Abstract

During 2022, a new disease of bottle gourd, causing leaf mosaic and yellowing symptoms, was observed in a private garden in the Campania region, Southern Italy. Incidence of disease was high (up to 80% of plants with symptoms). Polymerase chain reaction (PCR) with coat protein specific primers to tomato leaf curl New Delhi virus (ToLCNDV) indicated association of a begomovirus with the disease. The sequence comparison and phylogenetic analysis of the complete DNA genome further revealed the virus as within ToLCNDV-ES strain. Nevertheless, phylogenetic relationships showed two distinctive subgroups among ToLCNDV-ES isolates, with subgroup I composed only of ToLCNDV-ES isolates identified in the Campania region, including the isolate found in bottle gourd. The possible evolutionary forces that determined evolution of the two subgroups within the ToLCNDV-ES strain, including the role of the vector and cultural practices, are briefly analyzed and discussed.

意大利发现番茄卷曲病新德里病毒首例报道

在2022年期间，在意大利南部坎帕尼亚地区的一个私人花园中观察到一种新的葫芦病，导致叶子马赛克和发黄症状。发病率高(高达80%的植物有症状)。番茄卷曲新德里病毒(ToLCNDV)外壳蛋白特异性引物的聚合酶链反应(PCR)表明该疾病与一种begomavirus有关。序列比较和全DNA基因组系统发育分析进一步证实该病毒属于ToLCNDV-ES毒株。然而，系统发育关系显示，在ToLCNDV-ES分离株中存在两个不同的亚群，其中亚群I仅由在坎帕尼亚地区发现的ToLCNDV-ES分离株组成，包括在葫芦中发现的分离株。本文简要分析和讨论了决定ToLCNDV-ES毒株内两个亚群进化的可能进化力量，包括媒介的作用和文化习俗。

期刊介绍： Phytopathologia Mediterranea is an international journal edited by the Mediterranean Phytopathological Union. The journal’s mission is the promotion of plant health for Mediterranean crops, climate and regions, safe food production, and the transfer of new knowledge on plant diseases and their sustainable management. The journal deals with all areas of plant pathology, including etiology, epidemiology, disease control, biochemical and physiological aspects, and utilization of molecular technologies. All types of plant pathogens are covered, including fungi, oomycetes, nematodes, protozoa, bacteria, phytoplasmas, viruses, and viroids. The journal also gives a special attention to research on mycotoxins, biological and integrated management of plant diseases, and the use of natural substances in disease and weed control. The journal focuses on pathology of Mediterranean crops grown throughout the world. The Editorial Board of Phytopathologia Mediterranea has recently been reorganised, under two Editors-in-Chief and with an increased number of editors.
