The detection of cucumber green mottle mosaic (CGMMV) in the Northern Territory (NT), Australia, in 2014 led to the introduction of strict quarantine measures for the importation of cucurbit seeds by the Australian federal government. Further detections in Queensland, Western Australia (WA), New South Wales and South Australia occurred in the period 2015-2020. To explore the diversity of the current Australian CGMMV population, 35 new coding sequence complete genomes for CGMMV isolates from Australian incursions and surveys were prepared for this study. In conjunction with published genomes from the NT and WA, sequence, phylogenetic, and genetic variation and variant analyses were performed, and the data were compared with those for international CGMMV isolates. Based on these analyses, it can be inferred that the Australian CGMMV population resulted from a single virus source via multiple introductions.
2014 年，澳大利亚北领地（NT）检测到黄瓜绿斑驳花叶病毒（CGMMV），联邦政府随后对进口葫芦科种子实施了严格的检疫措施。2015 年至 2020 年期间，昆士兰州、西澳大利亚州（WA）、新南威尔士州和南澳大利亚州也有进一步的检测发现。为了探索当前澳大利亚 CGMMV 群体的多样性，本研究对澳大利亚入侵和调查中 35 个新的 CGMMV 分离株的完整编码序列基因组进行了分析。结合 NT 和 WA 的已发表基因组，进行了序列、系统发育、遗传变异和变体分析，并将数据与国际 CGMMV 分离株进行了比较。基于这些分析，可以推断澳大利亚 CGMMV 种群是由单一病毒源通过多次传入形成的。
