摘要

在对伊朗土壤线虫的调查中，从苜蓿根际发现了一些已知的Ditylenchus属物种：Ditylenhus acute、Ditylencus myceliophagus和Ditylenchus tericolus。提供了这些物种的测量结果和插图。对来自伊朗的Diylenchus物种的28S rDNA区域的分子研究将它们置于不同的分支中。系统发育分析表明，破坏双足目是一个单系分类单元。此外，尖齿龙与破坏齿龙、蛛形齿龙、沙氏齿龙、波斯齿龙和大齿龙并列为一个分支。而食霉菌D.myceliophagus和梗霉菌D.tericolus形成一个单独的分支。文中给出了尖尾D.actus、食菌D.myceliophagus和梗尾D.tericolus的系统发育位置和形态计量学。

Morphological and molecular characters of three Ditylenchus species from Iran

During a survey of soil nematodes in Iran, some known species belonging to the genus Ditylenchus were recovered from the rhizosphere of alfalfa: Ditylenchus acutus, Ditylenchus myceliophagus and Ditylenchus terricolus. Measurements and illustrations are provided for these species. A molecular study of the 28S rDNA region of the Ditylenchus species from Iran placed them in separate clades. Phylogenetic analysis indicates that Ditylenchus destructor is a monophyletic taxon. In addition, D. acutus places together with D. destructor, Ditylenchus arachis, Ditylenchus sarvarae, Ditylenchus persicus and Ditylenchus halictus in a clade. While D. myceliophagus and D. terricolus form a separate clade. Phylogenetic positions and morphometrics of D. acutus, D. myceliophagus and D. terricolus are given.
