Abstract

Actinidia latifolia, known for its high vitamin C content in fruits, is widely distributed in the subtropical and tropical regions of eastern and southern Asia. In this study, we sequenced the complete chloroplast (cp) genome sequence of A. latifolia to investigate its phylogenetic position in the gunus Actinidia. The complete cp genome sequence is 156,873 bp in length with 37.15% overall GC content and characterized by a typical quadripartite structure comprising one pair of inverted repeats (23,377 bp) separated by a small single-copy region (21,453 bp) and a large single-copy region (88,666 bp). The cp genome contains 132 unique genes, including 83 protein coding genes, 41 tRNA genes, and 8 rRNA genes. Phylogenetic analysis highly supported that A. latifolia evolutionarily close to A. eriantha.

摘要

猕猴桃以其水果中的高维生素C含量而闻名，广泛分布于东亚和南亚的亚热带和热带地区。在这项研究中，我们对A的完整叶绿体（cp）基因组序列进行了测序。阔叶菊调查其在猕猴桃中的系统发育位置。完整的cp基因组序列长度为156,873 bp，GC总含量为37.15％，其特征是典型的四方结构，包括一对反向重复序列（23,377 bp），该重复序列之间有一个小的单拷贝区域（21,453 bp）和一个大的单拷贝区域。复制区域（88,666 bp）。cp基因组包含132个独特基因，包括83个蛋白质编码基因，41个tRNA基因和8个rRNA基因。系统发育分析高度支持宽叶拟南芥进化接近eriantha。
