| 摘 要： | 杂交和多倍化是促进植物进化的重要力量。大量研究表明,植物多倍化后基因组结构和基因表达模式发生了复杂的变化,包括染色体重排、序列消除、基因沉默、基因激活等现象。鉴于此,综述了植物多倍化后基因组结构和基因表达模式变化的研究进展,以期为了解植物进化的机制提供参考。

| Abstract: | Polyploidy is a prominent and significant force in the evolution of higher plants.Many studies have demonstrated that the complicated changes in genome structure and gene expression always occurred after polyploidization,including chromosomal recombination,sequence elimination,gene silencing and activation.In order to provide references for understanding the mechanisms of plant evolution,the characteristics of the changes of genome structure and gene expression in polyploid plants were summarized. |
