摘　　要：本研究旨在分析和鉴定辣椒GATA转录因子的家族成员的生物信息学特征,为今后进一步的实验研究奠定基础。利用生物信息学手段,通过HMMER和SMART软件对辣椒GATA转录因子进行鉴定。利用Clustal X 1.83、MEGA5.05、GSDS、MEME等软件对辣椒GATA转录因子进行生物信息学分析。本研究鉴定出24个辣椒GATA转录因子家族成员。系统进化树的结果显示,24个GATA家族成员分为4个亚族。GSDS软件结果表明辣椒GATA转录因子的内含子、外显子分布情况。DNAMAN软件和MEME软件结果显示辣椒的大部分GATA转录因子是保守的。染色体定位软件Map Inspect分析表明,辣椒GATA转录因子在辣椒12条染色体上分布并不均匀。本研究鉴定并分析了辣椒GATA转录因子的生物信息学的特征,为以后继续研究其功能提供了一定的理论基础与现实意义。The aim of this study is to analyze and identify the bioinformatics features of the family members of GATA transcription factors in pepper, and lay a foundation for further experimental research in the future. By means of bioinformatics method, HMMER and SMART software were used to identify GATA transcription factors in pepper. Bioinformatics analysis of GATA transcription factors in pepper was carried out with Clustal X 1.83, MEGA5.05, GSDS and MEME. This study identified 24 members of the GATA transcription factor family in pepper. The results of phylogenetic tree showed that the 24 GATA family members could be divided into 4 subgroups. The results of GSDS software showed the distribution of intron and exon of GATA transcription factor in pepper. The results of DNAMAN software and MEME software showed that most of the GATA transcription factors in pepper were conserved. Chromosome localization software Maplnspect analysis showed that the GATA transcription factors of pepper were not evenly distributed on 12 chromosomes of pepper. This study identified and analyzed the bioinformatics characteristics of GATA transcription factors in pepper, which provided a theoretical basis and had practical significance for the further study.
