Snakes are one of the most important wildlife resources and are widely distributed. <i>Bungarus multicinctus</i> is a highly venomous snake and is distributed in central and southern China. In recent years, venomous snake bites have gradually increased. Genomic resources are significant for understanding the evolution of a species and the molecular mechanisms of toxin production. So far, the genomic resources of snakes are a rarity. In 2021 we collected a snake sample in Beiliu Longgukeng, Guangxi, which was identified as <i>Bungarus multicinctus</i> by morphological identification. Here, we present a highly contiguous <i>B. multicinctus</i> genome with a genome size of 1.51Gb. The repeat content in the genome is 40.15%, and the total length is more than 620Mb. A total of 24,869 functional genes were annotated. This study is of great significance for understanding the evolution of <i>B. multicinctus</i>, and also provides a molecular basis for the genes of the venom glands.

蛇类是一类极为重要的野生动物资源，分布范围广泛。银环蛇（Bungarus multicinctus）是剧毒蛇类，主要分布于中国中部及南部地区。近年来，毒蛇咬伤事件发生率逐年攀升。基因组资源对于解析物种演化历程以及毒素合成的分子机制具有重要意义。截至目前，公开报道的蛇类基因组资源仍较为匮乏。2021年，本研究团队在广西北流龙谷坑采集到一份蛇类样本，经形态学鉴定确认为银环蛇。本研究构建了高连续性的银环蛇基因组，组装基因组大小为1.51 Gb，其中重复序列占比为40.15%，总长度超过620 Mb，共注释得到24869个功能基因。本研究不仅为解析银环蛇的演化历程提供了关键数据支撑，同时也为其毒腺相关基因的功能研究提供了重要的分子依据。
