The Coleoptera order is the richest group among Metazoa, but its phylogenetics remains incompletely understood. Among Coleoptera, bioluminescence is found within the Elateroidea, but the evolution of this character remains a mystery. Mitochondrial DNA has been used extensively to reconstruct phylogenetic relationships, however, the evolution of a single gene does not always correspond to the species evolutionary history and the molecular marker choice is a key step in this type of analysis. To create a solid basis to better understand the evolutionary history of Coleoptera and its bioluminescence, we sequenced and comparatively analyzed the mitochondrial genome of the Brazilian luminescent click beetle Pyrophorus divergens (Coleoptera: Elateridae).
鞘翅目是后生动物中种类最丰富的类群,但其系统发育学仍未被完全理解。在鞘翅目中,发光现象存在于叩头虫总科内,但这一特征的进化仍是个谜。线粒体DNA已被广泛用于重建系统发育关系,然而,单个基因的进化并不总是与物种的进化历史相对应,并且分子标记的选择是这类分析中的关键步骤。为了建立一个坚实的基础以更好地理解鞘翅目及其发光现象的进化历史,我们对巴西发光叩甲Pyrophorus divergens(鞘翅目:叩甲科)的线粒体基因组进行了测序和比较分析。
