Abstract

In 2022, during potato cyst nematode surveys in several departments of Bolivia, the potato cyst nematode Globodera ellingtonae Handoo et al., 2012 was detected for the first time in Bolivia from potato fields located in the Department of Tarija. Cysts and second-stage juveniles of the Bolivian populations were morphologically and morphometrically similar to those of the USA (Oregon and Idaho) and Argentina. Nine new ITS rRNA, 15 COI, 13 cytb gene sequences of G. ellingtonae from ten Bolivian populations were obtained in this study. The phylogenetic analyses of the ITS rRNA and cytb genes showed that all Bolivian sequences clustered together and formed a major clade with other G. ellingtonae sequences from Argentina, Chile and the USA. Molecular results confirmed the hypothesis that the mountain region in southern Bolivia, northwest Argentina and northern Chile could be considered as an ancient centre of origin of G. ellingtonae. The present molecular results suggested that G. ellingtonae was likely introduced into the USA from Chile, rather than from Bolivia and Argentina.

马铃薯胞囊线虫的分子特征，Globodera ellingtonae Handoo等人，2012（Tylenchida：异脊线虫科），来自玻利维亚

2022年，在玻利维亚多个省的马铃薯囊肿线虫调查中，在玻利维亚Tarija省的马铃薯田首次发现了Globodera ellingtonae Handoo等，2012。玻利维亚种群的包囊和第二阶段幼鱼在形态和形态计量学上与美国(俄勒冈州和爱达荷州)和阿根廷的相似。从玻利维亚10个种群中获得了9个新的ITS rRNA、15个COI、13个cytb基因序列。ITS rRNA和cytb基因的系统发育分析表明，所有玻利维亚序列聚集在一起，与来自阿根廷、智利和美国的G. ellingtonae序列形成一个主进化支。分子结果证实了玻利维亚南部、阿根廷西北部和智利北部的山区可能被认为是G. ellingtonae的古代起源中心的假设。目前的分子结果表明，G. ellingtonae可能是从智利传入美国的，而不是从玻利维亚和阿根廷。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
