Biology and genome of a newly discovered sibling species of Caenorhabditis elegans
TLDR
The biology and genome of Caenorhabditis inopinata are reported, a first sibling species of C. elegans, and genetic and molecular techniques for C. inop inata are developed, which provide an exciting new platform for comparative evolutionary studies. Expand
Specialist versus generalist life histories and nucleotide diversity in Caenorhabditis nematodes
TLDR
This work characterize sequence variation for 20 nuclear loci to investigate how C. japonica's life history shapes nucleotide diversity, and proposes that its specialist host association contributes to a smaller effective population size and lower genetic variation than host generalist Caenorhabditis species with outbreeding reproductive modes. Expand
New Plant-Parasitic Nematode from the Mostly Mycophagous Genus Bursaphelenchus Discovered inside Figs in Japan
TLDR
A new nematode species found in syconia of a fig species, Ficus variegata during a field survey of fig-associated nematodes in Japan, which has a well-developed stylet and pharyngeal glands and expands the knowledge of the potential morphological, physiological and developmental plasticity of the genus Bursaphelenchus. Expand
Assessment of Helminth Biodiversity in Wild Rats Using 18S rDNA Based Metagenomics
TLDR
The comparison of the results with those obtained using standard methods including microscopic observation of helminth parasites in the rat intestines and PCR amplification/sequencing of 18S rDNA from isolated single worms suggests that this new technique is reliable and useful to investigate parasite diversity. Expand
Comparative Genomics of Taphrina Fungi Causing Varying Degrees of Tumorous Deformity in Plants
TLDR
The genomes of four Taphrina species, which parasitize Prunus, Cerasus, and Populus hosts with varying severity of disease symptoms, are sequenced and it is revealed that these fungi may utilize multiple strategies in coping with the host environment. Expand
Description of two three-gendered nematode species in the new genus Auanema (Rhabditina) that are models for reproductive mode evolution
TLDR
Two new species of nematodes with trioecy are described, Auanema rhodensis and A. freiburgensis, which display convergent evolution in some features with parasitic nematode with complex life cycles, such as the production of few males after outcrossing and the obligatory development of dauers into self-propagating adults. Expand
Genome-Wide Analyses of Individual Strongyloides stercoralis (Nematoda: Rhabditoidea) Provide Insights into Population Structure and Reproductive Life Cycles
TLDR
The re-sequencing of the genomes of 33 individual S. stercoralis nematodes collected in Myanmar and Japan revealed an unambiguous geographical separation and sub-populations that correlated with the host geographical origin, particularly for the Myanmar samples. Expand
Simple and quick methods for nematode DNA preparation
TLDR
A DNA extraction kit, ISOHAIR® (Nippon Gene) was used to prepare nematode DNA for PCR and sequencing analyses, which was suitable for PCR amplification of near-full-length small subunit ribosomal RNA and partial mitochondrial COI genes. Expand
Stage-specific transcriptome of Bursaphelenchus xylophilus reveals temporal regulation of effector genes and roles of the dauer-like stages in the lifecycle
TLDR
More than 9000 genes are differentially expressed in at least one stage of the life cycle including genes involved in general nematode biology such as reproduction and moulting but also effector genes likely to be involved in parasitism. Expand
Differential responses of scavenging arthropods and vertebrates to forest loss maintain ecosystem function in a heterogeneous landscape
TLDR
Different responses to forest loss between burying beetles and scavenging vertebrates could maintain the carcass burying/removing function at a landscape level as forest loss influenced the disappearance rates of vertebrate carcasses. Expand
