- 比较该结果与之前的研究,提出了一种解释拟南芥基因倍增过程更合理的模型。
This paper suggests a new model to explain the process of gene duplication in Arabidopsis. - 采用新的数据和方法研究拟南芥基因组的基因倍增过程,通过分析串联基因倍增和大规模基因倍增的存在比例和同义置换率分布,并估计大规模倍增后基因流失的比例,揭示了拟南芥基因组一次非常明显的全基因组倍增,采用科学的方法佑计这次倍增发生在约8000万年前。
Based on new materials and methods, this paper analyses the tandem and segmental duplication, then estimates the num of the lost gene after gene duplication in the Arabidopsis gene family, and we find an evidence for the whole genome duplication in Arabidopsis which happened about 80 million years ago. - 摘要基因倍增指基因组中含有基因的DNA片段复制出一个或更多拷贝的过程,是进化出新物种的主要原因。
Gene duplication is defined as segment of DNA duplicate one or more copies, it is believed to be a major mechanism for the generation of evolutionary novelty.
