借助MATLAB软件和最优完全子图算法,提取许展示NCBI数据库中烟草脉清病毒完整基因组(NC-003378.1)上微卫星分布特性.结果表明,计算出了各种1-碱基组～6-碱基组在完整基因组序列上重复出现次数和出现化置,并展示它们的分布规律(指数函数),烟草脉清病毒完整基因组上各种N-碱基组最大的重复出现次数,随N按指数函数数减少;各种N-碱基组最复出现次数由少到多排序的结果,重复出现次数随序号增加.该研究方法可以系统地运用到其他病毒完整基因组序列微卫星分布特性的提取和展示,从而为有效利用微卫星分布特性研究完整基因组的结构和功能、遗传和变异规律提供依据.
藉助MATLAB軟件和最優完全子圖算法,提取許展示NCBI數據庫中煙草脈清病毒完整基因組(NC-003378.1)上微衛星分佈特性.結果錶明,計算齣瞭各種1-堿基組～6-堿基組在完整基因組序列上重複齣現次數和齣現化置,併展示它們的分佈規律(指數函數),煙草脈清病毒完整基因組上各種N-堿基組最大的重複齣現次數,隨N按指數函數數減少;各種N-堿基組最複齣現次數由少到多排序的結果,重複齣現次數隨序號增加.該研究方法可以繫統地運用到其他病毒完整基因組序列微衛星分佈特性的提取和展示,從而為有效利用微衛星分佈特性研究完整基因組的結構和功能、遺傳和變異規律提供依據.

MATLAB software and optimal complete subgraph algorithm were used to extract and reveal the microsatellite distribution features in the complete genomes of the tobacco vein clearing virus(NC-003378.1)from the NCBI database.The results showed that the repetitions number and their location of the N-base group has been extracted and displayed.The largest repetitions of N-base group in the complete genomes of the tobacco vein clearing virus was decreased as the exponential function with the increasing of N.The method used in this study could be applied to the extraction and revealing of the microsatellite distribution features in the complete genomes of other viruses,thereby provided a basis for the research of the structure and the law of function,inheritance and variation by the using of the microsatellite distribution features.
