摘要
从大肠杆菌感染的家蚕蛹提取 R N A, 用 R T P C R 方法扩增未知抗菌肽基因片段, 经过克隆测序, 获得了蚕抗菌肽 A 基因的部分片段164 bp , 为制备蚕抗菌肽 A 基因探针,
Total RNA was prepared from fat body of the silkworm, Bombyx mori , 9 hours after injected by E.coli K12D31. Single strand cDNA was synthesized by reverse transcription (RT). Partial fragments of cecropin A cDNA were obtained, cloned and sequenced, by PCR technique with a pair of degenerate primers designed according to the amino acid sequence of CM4 in Bombyx mori and cecropin A in Hyalophora . These laid a foundation for further research on preparation of the probes of cecropin A for screening the silkworm cDNA library.
