Abstract

Hippeastrum vittatum (L’Hér.) Herb. is a perennial herb in the Amaryllidaceae, which has been used as a medicinal and ornamental plant. Here, we assembled and characterized the complete chloroplast (cp) genome of H. vittatum by high throughput sequencing. As a result, the length of the complete cp genome is 158,082 bp with a canonical quadripartite structure, consists of a large single-copy region (LSC) of 86,165 bp, a small single-copy region (SSC) of 18,283 bp, and two inverted repeat (IR) regions of 26,817 bp, each. A total of 137 genes were identified, including 87 protein-coding genes, 42 tRNA genes, and 8 rRNA genes. The phylogenomic analysis was performed based on the complete cp genomes of 30 species, which revealed the closest relationship between H. vittatum and H. rutilum in the genus Hippeastrum.

摘要

Hippeastrum vittatum（L'Hér。）草本。是菊苣科多年生草本植物，已被用作药用和观赏植物。在这里，我们通过高通量测序组装和表征了H. vittatum的完整叶绿体（cp）基因组。结果，完整的cp基因组的长度为158,082 bp，具有规范的四方结构，由86,165 bp的大单拷贝区域（LSC），18,283 bp的小单拷贝区域（SSC）和两个每个反向重复（IR）区域为26,817 bp。共鉴定出137个基因，包括87个蛋白质编码基因，42个tRNA基因和8个rRNA基因。根据30种植物的完整cp基因组进行了系统进化分析，揭示了H. vittatum之间最紧密的关系和Hippeastrum属中的H. rutilum 。
