Identification and Phylogenetics Analysis of WRKY Transcription Factors Family in Pepper
摘要
Abstract
The WRKY transcription factors participate in the plant various kinds defense response,identifica-tion of WRKY will help to have a thorough understanding of process of regulate plant growth and development in plant. The pepper genome sequence and transcriptional profiling for phytophthora capsici were employed;the gene number,class,phylogenetics relation and conserved motif of WRKY transcription factor were analyzed in this study. As a result,at least 40 CaWRKYs genes were identified and then nominated as CaWRKY1 to CaWRKY40 based on their gene structures and phylogenesises. According to the number of WRKY domain and the type of zine finger,the identified CaWRKYs were grouped intoⅠ,Ⅱ(a),Ⅱ(b),Ⅱ(c),Ⅱ(d),Ⅱ(e) and Ⅲ class or subclass. There have been three different conversed motifs in pepper WRKY genes,the minimum and maximum motif width were 21 and 50,respectively. Pepper WRKY proteins contained from 151-747 amino acids and 378. 1 in average. The study provides a foundation for function and evolution of WRKY genes in pepper.关键词
