Project description:We present a genome assembly from an individual Alitta virens (the King Ragworm; Annelida; Polychaeta; Phyllodocida; Nereididae). The genome sequence is 671.2 megabases in span. Most of the assembly is scaffolded into 14 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 15.83 kilobases in length.
Project description:We present a genome assembly from an individual scale worm, Harmothoe impar; Annelida; Polychaeta; Phyllodocida; Polynoidae). The genome sequence is 1,512.3 megabases in span. Most of the assembly is scaffolded into 18 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 15.37 kilobases in length.
Project description:We present a genome assembly from an individual Lepidonotus clava (scale worm; Annelida; Polychaeta; Phyllodocida; Polynoidae). The genome sequence is 1,044 megabases in span. Most of the assembly is scaffolded into 18 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 15.6 kilobases in length.
Project description:We present a genome assembly from an individual Lineus longissimus (the bootlace worm; Nemertea; Pilidiophora; Heteronemertea; Lineidae). The genome sequence is 391 megabases in span. The majority of the assembly is scaffolded into 19 chromosomal pseudomolecules.
Project description:Urechis unicinctus is mainly distributed in Japan, north Korea and the Yellow Sea and the coast of Bohai Bay in China, and its nutrition is rich. The body of Urechis unicinctus contains many types of bioactive polypeptides, such as plasmin and tachykinin, which hold high economic and medicinal values. Therefore, the study of Urechis unicinctus has great significance. But the genome of Urechis unicinctus remains unavailable till now. To further understand the evolution of Urechis unicinctus and determine more effective application of it, we assembled the first draft genome sequence and the assembly of Urechis unicinctus. The dataset can be assessed from the BioProject at NCBI (https://www.ncbi.nlm.nih.gov/bioproject/?term=Urechisunicinctus).
Project description:We present a genome assembly from an individual Sthenelais limicola (the segmented worm; Annelida; Polychaeta; Phyllodocida; Sigalionidae). The genome sequence is 1,131 megabases in span. Most of the assembly is scaffolded into nine chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.7 kilobases in length.
Project description:The coding-complete severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome sequences from 15 nasopharyngeal swabs collected in Addis Ababa, Ethiopia, during the period from December 2020 to March 2021 were determined using Illumina MiSeq technology. A sequence analysis identified that the B.1 SARS-CoV-2 lineage was most prevalent with the worrying emergence of B.1.1.7 in June 2021.
Project description:Complete mitochondrial genome sequence of the giant mud worm Paraleonnates uschakovi (Polychaeta: Nereididae) was determined in this study for the first time. The mitogenome of P. uschakovi is 15,540 bp in length. It has 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a non-coding region. Mitogenome analysis of P. uschakovi showed inversion in the positions of three tRNAs compared to the mitogenome sequences of Perinereis aibuhitensis, P. nuntia and Platynereis dumerilii. The phylogenetic position of P. uschakovi compared to 15 selected polychaetes was investigated. P. uschakovi was grouped into the family of Nereididae. It is closely related to the clade containing Tylorrhynchus heterochaetus and Namalycastis abiuma.
Project description:Hemigrapsus penicillatus is a small grapsoid crab which is found in Japan, Taiwan, Korea, and China coasts. In this study a complete mitogenome of Korean H. penicillatus was analyzed and phylogenetic relationships in the family Varunidae were investigated. The mitogenome size is 16,486 bp with 34.1% A, 18.1% C, 11.4% G, and 36.4% T nucleotide distributions. Genome structure and gene orientations are identical with previous records from the family and mitochondrial protein-coding gene based phylogenetic tree suggested that the closest species to H. penicillatus is H. sanguineus. This is the second complete mitogenome record from the genus Hemigrapsus and the first record for the species.
