基于基因组信息结构特征的针叶树进化分析

onifers have diversified organizations of chloroplast genomes (cpDNAs), especially the ones with the two extremely reduced copies of the inverted repeat (IR). As the largest and the basal family of conifers, Pinus and Cryptomeria cpDNAs provide key insights into the evolutionary history of conifers. To reveal the various genomic organizations of conifers, main cpDNAs of conifers were utilized in comparative research. Pinus and Cryptomeria cpDNAs represented two types of IR structure, indicating that the cpDNA organization was very diverse in conifer plants. The availability of the conifer cpDNAs provided valuable information on the molecular phylogenetic study of conifers.
