Abstract

Parietaria mottle virus (PMoV) is an emerging virus in Mediterranean countries, responsible for severe disease in tomato and pepper crops in the field and protected cultivation. The principal wild reservoir of PMoV is Parietaria officinalis, and only few additional wild plants have been described as natural reservoirs of the virus. During field survey in southern Italy, several plants of Phytolacca americana showing virus-like symptoms were collected. Serological and molecular assays showed that these plants were infected by PMoV. Sequence comparison of the movement protein gene of the PMoV isolate from P. americana showed the greatest similarity to the corresponding sequence from tomato plants growing nearby. These results indicate that P. ameriacana is a new natural host of PMoV, and further investigation is warranted to establish the potential of this host as reservoir of the virus in the field.

新宿主美洲商陆中Paritaria斑驳病毒的分子和血清学检测

顶叶斑驳病毒(PMoV)是地中海国家出现的一种新病毒，是造成大田和防护栽培番茄和辣椒作物严重病害的罪魁祸首。PMoV的主要野生宿主是顶孢虫(Parietaria officinalis)，只有少数其他野生植物被描述为病毒的天然宿主。在意大利南部的实地调查中，收集到几株美洲植物表现出病毒样症状。血清学和分子检测表明这些植物感染了PMoV。美洲稻PMoV分离物的运动蛋白基因序列与邻近番茄植株的运动蛋白基因序列相似性最大。这些结果表明美洲假单胞虫是PMoV的一种新的天然宿主，需要进一步研究以确定该宿主作为该病毒在田间的潜在宿主。

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.
