（河南农业大学生命科学学院郑州450002）摘要根据杨扇舟蛾颗粒体病毒（Clostera anachoreta Granulovirus,ClanGV）的全基因组序列，分析其基因组含有3个杆状病毒成纤维细胞生长因子（fibroblast growth factor，FGF）的同源ORFs。通过生物信息学软件及在线工具对ClanGVFGFs进行了分析，包括同源性、一级结构、二级结构和进化分析等。分析结果显示，测序得到的3个ClanGVFGFs转录方向不同，但都属于病毒转录早期基因；三者同源性相差较大；进化分析显示，ClanGVFGF3和NPV的FGFs进化关系较近，而ClanGVFGF1和ClanGVFGF2则与其它GV相应的FGF进化关系更近。

AbstractBased on the whole genome of Clostera anachoreta Granulovirus (ClanGV), the Fibroblast Growth Factor (FGF) genes of ClanGV were analyzed using biosoftware and online tools. The Results show that three ClanGVFGFs, which are all early expression genes, had different transcription directions. These ClanGVFGFs had low sequence homologies but shared a similar functional domain common to all identified FGFs. Evolutionary analysis proves that ClanGVFGF3 has a close relationship to NPVFGFs, however, ClanGVFGF1 and ClanGVFGF2 are closer to GVFGF1 and GVFGF2 respectively.
