摘要

We sequenced four complete mitochondrial genomes (mt genomes) of members of the honey bee genus Apis (A. cerana, A. dorsata, A. laboriosa, and A. mellifera ligustica). These four and other available mt genome sequences of Apis were used to scrutinize the within-genus genomic characteristics, gene arrangement, and phylogenetic relationships of Apis. Furthermore, phylogenetic performance of 15 individual genes and two concatenated gene combinations were tested to locate suitable genes for Apis phylogeny. Phylogenetic reconstruction using all concatenated protein-coding genes (PCGs) and rRNAs strongly supported the presence of three lineages in Apis: the sister lineages of cavity-nesting honey bees (A. cerana, A. mellifera, A. nigrocincta, and A. koschevnikovi) and the giant honey bees (A. dorsata and A. laboriosa), and a divergent lineage consisting of the dwarf honey bees (A. florea and A. andreniformis). Apis mt genomes revealed two gene arrangements, trnE-trnS(1) or trnS(1)-trnE in the tRNA block at the A+T-rich region and ND2 junction. The gene arrangement found in Apis are consistent with two independent derivations because the same arrangement was shared between non-sister species. Several number of two gene concatenation, along with the individual gene ND4, confirmed the current whole mt genome-based phylogeny with relatively strong support, signifying that these single and two gene combinations are sufficient for an extended within-genus phylogeny of Apis, without inclusion of additional genes.

Mellifera Ligustica）的四个完整的线粒体基因组（MT基因组）。这些四种和其他可用的API基因组序列用于仔细审查API的基因组特征，基因排列和系统发育关系。此外，测试15个单个基因的系统发育性能和两种级联基因组合以定位适合的APIS phylogy基因。使用所有连接的蛋白质编码基因（PCG）和RRNA的系统发育重建强烈支持API中的三个谱系的存在：腔嵌套蜂蜜蜜蜂的姐妹谱系（A.Cerana，A. Mellifera，A. Nigrocintya和A. Koschevnikovi ）和巨型蜂蜜蜜蜂（A. Dorsata和A.Galsiosa），以及由矮种蜂蜜蜜蜂（A.Forerea和A.和Reniformis）组成的不同谱系。 API MT基因组在A + T-区域和ND2结处揭示了两种基因布置，Trne-TrNS（1）或TrNS（1）-TRNe。 API中发现的基因布置与两个独立的衍生一致，因为在非姐妹物种之间共享相同的安排。几个两种基因级联以及单个基因ND4以及具有相对强烈的载体的当前整个MT基因组的系统发育，表示这些单一和两个基因组合足以用于延长的API内部文中系统内部，而不会包含额外的基因。
