We present the draft mitochondrial genomes (mitogenomes) of two (Mayr 1855) workers from two separate invasive populations detected in Western Australia (Perth OK569858) and Queensland (Brisbane OK5569859), Australia. The draft mitogenomes ranged between 16,657 and 17,090 bp and contained 37 genes (13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), and two ribosomal RNA (rRNA) genes). As with other arthropod mitogenomes, we observed high A + T content (A: 39.4-39.8%, T: 40.55-41.5%). We confirmed the species identity by molecular diagnostics based on the partial mtCOI gene that showed >99% similarity between the Australian populations and other sequences reported to date, and in the process identified putative origins of the invasive populations as Pakistan and India for the WA and Qld incursions respectively that suggested separate introductions.
我们展示了来自澳大利亚西澳大利亚州(珀斯OK569858)和昆士兰州(布里斯班OK5569859)两个不同入侵种群的两只工蚁(梅尔1855)的线粒体基因组草图(有丝分裂基因组)。草图有丝分裂基因组长度在16,657至17,090碱基对之间,包含37个基因(13个蛋白质编码基因(PCG)、22个转运RNA(tRNA)和两个核糖体RNA(rRNA)基因)。与其他节肢动物有丝分裂基因组一样,我们观察到较高的A+T含量(A:39.4 - 39.8%,T:40.55 - 41.5%)。我们通过基于部分mtCOI基因的分子诊断确认了物种身份,该基因显示澳大利亚种群与迄今报道的其他序列之间的相似度>99%,并在此过程中确定入侵种群的推定起源分别为西澳大利亚州入侵的巴基斯坦和昆士兰州入侵的印度,这表明是分别引入的。
