Treść
Due to its ability to transmit plant viruses, Paratrichodorus teres (Hooper, 1962) is recognized as an economically important trichodorid species. Morphological and molecular analyses (18S and 28S rDNA) were performed, and 10 new plant hosts are reported for Polish P. teres populations. Major morphological features and the measurements obtained for the investigated specimens were within the wide ranges indicated for this species. However, a more detailed comparative analysis of Polish and Iranian P. teres showed significant morphological differences, particularly, in the shape and the structure of the walls of pars proximalis vaginae and the shape of the rectum. Phylogenetic study based on the 18S rDNA data suggests positioning of the Polish P. teres sequences within a cluster of sequences originating from the Netherlands. A comparison of the 28S rDNA fragment from Polish populations with the only P. teres 28S rDNA sequence available (from Iran) in GenBank revealed a sequence variability of 9.3%. The variation across these two representatives was higher than in the case of many other pairs of Trichodoridae species. The results obtained on the Polish P. teres specimens are discussed in the framework of the species taxonomy and phylogenetic relationships.
