摘　　要：基于辣椒全基因组序列,对辣椒脱水响应元件结合因子(DREB)基因家族进行鉴定、系统分析、染色体定位,并对涝害胁迫下其表达特性进行研究。在辣椒基因组中鉴定出40个CaDREB基因,分布在12条染色体上,编码108~452个氨基酸。系统进化树分析结果表明,辣椒DREB基因分为3大类。胁迫数据分析结果表明,在涝害胁迫下,CaDREB家族中的一些基因表达发生变化。Based on the whole genome sequence of pepper,identification,phylogenetic analysis and chromosomal location were done for dehydration responsive element-binding factor(DREB)gene family of pepper,and its expression characteristics was studied under waterlogging stress conditions.The results showed that,40 CaDREB genes were identified and were distributed on 12 chromosomes,encoding 108-452 amino acids.Analysis of phylogenetic tree showed that,CaDREB genes from pepper were grouped into three classes.Stress data analysis showed that,the expression of some members of the CaDREB gene family altered under waterlogging stress conditions.
