wastewater treatment is becoming an urgent issue in the country. In recent years, constructed wetlands (CWs), an effective and inexpensive technology, have been widely used to treat swine wastewater.Using a closed static chamber method, researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) estimated NO and N2O emissions in wetland microcosms vegetated with Myriophyllum elatinoides (WM), Alternanthera philoxeroides (WA), Eichhornia crassipes (WE) or without vegetation (NW) during the process of treating swine wastewater.

• Bacterial Laccase-like Genes and Fungal Laccase Gene are Present in Subtropical Arable Lands

  A team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) sampled from typical six sites containing the main soil types and agricultural land uses in subtropical China, and then detected the laccase activity and the abundance, diversity and composition of bacterial laccase-like genes and fungal laccase genes.

• A Non-toxic New Iron Supplement Candidate: Ferrous N-carbamylglycinate Chelate

  In order to improve the iron defiiency problems in new born piglets, the researcher group in Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) had designed a new iron chelate ferrous N-carbamylglycinate as an iron fortifier (patent No: 201310142525.4), which aimed to improve iron bioavailability and reduce extra digestion.

• How Ruminal Protein and Feed Intake Effect on Endogenous Nitrogen and Amino Acids Flow in Goats?

  Rumen is one of the most important parts for the ruminants, which help ruminant acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. In order to make a more accurate estimation of true N digestibility and know how much dietary N is needed to cover the requirement for EN and endogenous AA (ENAA) loss by the knowledge of EN loss, PhD. ZHOU Chuanshe and his group from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) ,led by professor TAN Zhiliang, carried out an experiment.

• MicroRNA-27b Overexpression Improves Mitochondrial Function and Insulin Resistance

  Mitochondria are the principal energy sources of the cell that convert nutrients into energy through cellular respiration. Recently, researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) and Clinical Laboratory Department, Hunan Guangxiu Hospital studied the effects of MicroRNA-27b (MiR-27b)-a target of resveratrol, on mitochondrial function in skeletal muscle and C2C12 cell myoblast.

• How Genotype and Dietary Protein Intake Co-regulate Expression of Amino Acid/Peptide Transporters in Porcine Skeletal Muscle?

  A balanced supply of dietary proteins and amino acids (AAs) is necessary for the optimal growth, development, and reproduction of animals.As pig strains may vary in their capacity to recognize changes in AA concentration in body fluids, the utilization of free AAs may also differ among pig strains. According to Ph.D candidate LIU Yingying from Institute of Subtropical Agriculture, Chinese Academy of Science(ISA), differences among different strains of pigs in their muscle growth, meat quality, and intermuscular adipose deposition, may lead to dietary protein-dependent differences in AA metabolism.

• Where does All the Water Go in Subtropical Fengcong Karst Areas of Southwest China?

  when rainfall falls on the karst system, where does water go? What flow path does the water take? What is the percentage of water can be used by humans? And will the climate extreme cause more severe water shortage in the karst area of southwest China?Using plot-scale rainfall simulations on a trench excavated to the epikarst lower boundary (with a depth of about 4 m), a team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA), investigated the rainfall partitioning pattern of a soil-mantled, humid subtropical soil-epikarst system characterized by shallow soils overlaying a highly irregular epikarst surface.

• Pig genotype, diet, and physiological stage interact on signaling pathways related to protein synthesis

  Prof. YIN Yulong's group from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) speculated that the difference between these two genotypes of pigs in their muscle growth, meat quality, and intermuscular adipose deposition may lead to dietary protein-dependent differences in protein deposition and related signaling pathways in different types of skeletal muscles.

• Early-weaning Effects Expression of Proteins Involved in Energy Production

  a study cooperated by Dr. XIONG Xia and Dr. YANG Huangsheng from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA)has found that early-weaning differentially affect the expression of proteins involved in energy production of enterocytes along the jejunal crypt-villus axis.
