Described originally from Heilongjiang, China, is a potential pest of threatening bean plant in northern China. The complete mitochondrial genome of was sequenced and assembled, with a total length of 15,540 bp. Within this genome, 37 genes have been identified: 13 PCGs, 22 tRNAs, two rRNAs, and two putative control regions. Most PCGs terminate with TAA, while four genes (, , and ) use an incomplete 'T' and employs TAG as the stop codon. Compared to the mitogenome of the ancestral insect, displays significant gene rearrangement. However, it retains three conserved gene blocks in common with its related species, , both of which belong to the genus-group. The phylogenetic tree, constructed based on the entire mitogenome dataset of all thrips species available in NCBI, shows that the two species cluster closely together. This alignment might underscore the close link between gene arrangements and the phylogeny relationships.
最初在中国黑龙江被描述,是中国北方豆类植物的一种潜在害虫。对其线粒体全基因组进行了测序和组装,全长15540bp。在这个基因组中,已鉴定出37个基因:13个蛋白质编码基因(PCGs)、22个tRNA、2个rRNA和2个假定的控制区。大多数PCGs以TAA结尾,而四个基因(、、和)使用不完整的“T”,并且使用TAG作为终止密码子。与原始昆虫的线粒体基因组相比,显示出明显的基因重排。然而,它与相关物种共同保留了三个保守的基因块,这两个物种都属于属组。基于NCBI中所有蓟马物种的完整线粒体基因组数据集构建的系统发育树表明,这两个物种紧密聚类在一起。这种比对可能突出了基因排列与系统发育关系之间的紧密联系。
