Introduction Sipunculus nudus is the most known species in genus , distributed tropical and subtropical coastal waters. Methods PacBio sequencing Illumina were combined for whole-genome of S. . LC-MS/MS analysis was performed metabolomics Results Herein, we report a 1.75 Gb complete genome assembly with contig N50 size 450 kb based on strategy combining third-generation long-read sequencing. A ...

Sipunculus nudus is an important intertidal aquaculture species that can ingest organic matter from the surface sediment and shows a high transportation capacity in sediment. However, little known about influence of on microbial community exchange microbiota between intestine surrounding In this study, communities S. three kinds sediments were analyzed using high-throughput sequencing 16S rRNA ...

Daily irrigated, 80% pan replacement, and nonirrigated field plots of Kentucky bluegrass (Poa pratensis L.) were inoculated with a mixture of Steinernema carpocapsae (All strain) and Heterorhabditis bacteriophora (HP-88 strain) in 1988. In 1989, daily irrigated and nonirrigated plots were inoculated with HP-88 alone. The turf and associated soil contained populations of Tylenchorhynchus dubius,...

Since many studies have clarified the biological activity of polysaccharides, we investigated the effect of SNP which was the water-soluble polysaccharides extracted from Sipunculus nudus on Hepatoma HepG2-bearing Mice to verify the potential of SNP as an effective clinical agent for liver cancer therapy. SNP were administered at the doses of 50,100, and 200 mg/kg to HepG2-bearing mice to deter...

The present study analyses the distribution and diversity of sipunculan species inhabiting soft substrata in the Gulf of Valencia and Cape Nao (western Mediterranean) in relation to the characteristics of the sediment. Eighty-seven stations in 14 localities were sampled annually from 2004 to 2008. Nine species were reported, with Aspidosiphon (Aspidosiphon) muelleri being the dominant species i...

Examination of genetic data (mitochondrial cytochrome c oxidase I) for western Atlantic clingfishes revealed two distinct lineages within a group of individuals originally identified as Acyrtus artius. Subsequent investigation of preserved voucher specimens was conducted to reconcile the genetic data and the existing classification, which is based on morphology. In addition to discovering that ...

Synthesis of nuclear and cytoplasmic proteins was studied biochemically and autoradiographically in early loach (Misgurnus fossilis) and sea-urchin (Strongylocentrotus nudus) embryos. After incubation with [C]amino acids for 5-120 min the ratio of the specific activities of nuclear, mitochondrial and 12000g supernatant proteins was shown to be equal approximately to 6:1:2 in loach embryos and t...
