Effect of transgenic soybean with sulfur - rich amino acids on soil microbial population structure
摘要
Abstract
Effects of transgenic soybeans on microbial population structure of rhizosphere soil were investigated under field conditions based on phospholipid fatty acid (PLFA) method. Two groups of transgenic soybeans with sulfur - rich amino acids were used. Results showed that soil microbial population in rhizosphere of transgenic lines changed significantly in both group A and B. 15 specific PLFAs were identified in group A, and 13 in group B. Correlation analysis found that microbial characterization of group A and the total concentration of PLFA' s of the transgenic line OE -8 were significantly higher than non -transgenic line, and so were 17-4 line and 57 line in group B. The dominant fifteen PLFA mown plots were 16: 0, 10Mel8: 0 and 18: 1ω7c in group A, and dominant thirteen PLFA were 15: 0, 16: 0 and 14Mel6: 0 in group B. The results suggested that the microbial population structure changed after planting transgenic soybeans.关键词
