We sequenced, assembled, and annotated the complete mitochondrial genome of the seed beetle , which represents the first report in the tribe from the subfamily Bruchinae of Chrysomelidae. The circular mitochondrial genome of the species contains 15,727 bases, 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a non-coding region. The GC content of the genome is 25.3%, which is higher than any other reported mitochondrial genomes within Bruchinae. The 16S ribosomal RNA gene and the 12S ribosomal RNA gene are 1284 and 835 bp in length, respectively. 12 PCGs started with the typical ATN codon, except for ND1 initiated with TTG. Five PCGs have the typical stop codon of TAA or TGA, while the remainder PCGs are terminated with incomplete stop codons (TA or T). The phylogenetic analysis based on a combination of 13 genes of the mitochondrial genomes of six species of Bruchinae and 23 species from other 10 subfamilies of Chrysomelidae recovered a generally well resolved and strongly supported tree topology, which shows that has the basalmost position in Bruchinae.
我们对豆象甲的完整线粒体基因组进行了测序、组装和注释,这是叶甲科豆象亚科该族的首份报告。该物种的环状线粒体基因组包含15727个碱基、13个蛋白质编码基因(PCGs)、22个tRNA基因、2个rRNA基因和一个非编码区。基因组的GC含量为25.3%,高于豆象亚科内其他任何已报道的线粒体基因组。16S核糖体RNA基因和12S核糖体RNA基因的长度分别为1284和835 bp。12个PCGs以典型的ATN密码子起始,除了ND1以TTG起始。5个PCGs具有典型的TAA或TGA终止密码子,而其余PCGs以不完全终止密码子(TA或T)结束。基于豆象亚科6个物种以及叶甲科其他10个亚科23个物种的线粒体基因组13个基因组合的系统发育分析,得到了一个总体上解析良好且支持度高的树形拓扑结构,表明[物种名称]在豆象亚科中处于最基部的位置。
