Phylogenetic Relationships Among Xiphinema and Xiphidorus Nematode Species from Brazil Inferred from 18S rDNA Sequences.
Maximum likelihood trees produced from 18S rDNA sequences separated 14 Xiphinema and five Xiphidorus nematode species from Brazil into distinct groups that concurred with their current morphological taxonomic status. Species belonging to the X. americanum group (X. brevicolle, X. diffusum, X. oxycaudatum, and X. peruvianum) formed a single group that was clearly separated from the other Xiphine...
متن کاملMorphological Variation among 23 Xiphinema americanum Populations.
Morphometrics of 23 United States populations of Xiphinema americanum sensu lato, sharing the characteristics of an offset lip region and conoid tail, were examined and analyzed statistically by canonical discriminant analysis (CDA). Specimens were collected from Arkansas, Georgia, Tennessee, Mississippi, Florida, Oklahoma, California, and North Dakota. Eleven measurements and body ratios obtai...
متن کاملRemarkable Diversity and Prevalence of Dagger Nematodes of the Genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) in Olives Revealed by Integrative Approaches
The genus Xiphinema includes a remarkable group of invertebrates of the phylum Nematoda comprising ectoparasitic animals of many wild and cultivated plants. Damage is caused by direct feeding on root cells and by vectoring nepoviruses that cause diseases on several crops. Precise identification of Xiphinema species is critical for launching appropriate control measures. We make available the fi...
متن کاملDistribution of Xiphinema americanum and Related Species in North America.
All species of the Xiphinema americanum-group and their synonyms are listed. The North American species reported are listed by state or province. Among these species, X. rivesi has the most widely reported distribution. Six species (X. diffusum, X. floridae, X. laevistriatum, X. luci, X. shell, and X. tarjanense) have been reported from only Florida. The reports of X. pachtaicum, X. sheri, and ...
متن کاملAspects of Biology and Development of Xiphinema americanum and Related Species.
Identification of Xiphinema americanum-group nematodes is based on relatively subtle morphological and morphometric differences, many of which overlap. The significance and importance of these separations cannot be assessed without a basic understanding of the biological differences between species. Currently, information is accumulating on Xiphinema biology, development, and genetics that will...
