摘　　要：TCP蛋白家族是一类植物特有的转录因子家族，参与多种生理生化过程，具有重要的调控作用。本文利用生物信息学方法对苹果TCP转录因子家族成员、基因分类、基因结构、染色体定位、系统进化关系和结构域序列保守性进行了预测和分析。结果表明，苹果TCP基因家族包含52个成员，分为3类：ClassⅠ、ClassⅡ和ClassⅢ；MdTCP蛋白含有115-612个氨基酸，等电点为5．41-10．65；除3号染色体外，其余16条染色体均有MdTCP基因分布，其中5号染色体最多，有7个。TCP protein family is a large transcriptional regulator family in plant.They participate in many physiological and biochemical processes and play important regulatory effects.The family members, gene classification and structure,chromosome location,phylogenetic relationship and conserved structure do-mains of MdTCP were predicted and analyzed with bioinformatics method.There were 52 TCP family mem-bers,which were divided into 3 groups of ClassⅠ,ClassⅡand ClassⅢ.MdTCP protein contained 115 -612 amino acids with the isoelectric point of 5.41 -10.65.MdTCP genes were distributed on 16 chromosomes ex-cept Chr3 .Chr5 encompassed the most MdTCP gene number of 7 .
