Mitochondrial DNA A DNA Mapp Seq Anal. 2016;27(1):700-2. doi: 10.3109/19401736.2014.913150. Epub 2014 May 9.
The complete mitochondrial genome of Spizixos semitorques is 17,045 bp long with an A+T content of 55.52%, which composed of 13 typical protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and 2 extensive heteroplasmic control regions (CR1 and CR2). Genome organization of S. semitorques is similar to that of other birds. All of the PCGs started with ATG, except for cox1, which began with GTG. Six types of termination codons were used, canonical TAA and TAG termination codons are found in seven protein-coding genes, while AGA for nad1 and nad5, AGG for cox1, and the remaining genes (nad2, cox3, nad4) have incomplete termination codons (TA- or T- -). All tRNA genes have a typical clover-leaf structure. Furthermore, a minisatellite of 24 nucleotides (5'-CACAAAAATCAAACAAAAATACAA-3') with 2.9 tandem repeats at the end of CR2 were detected.
黑脸噪鹛的完整线粒体基因组长度为17,045 bp,A+T含量为55.52%,由13个典型的蛋白质编码基因、22个转运RNA(tRNA)基因、2个核糖体RNA(rRNA)基因和2个广泛的异质性控制区(CR1和CR2)组成。黑脸噪鹛的基因组组织与其他鸟类相似。所有蛋白质编码基因均以ATG起始,但细胞色素c氧化酶亚基1(cox1)以GTG起始。使用了六种类型的终止密码子,七个蛋白质编码基因中发现了典型的TAA和TAG终止密码子,而NADH脱氢酶亚基1(nad1)和NADH脱氢酶亚基5(nad5)的终止密码子为AGA,cox1的终止密码子为AGG,其余基因(nad2、细胞色素c氧化酶亚基3(cox3)、nad4)具有不完整的终止密码子(TA-或T--)。所有tRNA基因都具有典型的三叶草结构。此外,在CR2末端检测到一个24个核苷酸的小卫星(5'-CACAAAAATCAAACAAAAATACAA-3'),有2.9个串联重复。
