Genome Size Estimation of Semenov (Coleoptera: Cerambycidae), an Endangered Species and a Korea Natural Monument.

We estimated the genome size of a relict longhorn beetle, Semenov (Cerambycidae: Prioninae)-the Korean natural monument no. 218 and a Class I endangered species-using a combination of flow cytometry and -mer analysis. The two independent methods enabled accurate estimation of the genome size in Cerambycidae for the first time. The genome size of was 1.8 ± 0.2 Gb, representing one of the largest cerambycid genomes studied to date. An accurate estimation of genome size of a critically endangered longhorned beetle is a major milestone in our understanding and characterization of the genome. Ultimately, the findings provide useful insight into insect genomics and genome size evolution, particularly among beetles.
