由郑小波教授主持的“十五”863课题“重要植物病原生物分子检测及试剂盒研制”取得重要进展,部分研究工作日前通过了江苏省科技厅组织的成果鉴定。本研究根据生物的核糖体基因的转录间隔区(internal transcribed spacer,ITS)的DNA序列在种内不同个体之间具有高度保守性、而种间差异较大及不同物种间线粒体DNA序列的差异等原理,测
Important progress has been made in the “Tenth Five-Year Plan” 863 Project “Molecular Plant Pathogen Detection and Kit Development” hosted by Professor Zheng Xiaobo. Some research work has recently passed the appraisal of achievements organized by Jiangsu Science and Technology Department. In this study, the DNA sequences of internal transcribed spacer (ITS) regions of biological ribosomal genes are highly conserved among individuals within the species, while the interspecies differences are large and the differences in mitochondrial DNA sequences between different species Principle, measurement
