Phylogenetic Relationships Among Xiphinema and Xiphidorus Nematode Species from Brazil Inferred from 18 S rDNA Sequences

  title={Phylogenetic Relationships Among Xiphinema and Xiphidorus Nematode Species from Brazil Inferred from 18 S rDNA Sequences},
  author={O M.G. and Berthon J.-f. and F. C.C.B.},
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 Xiphinema species. As with previous taxonomic studies that noted only minor morphological differences between… 

Figures and Tables from this paper

An integrative approach to the study of Xiphinema brevicolle Lordello and Da Costa 1961, supports its limited distribution worldwide (Nematoda: Longidoridae)
By using a phylogenetic framework, molecular and morphometric data of the topotype population it is demonstrated that certain of the published DNA sequences have been misidentified and belong to closely related species such as X. taylori, X. diffusum or unknown/unidentified species.
A molecular phylogenetic approach to Longidoridae (Nematoda: Dorylaimida)
The phylogenetic analyses did not support it as a sister group to Longidorus as previously inferred from morphology, and it was found that sequence-based and structural morphometric rRNA phylogenies were incongruent.
First report, morphological and molecular characterization of Xiphinema elongatum and X. pachtaicum (Nematoda, Longidoridae) from Ethiopia
Two most important ecto-plant parasitic nematodes of the genus Xiphinema were found and analysed from Melkassa Agricultural Research Center experimental station, Ethiopia and their delimitation and discrimination are presented.
Ribosomal and Mitochondrial DNA Analyses of Xiphinema americanum-Group Populations.
Analyses of 18S rDNA and mtDNA sequences underpin the classical taxonomic issues of the X. americanum-group and cast doubt on the degree of speciation within the group.
Xiphinema krugi, Species Complex or Complex of Cryptic Species?
This study suggests that X. krugi is a potential species complex comprised of at least four distinct genotypes, both between representative populations of the RFLP profiles and putative closely related Xiphinema species.
Genetic diversity, and description of a new dagger nematode, Xiphinema afratakhtehnsis sp. nov., (Dorylaimida: Longidoridae) in natural forests of southeastern Gorgan, northern Iran
The most prevalent dagger nematode recovered from rhizospheric soil samples of forest trees in the Afrātakhteh region of Golestan province (Iran) was Xiphinema afratakhtehnsis sp. nov. and it is
First report of Ditylenchus gallaeformans in Miconia albicans from the Brazilian Cerrado, State of Goiás
Miconia albicans (Melastomataceae), whose common name is canela-de-velha, is a native plant of the tropical region that is abundant in the Cerrado biome. A nematode species was found parasitizing M.
Different nematodes and plasmodiophorids as vectors of plant viruses
In any type of management practice, timely samplings of soil and plant samples, use of vector- and virus-free planting materials, deployment of resistant crop plants, weeds control, and use of chemical products are important steps in implementing a control strategy.


The Xiphinema americanum group. I. Putative species, their geographical occurrence and distribution, and regional polytomous identification keys for the group.
Summary. Problems associated with identification of species attributed to the Xiphinema americanum group are reviewed to provide a 'benchmark' for a European Economie Union funded research
A PCR primer set for determination of phylogenetic relationships of Bursaphelenchus species within the xylophilus group
The phylogenetic relationships of Bursaphelenchus conicaudatus with B. abruptus, B. fraudulentus, B. mucronatus and B. xylophilus species were analysed based on the DNA base sequences of 18S, 5.8S,
The occurrence and geographic distribution of Xiphinema and Xiphidorus species (Nematoda: Longidoridae) in Brazil
A dichotomous key for the identification of Xiphinema species reported in Brazil is presented and several of these spe-cies are important economically as they are efficient vec-tors of several members of the genus Nepovirus that cause diseases in a wide range of fruit and vegetable crops.
Phylogenetic Analyses of Meloidogyne Small Subunit rDNA.
The results show that SSU sequence data are useful in addressing deeper phylogeny within Meloidogyne, and that both M. ichinohei and M. artiellia are credible outgroups for phylogenetic analysis of speciations among the major species.
18S ribosomal RNA gene phylogeny for some Rhabditidae related to Caenorhabditis.
18S rDNA sequences cannot be used to resolve relationships between taxa as closely related as the Caenorhabditis species, and Parsimony, minimum-evolution, and maximum-likelihood methods strongly reject Andrássy's proposed phylogenetic classification based on adult morphological characters but support that of Sudhaus as one of a few possible phylogenies.
Phylogenetic Analysis of rDNA Sequences from Adenophorean Nematodes and Implications for the Adenophorea-Secernentea Controversy
Phylogenetic relationships of 13 adenophorean and 15 secementean nematodes were analyzed using morphological data and 18S rDNA sequences in parallel. Both data sets strongly supported monophyly of
A molecular evolutionary framework for the phylum Nematoda
It is suggested that animal parasitism arose independently at least four times, and plant parasitism three times, which indicates that convergent morphological evolution may be extensive and that present higher-level classification of the Nematoda will need revision.
The effect, after four years, of a change in biotope on the morphometrics of populations of Xiphinema diversicaudatum (Nematoda: Dorylaimoidea)
The published morphometrics of different populations of Xiphinema diversicaudatum (Micoletzky) Thorne are very variable and specimens from seven populations were remeasured to assess the effect of a change in biotope on their size and morphology.
Molecular analysis of nematode diversity and the evolution of parasitism.
How the application of molecular phylogenetics is helping to resolve some of the inconsistencies in morphological classification and phylogeny by establishing relationships between free-living and parasitic groups and showing possible patterns underlying the origins of parasitism is discussed.
New approaches to a better understanding of nematode phylogeny: molecular and developmental studies.
To determine whether differences in developmental processes can be used as markers for intraphyletic relationships, comparative studies of nematode embryogenesis have been performed and indicate that considerable deviations from the standard pattern found in the model system Caenorhabditis elegans exist.
