Abstract

Grapevine Pinot gris virus (GPGV) is a recently identified trichovirus infecting grapevines. Despite wide distribution, there is limited available information on epidemiology, transmission, and associated symptoms of grapevine leaf mottling and deformation. Occurrence and genetic diversity of GPGV variants were surveyed in an organically cultivated Hungarian vineyard that was planted between 1996 and 2014. Sequence analysis demonstrated the widespread presence and high variability of GPGV, and according to phylogenetic analyses, the Hungarian virus isolates were classified into three groups. Most of the identified variants clustered with the representative asymptomatic isolates, but all isolates from one grapevine cultivar grouped with representative isolates of clade B. Furthermore, one isolate clustered with representative isolates of clade C, and the identified clade C variant had previously undescribed polymorphisms.

匈牙利有机栽培葡萄园中葡萄灰皮诺病毒（GPGV）的遗传变异性

葡萄灰皮诺病毒（GPGV）是最近发现的一种感染葡萄树的三代病毒。尽管该病毒分布广泛，但有关流行病学、传播以及葡萄叶片斑驳和变形等相关症状的信息却十分有限。研究人员在 1996 年至 2014 年间种植的匈牙利有机栽培葡萄园中调查了 GPGV 变体的发生情况和遗传多样性。序列分析表明，GPGV 广泛存在且变异性很高，根据系统发育分析，匈牙利病毒分离物被分为三组。大多数已鉴定的变异株与代表性无症状分离株聚类，但来自一个葡萄栽培品种的所有分离株都与 B 支系的代表性分离株聚类。此外，有一个分离株与 C 支系的代表性分离株聚集在一起，已鉴定的 C 支系变异株具有以前未曾描述过的多态性。

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.
