叶绿体基因组及其在樟科植物系统发育研究中的应用

樟科植物是被子植物中一个较大的木本植物类群，也是一个较为古老的类群，集轻工业、食用、材用、药用、观价值赏于一身，在我国林业史和园林史上占有重要地位。植物的系统发育研究可在阐明物种之间亲缘关系的同时，挖掘它们的共同祖先以及它们在进化过程中的分化和演化路径，揭示生物种群和物种的多样性及其时空分布。在概述樟科植物和叶绿体基因组的基础上，分析了利用叶绿体基因组对樟科植物进行系统发育研究的相关进展，以期为樟科植物的相关研究提供参考。

Chloroplast Genome and Its Application in Phylogenetic Studies of Lauraceae

Lauraceae is a large group of woody plants in Angiosperms, which is a relatively ancient group and is integrated with light industry, food, materials, medicine and ornamental, and occupies an important position in the history of forestry and landscape architecture in China. Phylogenetic studies of plants can clarify the relationship between species, excavate their common ancestors and their differentiation and evolution paths in the evolutionary process, and reveal the diversity of biological populations and species, as well as their distribution in geography and time. Based on the overview of the chloroplast genome and the chloroplast genome of Lauraceae, the advances on phylogenetic reserch of Lauraceae plants is reviewed in this paper, in order to provide theoretical guidance for the related studies of Lauraceae plants.
