Abstract

The Kroombit tinkerfrog ( ) is a stream-dwelling amphibian of the Myobatrachidae family. It is listed as Critically Endangered and is at high risk of extinction due to chytridiomycosis. Here, we provide the first genome assembly of the evolutionarily distinct genus. We sequenced PacBio HiFi reads to assemble a high-quality long-read genome and identified the mitochondrial genome. We also generated a global transcriptome from a tadpole to improve gene annotation. The genome was 5.52 Gb in length and consisted of 4,196 contigs with a contig N50 of 8.853 Mb and an L50 of 153. This study provides the first genomic resources for the Kroombit tinkerfrog to assist in future phylogenetic, environmental DNA, conservation breeding, and disease susceptibility studies.

摘要

克伦比丁蛙()是蟾科的一种溪流两栖动物。它被列为极危物种,由于壶菌病而面临极高的灭绝风险。在这里,我们提供了进化上独特的属的第一个基因组组装。我们对 PacBio HiFi 读长进行测序以组装高质量的长读长基因组,并鉴定了线粒体基因组。我们还从小蝌蚪生成了一个全转录组,以改进基因注释。基因组长度为 5.52 Gb,由 4196 个 contigs 组成,contig N50 为 8.853 Mb,L50 为 153。本研究为克伦比丁蛙提供了第一个基因组资源,以协助未来的系统发育、环境 DNA、保护繁殖和疾病易感性研究。
