OBJECTIVE To localize and identify the insecticidal crystal protein genes (cry genes) in high-toxic Bacillus thuringiensis strain 4.0718. METHODS The genomic DNA of B. thuringiensis strain 4.0718 was isolated by pulse field gel electrophoresis (PFGE), and the PFGE pattern and plasmid pattern were characterized. The cry genes in the strain were analyzed by(More)
Many problems existed in the current grey system model-building, such as the rough exponential model, unsatisfied precision and the poor parallel computation ability. So it was very important to expand the current grey theory and find out an appropriate model building method. There were several ways to combine grey system with neural network, such as(More)
