Abstract

Citrus aurantium (C. aurantium), belonging to the family Rutaceae, is usually utilized as a flavoring and acidifying agent for food. This study assembled and characterized the complete chloroplast (cp) genome of C. aurantium. The cp genome was 160,140 bp in length, containing a pair of inverted repeats (IRs, 26,996 bp each), which is separated by a large single-copy (LSC, 87,763 bp) region and a small single copy (SSC, 18,385 bp) region. The cp genome has overall GC content of 38.48% and 135 genes, composing of 90 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Phylogenetic analysis based on 25 cp genomes highly supported that C. aurantium was evolutionarily close to Cirtus sinensis (C. sinensis).

摘要

属于芸香科的桔ur（C。aurantium）通常用作食品的调味剂和酸化剂。本研究组装和特征的完全叶绿体（CP）基因组C.枳壳。cp基因组的长度为160,140 bp，包含一对反向重复序列（IR，每个26,996 bp），并由一个大的单拷贝（LSC，87,763 bp）区域和一个小的单拷贝（SSC，18,385 bp）隔开。地区。cp基因组的总GC含量为38.48％和135个基因，由90个蛋白质编码基因，37个tRNA基因和8个rRNA基因组成。系统发育分析基于高度支持了25个CP基因组酸橙是进化接近Cirtus冬虫夏草（冬虫夏草）。
