摘要

茎线虫 Tylenchorhynchus annulatus (Cassidy, 1930) Golden, 1971 是一种广泛分布的植物寄生虫，与多种主要农作物有关。在目前的工作中，对从美国佛罗里达州大沼泽地甘蔗田中检测到的 T. annulatus 种群进行了形态学和分子鉴定。此外，还对来自中国、印度尼西亚、伊朗、韩国、尼日尔、尼日利亚、坦桑尼亚和美国的矮秆线虫种群进行了比较研究，这些种群被不同的研究小组从形态学和分子学上鉴定为 T. agri、T. annulatus 或 T. crassicaudatus。然而，在基于 rRNA 基因序列（28S 和 ITS）的系统发生树中，这些种群被分为两个支持率最高的支系。一个支系包括来自中国、印度尼西亚、伊朗、尼日利亚、韩国、坦桑尼亚和美国的种群，而另一个支系仅包括来自美国的种群。这项研究还有力地支持了 T. crassicaudatus 是 T. annulatus 的初级异名这一观点。

A taxonomic update on Tylenchorhynchus annulatus (Nematoda: Dolichodoridae), a widely distributed stunt nematode species

The stunt nematode species, Tylenchorhynchus annulatus (Cassidy, 1930) Golden, 1971, is a widely distributed plant parasite found associated with various major agricultural crops. In the current work, a population of T. annulatus detected from a sugarcane field in Everglades, Florida, USA, was morphologically and molecularly characterised. A comparative study was also done including the stunt nematode populations identified morphologically and molecularly by different research groups as T. agri, T. annulatus or T. crassicaudatus from China, Indonesia, Iran, Korea, Niger, Nigeria, Tanzania and the USA, revealing highly similar morphology and overlapping morphometric data among the populations. However, these populations were found separated into two maximally supported clades in phylogenetic trees based on rRNA gene sequences (28S and ITS). One clade comprised populations from China, Indonesia, Iran, Nigeria, South Korea, Tanzania and the USA, and the other clade only populations from the USA. This study also strongly supported the view that T. crassicaudatus is a junior synonym of T. annulatus.

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.
