In order to analyze PI-PLC gene family in Lovell peach (Prunus persica L.),bioinformatics method was used based on the peach genome database to obtain peach PI-PLC family genes structure and their positions on chromosome and duplication information.PI-PLC proteins were classified according to their phylogenetic relationship.The results showed that five PI-PLC genes existed in the peach (P.persica L.) genome and located on two chromosomes.The results of conserved domains indicated that all peach PI-PLC proteins contained four conserved domains (EF,X,Y and C2).Phylogenetic analysis revealed that the peach PI-PLC gene family could be divided into four groups.%为了对桃(Prunus persica var.Lovell)中PI-PLC家族基因进行系统分析,利用桃基因组数据库,通过生物信息学手段,鉴定桃PI-PLC家族基因的基因结构、染色体定位和编码蛋白,通过序列比对进行进化和分类分析.结果表明,桃中含有5个PI-PLC家族基因,预测他们均含有9个外显子,分布于桃的2条染色体上.保守结构域分析结果显示,桃中PI-PLC蛋白均含有4个保守的EF、X、Y和C2结构域.进化树分析结果表明桃PI-PLC家族基因可分为4个亚家族.
