The embryonic cell lineage of the nematode Rhabditophanes sp.
It is proposed that an early symmetry-breaking event in nematodes of clade IV-V is a major developmental constraint which shapes their asymmetric cell lineage with strong left-right asymmetry. Expand
Embryonic cell lineage of the marine nematode Pellioditis marina.
The results reveal that there is more than one way to build a nematode, and the fate distribution pattern in a cell lineage could be a compromise between minimizing the number of specification events by monoclonal specification and minimizing the need for migrations by forming the cells close at their final position.

Occurrence of novel verrucomicrobial species, endosymbiotic and associated with parthenogenesis in Xiphinema americanum-group species (Nematoda, Longidoridae).
A new genus, 'Candidatus Xiphinematobacter' gen. nov., along with three new candidate verrucomicrobial species, are described, the first endosymbiotic species described among the Verrucomicrobia. Expand
Nematode systematics: past, present and future.
The future of nematode taxonomy will depend on the funding opportunities provided by national and international authorities and molecular techniques have made systematics again exciting; when combined with the more traditional morphological approach, they will lead to new insights. Expand
The Xiphinema americanum-group (Nematoda : Longidoridae). 2. Observations on Xiphinema brevicollum Lordello & da Costa, 1961 and comments on the group
A critical review of the article of Lamberti et al. (1992) with descriptions of X. brevu:ollum, X. diffusum, and three new species, which show to be c10sely related to each other, and a detailed characterization of the Xiphinema americanum-group. Expand
Use of the Verrucomicrobia-Specific Probe EUB338-III and Fluorescent In Situ Hybridization for Detection of “Candidatus Xiphinematobacter” Cells in Nematode Hosts
ABSTRACT Fluorescent in situ hybridization with a 16S rRNA probe specific for Verrucomicrobia was used to (i) confirm the division-level identity of and (ii) study the behavior of the obligateExpand
The Oesophageal Gland Nuclei of Longidoridae (Dorylaimida)
The results support the subdivision of Longidoridae into two subfamilies; Xiphinema represents a more derived stage than either of the other genera and Longidorella not belong to this family. Expand
A phylogenetic approach to the classification of the longidoridae (Nematoda: Dorylaimida)
Through out-group comparison and comparison of the five genera listed above, the characteristics of longidorid ancestry are established and the resulting cladogram is used as a basis for a new classification of the family. Expand
The use of egg morphology, recently suggested to be a key taxonomic criterion within the genus Eulimnadia, is here criticized, on the basis of material identified as E. cylindrova from several North American populations. Expand
