对细菌、干旱、光、温度和高盐等各种生物和非生物胁迫,拟南芥中的早期脱水反应(ERD)基因被迅速诱导。拟南芥ERD(AtERD)基因已被鉴定出16个。基因编码区长度为504-2838个碱基对。它们编码137-745个氨基酸。本研究利用生物信息学的方法对AtERD基因的结构和启动子进行了分析,总结了AtERD基因的整体功能,并绘制了涉及AtERD基因的系统信号通路。AtERD9、AtERD11和AtERD13具有GST结构域。AtERD10和AtERD14具有Dehyd结构域。启动子区域包含32个光响应元件、23个ABA响应元件、5个干旱响应元件、5个分生组织表达相关元件和132个核心启动子元件。本研究为AtERD基因的后续研究提供了理论指导。
Early Responsive to Dehydration (ERD) genes are rapidly induced in response to various biotic and abiotic stresses, such as bacteria, drought, light, temperature and high salt in Arabidopsis thaliana. Sixteen ERD of Arabidopsis thaliana (AtERD) genes have been previously identified. The lengths of the coding region of the genes are 504–2838 bp. They encode 137–745 amino acids. In this study, the AtERD genes structure and promoter are analyzed through bioinformatics, and a overall function is summarized and a systematic signal pathway involving AtERD genes is mapped. AtERD9, AtERD11 and AtERD13 have the GST domain. AtERD10 and AtERD14 have the Dehyd domain. The promoters regions contain 32 light responsive elements, 23 ABA responsive elements, 5 drought responsive elements, 5 meristem expression related elements and 132 core promoter elements. The study provides a theoretical guidance for subsequent studies of AtERD genes.
