摘要
以菖蒲为外类群,对姜科物种进行比较基因组学分析,结果表明,姜、草果及砂仁在进化过程中经历并共享了至少4次全基因组加倍事件,且各物种基因组在分歧之后没有再发生加倍事件,各物种基因组受多倍化影响发生了大量的基因丢失。对姜科基因组复杂性的比较研究对其物种遗传基因功能创新具有重要意义,可为单子叶植物进化史研究提供参考。
The study does comparative genomic analysis of Zingiberaceae with calamus as an outgroup.The results show ginger,grass and amomum have experienced and shared at least 4 genome-wide doubling events in the course of evolution,and the doubling events haven’t occur again after the divergence of the genome of each species,and a large number of genes are lost due to the influence of polyploidy.The comparative study of genomic complexity of Zingiberaceae is of great significance for the innovation of genetic function of its species,and can provide reference for the study of the evolutionary history of monocotyledonous plants.
