植物基因转录起始频率分析

利用UniGene数据库转录本序列数据,通过生物信息学方法,对已有全长mRNA序列数据的基因进行其转录本5'端序列的比对,获得该基因编码区前所有转录本的启始位点信息.通过7种植物17437个基因的分析表明,植物基因平均在171 bp(mRNA水平上)或174 bp(基因组水平上)的区间内转录启始,转录频率分布基本呈正态分布.为此我们研发了基因转录启始频率分析程序包PIFMaker,并基于以上分析获得的数据,建立了植物基因转录频率数据库(PIFdb,http://ibi.zju.edu.cn/bioinplant/).本研究分析基于该数据库第2版(Release 2.0)的数据.
