Abstract

In a survey of plant-parasitic nematodes in agricultural fields, cyst-forming nematodes were found in soil planted bamboo in Korea. The aim of this study was to identify the cyst nematodes based on morphological and molecular characteristics. As the results, the morphology and morphometrics of cysts and second-stage juveniles (J2s) were consistent with those of previous descriptions of Heterodera koreana. In phylogenetic analyses based on DNA sequences, these cyst nematodes were clustered together with clade of H. koreana in internal transcribed spacer (ITS) region, and large subunit D2-D3 segments (LSU D2-D3). These nematodes were clustered together with clade of H. koreana in cytochrome c oxidase subunit I (COI) gene, but a haplotype was different when compared with previous reported haplotypes (haplotype A-C) in Japan. This study showed these cyst nematodes were identified as H. koreana, and a new haplotype of H. koreana is distributed in Korea. We suggest that the new haplotype of H. koreana name as haplotype D.

影响韩国竹子的 Heterodera koreana（天牛科：Heteroderidae）的单倍型多样性

在对农田中植物寄生线虫的调查中，在韩国种植竹子的土壤中发现了胞囊线虫。本研究的目的是根据形态和分子特征来鉴定囊线虫。结果表明，包囊和第二阶段幼虫（J2s）的形态和形态计量学特征与之前对 Heterodera koreana 的描述一致。在基于 DNA 序列的系统发育分析中，这些囊线虫在内部转录间隔区（ITS）和大亚基 D2-D3 片段（LSU D2-D3）上与 H. koreana 聚类在一起。这些线虫在细胞色素 c 氧化酶亚基 I（COI）基因上与 H. koreana 支系聚类，但与日本以前报道的单倍型（单倍型 A-C）相比，有一个单倍型不同。这项研究表明，这些胞囊线虫被鉴定为 H. koreana，而 H. koreana 的新单倍型分布在韩国。我们建议将 H. koreana 的新单倍型命名为单倍型 D。

期刊介绍： The European Journal of Plant Pathology is an international journal publishing original articles in English dealing with fundamental and applied aspects of plant pathology; considering disease in agricultural and horticultural crops, forestry, and in natural plant populations. The types of articles published are :Original Research at the molecular, physiological, whole-plant and population levels; Mini-reviews on topics which are timely and of global rather than national or regional significance; Short Communications for important research findings that can be presented in an abbreviated format; and Letters-to-the-Editor, where these raise issues related to articles previously published in the journal. Submissions relating to disease vector biology and integrated crop protection are welcome. However, routine screenings of plant protection products, varietal trials for disease resistance, and biological control agents are not published in the journal unless framed in the context of strategic approaches to disease management.
