intra-specific genetic variability of African yam bean (Sphenostylis stenocarpa Hochst Ex. A. Rich) “Harms" based on rbcL gene marker

The data presents the rbcL gene sequences of twenty-four accessions of S. stenocarpa. Table 1 shows the passport data and country of origin of the accessions whileTable 2 explains the submitted sequences to the NCBI GenBank, the assigned GenBank numbers, matched organisms and the sequence length (bp). Single nucleotide polymorphic (SNP) of 13 variable sites are represented in Table 3 while codon usage parameters including codon bias index (CBI), scaled chi square and G+C contents of coding and non-coding position are shown in Table 4. Table 5 summarizes the codon usage and amino acid residues of the species. The estimates of genetic diversity and Maximum Likelihood of Transition/Transversion Bias are pointed out in Table 6 and 7.

本数据集涵盖24份S. stenocarpa材料的核酮糖二磷酸羧化酶大亚基（rbcL）基因序列。表1展示了供试材料的种质基本信息与原产地；表2列明了提交至美国国家生物技术信息中心基因库（NCBI GenBank）的序列、分配获得的基因库登录号、匹配物种以及序列长度（碱基对，bp）。表3呈现了13个变异位点的单核苷酸多态性（Single nucleotide polymorphic, SNP）；表4展示了密码子使用相关参数，包括密码子偏倚指数（codon bias index, CBI）、标准化卡方值以及编码区与非编码区的G+C含量。表5汇总了该物种的密码子使用模式与氨基酸残基信息。表6与表7则列出了遗传多样性估算值以及转换/颠换偏倚的最大似然分析结果。
