真蝽（Hemiptera：Heteroptera）是形态学和生态学上最具多样性的昆虫类群之一，在半翅目（Hemiptera）亚目和异翅亚目（Heteroptera）下亚目之间的几个深层节点上，其生殖发育一直是人们关注的焦点。本研究收集了半翅目-异翅亚目昆虫53个分类群和3102个直向同源基因的基因组数据，并采用拼接和合并两种方法对它们的同源性进行了研究。引入双节点控制的数据过滤方法，减少不同基因之间的不一致性，从而提高系统发育重建的性能。这两种假说（Coleorrhyncha + Heteroptera）和（Coleorrhyncha + Aucheliorrhyncha）得到了各种分析的支持，其中前者更符合形态学证据。根据对具有强烈系统发育信号的基因进行的分歧时间估计，真正的错误的起源可以追溯到二叠纪的290-268 Ma，这是地球历史上大气氧浓度最高的时间。在这段时间内，至少有1007个无定形氨基酸被保留在现存真蝽的共同祖先中。这些分子多态性位于553个正向同源基因中，这表明现存真虫的共同祖先可能在基因组水平上经历了大规模的进化。
The phylogeny of true bugs (Hemiptera: Heteroptera), one of the most diverse insect groups in terms of morphology and ecology, has been the focus of attention for decades with respect to several deep nodes between the suborders of Hemiptera and the infraorders of Heteroptera. Here, we assembled a phylogenomic data set of 53 taxa and 3102 orthologous genes to investigate the phylogeny of Hemiptera–Heteroptera, and both concatenation and coalescent methods were used. A binode‐control approach for data filtering was introduced to reduce the incongruence between different genes, which can improve the performance of phylogenetic reconstruction. Both hypotheses (Coleorrhyncha + Heteroptera) and (Coleorrhyncha + Auchenorrhyncha) received support from various analyses, in which the former is more consistent with the morphological evidence. Based on a divergence time estimation performed on genes with a strong phylogenetic signal, the origin of true bugs was dated to 290–268 Ma in the Permian, the time in Earth's history with the highest concentration of atmospheric oxygen. During this time interval, at least 1007 apomorphic amino acids were retained in the common ancestor of the extant true bugs. These molecular apomorphies are located in 553 orthologous genes, which suggests the common ancestor of the extant true bugs may have experienced large‐scale evolution at the genome level.
