promoter element meaning in English

启动子元件

The pa7 fragment was sequenced and several motifs similar to prokaryotic promoter elements such as - lobox , - 35box and up box were found . the sd sequence which was bound by ribosome and atg site were also found . the pat fragment was blast in genebank , but there is no its " homological sequence
对pa7片段的序列分析发现其距5 ’端931bp ? 1091bp处具有原核生物典型基因启动子的保守结构- 10区和- 35区，以及翻译必需的sd序列和翻译起始位点等。
The study of the structure and function of these promoters will help not only to comprehend the development of seeds and the mechanisms of gene expression and organic substance accumulation but also search for some promoter elements useful for plant genetic engineering
对这类启动子的结构和功能元件的了解，有助于人们更加深入地理解高等植物基因表达调控机制，提高人们对植物种子发育过程及有机物在种子中积累机制的认识，而且可以为植物基因工程中生物反应器的研究提供有应用价值的启动子元件。
