The spittlebug family Cercopidae (Hemiptera: Auchenorrhyncha: Cicadomorpha: Cercopoidea) is distributed worldwide. Some Cercopidae species are agricultural pests that are responsible for substantial economic damage. However, the genomics of spittlebugs has rarely been studied and their complete genome assembly is yet to be reported. Here, we present the draft reference genome of Callitettix versicolor Fabricius (Hemiptera: Cercopidae) at the chromosome level. The assembled draft genome was 974.99 Mb with a contig N50 of 5.63 Mb, and the longest contig being 24.54 Mb. Hi-C technology was used to obtain an approximately 958.71 Mb chromosome-level genome on 10 pseudochromosomes, which covered 98.33% of the assembly. Repeat sequences accounted for 38.88% of the genomic sequences. A total of 21,937 protein-coding genes were detected in the reference genome, 89.97% of which were annotated in public databases. The high-quality reference genome of C. versicolor reported in this study will provide a valuable genomic resource for future ecological and evolutionary studies of spittlebugs.
沫蝉科(半翅目:沫蝉总科:沫蝉科)分布于世界各地。一些沫蝉科物种是农业害虫,对经济造成了重大损害。然而,沫蝉的基因组学研究甚少,其完整的基因组组装尚未报道。在这里,我们在染色体水平上展示了彩色沫蝉(Callitettix versicolor Fabricius)的基因组草图。组装的基因组草图大小为 974.99 Mb,contig N50 为 5.63 Mb,最长的 contig 为 24.54 Mb。使用 Hi-C 技术,在 10 条假染色体上获得了大约 958.71 Mb 的染色体水平基因组,覆盖了组装基因组的 98.33%。重复序列占基因组序列的 38.88%。在参考基因组中检测到 21937 个蛋白质编码基因,其中 89.97%在公共数据库中得到注释。本研究报道的彩色沫蝉高质量参考基因组将为未来沫蝉的生态和进化研究提供有价值的基因组资源。
