Nematodes within the Xiphinema americanum species complex are economically important because they vector nepoviruses which cause considerable damage to a variety of agricultural crops. The taxonomy of X. americanum species complex is controversial, with the number of putative species being the subject of debate. Accurate phylogenetic knowledge of this group(More)
Bacterial mutualists can modulate the biochemical capacity of animals. Highly coevolved nutritional mutualists do this by synthesizing nutrients missing from the host's diet. Genomics tools have advanced the study of these partnerships. Here we examined the endosymbiont Xiphinematobacter (phylum Verrucomicrobia) from the dagger nematode Xiphinema(More)
Wolbachia, one of the most widespread endosymbionts, is a target for biological control of mosquito-borne diseases (malaria and dengue virus), and antibiotic elimination of infectious filarial nematodes. We sequenced and analyzed the genome of a new Wolbachia strain (wPpe) in the plant-parasitic nematode Pratylenchus penetrans. Phylogenomic analyses placed(More)
The evolution of animal mitochondrial (mt) genomes has resulted in a highly conserved structure: a single compact circular chromosome approximately 14 to 20 kb long. Within the last two decades exceptions to this conserved structure, such as the division of the genome into multiple chromosomes, have been reported in a diverse set of metazoans. We report on(More)
Nematode Collection and DNA Extraction Nematodes were collected following methods previously described [1]. Mixed-­‐stages of Anguina agrostis were obtained from infected bentgrass seed. Globodera ellingtonae eggs were obtained from cysts reared on potato in field microplots. A population of Xiphinema americanum originally obtained from a vineyard was(More)
Globodera ellingtonae, a new cyst nematode species recently detected in Oregon and confirmed to reproduce on potato, shares key morphological features with the two species of potato cyst nematode (PCN; G. rostochiensis and G. pallida) which are of quarantine concern. Currently no methods are available for the molecular diagnosis of this new Globodera(More)
BACKGROUND Serotonin (5-HT) and its receptors are present in central, the brain stem, and peripheral, the carotid body, tissues controlling the ventilatory responses to hypoxia. The exact action of serotonin and its nature are, however, unsettled. We hypothesized that the discrepant results on the ventilatory action of serotonin could be caused by the(More)
