TCP蛋白是植物特有的转录因子家族之一,在植物生长和发育等多个过程起到重要作用。本研究利用生物信息学方法对砀山酥梨TCP基因家族成员、染色体定位、进化分析、亚组分类、保守域结构和保守元件进行了相关分析。结果显示,梨TCP基因家族含有34个成员;进化分析表明,根据进化树拓扑结构将其分为两类:ClassⅠ和ClassⅡ,其中ClassⅡ可被分为CYC/TB1和CIN两个小组。结构域分析表明,梨TCP基因家族TCP结构域高度保守;保守元件分析表明,梨TCP基因家族包含5个保守元件:元件1是TCP保守域;元件2为R结构域,元件3、4和5为功能尚未鉴定的结构域,所有梨TCP蛋白都含有元件1,ClassⅡ组中CYC/TB1小组包含特异元件2。以上结果将为今后揭示梨TCP基因的功能提供重要的理论基础。
TCP is one of the plant-specific transcription factors and plays an important role in many processes such as plant growth and development. In this study, bioinformatics methods were used to analyze the TCP gene family members, chromosome location, evolutionary analysis, subgroup classification, conserved domain structure and conserved components in Dangshansu pear. The results showed that the pear TCP gene family contains 34 members. Phylogenetic analysis shows that the TCP family is divided into two groups according to the topological structure of the phylogenetic tree: Class I and Class II, in which Class II can be divided into two groups: CYC / TB1 and CIN. The analysis of the domain showed that the TCP domain of the pear TCP gene family was highly conserved. The conserved components analysis showed that the pear TCP gene family contained five conserved components: the first conserved domain of TCP, the second conserved domain of R, For domains that have not been identified, all Pear TCP proteins contain element 1, and the CYC / TB1 subgroup of Class II contains the specific element 2. The above results will provide an important theoretical basis for revealing the function of pear TCP gene in the future.
