对5个基因间的两两比较分析和进化分析结果表明:该基因簇是通过一系列的串联基因复制事件而形成;
Comparative analysis and evolutionary analysis of the clustered genes and other peroxidase family members revealed that the gene cluster occurred by tandemly gene duplications(from osp5 to osp1 );
这7个类似还原酶的基因为串联排列。
The 7 DFR-like genes were found to be arranged in a tandem array.
“这是第一个重要的研究,它解释了主宰调解员基因中微小的变化可以引发串联的其它基因的新陈代谢变化,”主作者Tim Spector在声明中说。
"This is the first major study that shows how small changes in one master regulator gene can cause a cascade of other metabolic effects in other genes," said lead author Tim Spector in a statement.
