Abstract

Tomato leaf curl New Delhi virus (ToLCNDV), a bipartite begomovirus, was first reported to infect tomato and has recently spread rapidly as an emerging disease to Cucurbitaceae crops. To date, the virus has been reported to infect more than 11 cucurbit crops, in 16 countries and regions, causing severe yield losses. In autumn 2022, ToLCNDV was first isolated from cucurbit plants in Southeastern coastal areas of China. Phylogenetic analysis established that these isolates belong to the Asian ToLCNDV clade, and shared high nucleotide identity and closest genetic relationship with the DNA-A sequence from the Chinese tomato-infecting ToLCNDV isolate (Accession no. OP356207) and the tomato New Delhi ToLCNDV-Severe isolate (Accession no. HM159454). In this review, we summarize the occurrence and distribution, host range, detection and diagnosis, control strategies, and genetic resistance of ToLCNDV in the Cucurbitaceae. We then summarize pathways that could be undertaken to improve our understanding of this emerging disease, with the objective to develop ToLCNDV-resistant cucurbit cultivars.

番茄卷叶新德里病毒:一种威胁瓜类生产的新兴植物begomavirus。
番茄卷曲新德里病毒(ToLCNDV)是一种双部begomvirus,首次报道感染番茄,近年来作为一种新发病害在葫芦科作物中迅速传播。迄今为止,据报道,该病毒感染了16个国家和地区的11种以上葫芦作物,造成严重的产量损失。2022年秋季,ToLCNDV首次从中国东南沿海地区的葫芦植物中分离出来。系统发育分析表明,这些分离株属于亚洲ToLCNDV分支,与侵染ToLCNDV的中国番茄分离株的DNA-A序列具有高核苷酸同源性和最密切的遗传关系。OP356207)和番茄新德里tolcndv严重分离株(加入号:HM159454)。本文综述了ToLCNDV在葫芦科的发生分布、寄主范围、检测诊断、防治策略及遗传抗性等方面的研究进展。然后,我们总结了可以采取的途径,以提高我们对这种新出现的疾病的理解,目的是开发抗tolcndv的葫芦品种。补充信息:在线版本包含补充资料,下载地址:10.1007/s42994-023-00118-4。
