The raw sequencing data were quality control filtered, assembled, annotated and constructed a physical map. Furthermore, we systematically analyzed the codon usage bias of 52 protein-coding sequences. Our comprehensive analysis shows that the chloroplast genome was 159 897 bp in length, with a typical quadripartite structure consisting of a large single-copy region (LSC), a small single-copy region (SSC), and two inverted repeat regions (IR). The overall GC content of codons in the P. odorata chloroplast genome was 38.88%, with GC1>GC2>GC3, showing a preference for codons ending with A/U. The effective number of codons (ENC), the codon adaptation index (CAI), the codon bias index (CBI) and the frequency of optimal codons (Fop) ranged from 36.29 to 54.14, 0.10 to 0.30, -0.26 to 0.19, and 0.26 to 0.53, respectively. These analysis collectively indicated weak codon usage bias in the chloroplast genome of P. odorata . Neutrality plot analysis, ENC-plot analysis, and PR2-plot analysis revealed that codon usage bias in the P. odorata chloroplast genome resulted from both mutation pressure and selection pressure and was primarily determined by the selection pressure. A total of 10 optimal codons were identified. Our study established a fundamental framework for functional genomics and molecular breeding of P. odorata by providing:(i) theoretical foundations and molecular marker resources for further functional analysis of chloroplast genes, (ii) evolutionary studies, and (iii) molecular breeding within Polygonaceae., authors=SONG Zhi-jiao1 , LI E1 , YANG Ping1 , LI Gui-xiang2 , CHEN Wen-hua1 ,

bp,呈典型的四分体结构,包含大单拷贝区(Large single-copy region,LSC)、小单拷贝区(Small single-copy region,SSC)以及两个反向重复区(Inverted repeat,IR)。该叶绿体基因组总GC含量为38.88%,其中GC₁>GC₂>GC₃,偏好以A/U结尾。有效密码子数、密码子适应指数、密码子偏好指数、最优密码子使用频率的范围分别为36.29~54.14,0.10~0.30,-0.26~0.19和0.26~0.53,表明整体密码子使用偏好性较弱。中性绘图、ENC-plot和PR2-plot分析显示密码子使用偏好受突变和选择压力共同影响,且选择压力占主导,最终筛选出最优密码子10个。本研究为深入解析香辣蓼叶绿体基因功能、探讨其进化机制及指导分子育种提供了理论依据与标记资源。,

为解析香辣蓼(Persicaria odorata Lour.)叶绿体基因组密码子使用偏好性,本研究采用下一代测序技术对其叶绿体基因组测序。通过对原始数据过滤、组装、注释并构建物理图谱,系统分析52条蛋白质编码序列的密码子使用特征。结果表明:香辣蓼叶绿体基因组全长159 897 bp,呈典型的四分体结构,包含大单拷贝区(Large single-copy region,LSC)、小单拷贝区(Small single-copy region,SSC)以及两个反向重复区(Inverted repeat,IR)。该叶绿体基因组总GC含量为38.88%,其中GC₁>GC₂>GC₃,偏好以A/U结尾。有效密码子数、密码子适应指数、密码子偏好指数、最优密码子使用频率的范围分别为36.29~54.14,0.10~0.30,-0.26~0.19和0.26~0.53,表明整体密码子使用偏好性较弱。中性绘图、ENC-plot和PR2-plot分析显示密码子使用偏好受突变和选择压力共同影响,且选择压力占主导,最终筛选出最优密码子10个。本研究为深入解析香辣蓼叶绿体基因功能、探讨其进化机制及指导分子育种提供了理论依据与标记资源。

To investigate codon usage bias of Persicaria odorata , we sequenced the chloroplast genome of P. odorata using the Next-Generation Sequencing. The raw sequencing data were quality control filtered, assembled, annotated and constructed a physical map. Furthermore, we systematically analyzed the codon usage bias of 52 protein-coding sequences. Our comprehensive analysis shows that the chloroplast genome was 159 897 bp in length, with a typical quadripartite structure consisting of a large single-copy region (LSC), a small single-copy region (SSC), and two inverted repeat regions (IR). The overall GC content of codons in the P. odorata chloroplast genome was 38.88%, with GC1>GC2>GC3, showing a preference for codons ending with A/U. The effective number of codons (ENC), the codon adaptation index (CAI), the codon bias index (CBI) and the frequency of optimal codons (Fop) ranged from 36.29 to 54.14, 0.10 to 0.30, -0.26 to 0.19, and 0.26 to 0.53, respectively. These analysis collectively indicated weak codon usage bias in the chloroplast genome of P. odorata . Neutrality plot analysis, ENC-plot analysis, and PR2-plot analysis revealed that codon usage bias in the P. odorata chloroplast genome resulted from both mutation pressure and selection pressure and was primarily determined by the selection pressure. A total of 10 optimal codons were identified. Our study established a fundamental framework for functional genomics and molecular breeding of P. odorata by providing:(i) theoretical foundations and molecular marker resources for further functional analysis of chloroplast genes, (ii) evolutionary studies, and (iii) molecular breeding within Polygonaceae.
