The complete mitochondrial genome of Bryodema luctuosum luctuosum, which was collected from the Qinghai-Xizang Plateau of China, is reported here. It is 15,946 bp in length and contains 74.9% AT. All B. luctuosum luctuosum protein-coding sequences start with a typical ATN codon. The usual termination codon (TAA) and incomplete stop codons (T and TA) were found from 13 protein-coding genes. All tRNA genes could be folded into the typical cloverleaf secondary structure, excluding trnS(AGN) which forms another structure. The sizes of the large and small ribosomal RNA genes are 1316 and 835 bp, respectively. The AT content of the A+T-rich region is 84.8%.
本文报道了采自中国青藏高原的暗黑鳃金龟指名亚种(Bryodema luctuosum luctuosum)的完整线粒体基因组。其长度为15946 bp,AT含量为74.9%。暗黑鳃金龟指名亚种所有蛋白质编码序列均以典型的ATN密码子起始。从13个蛋白质编码基因中发现了常见的终止密码子(TAA)和不完整的终止密码子(T和TA)。除形成另一种结构的trnS(AGN)外,所有tRNA基因均可折叠成典型的三叶草二级结构。大、小核糖体RNA基因的大小分别为1316和835 bp。A+T富集区的AT含量为84.8%。
