摘要

尽管最近在端粒研究方面取得了进展，端粒DNA组织对于一些昆虫目的代表仍然是未知的。在本研究中，染色体水平的基因组组装分析表明，（Linnaeus, 1758）（多翅目，皮翅目，海绵目）的土蜈蚣Labiaminor （Linnaeus, 1758）的端粒DNA由5bp的重复序列TTCGG/CCGAA组成。这是对皮翅目端粒DNA结构的首次记录。这一记录扩大了已知端粒序列的范围，因为TTCGG基序以前没有在昆虫中报道过。

Telomere DNA in the insect order Dermaptera and the first evidence for the non-canonical telomeric motif TTCGG in Arthropoda.

Despite recent advances in telomere research, the telomere DNA organization remains unknown for representatives of several insect orders. In this study, analysis of the chromosome-level genome assembly shows that the telomeric DNA of the earwig Labiaminor (Linnaeus, 1758) (Polyneoptera, Dermaptera, Spongiphoridae) consists of repeats of the 5 bp motif TTCGG/CCGAA. This is the first record describing the structure of telomeric DNA in the order Dermaptera. This record expands the spectrum of the known telomeric sequences, since the TTCGG motif has not been reported for insects previously.
