The complete mitochondrial genome of a widely distributed pelagic ray, the Spinetail Devilray (Mobula japanica), consists of 18,880 bp with high A+T and low G content. Gene configuration and length is similar to other vertebrates and comprises 13 protein-coding genes, 2 rRNAs genes (12S and 16S rRNA), 22 tRNAs genes, and 1 major non-coding sequence, the control region. A remarkable feature in t...

The primary role of a protein coding gene is to encode amino acids. Therefore, synonymous sites of codons, which do not change the encoded amino acid, are regarded as evolving neutrally. However, if a certain region of a protein coding gene contains a functional nucleotide element (e.g. splicing signals), synonymous sites in the region may have selective pressure. The existence of such elements...

Throughout the C. elegans sequencing project Genefinder was the primary protein-coding gene prediction program. These initial predictions were manually reviewed by curators as part of a "first-pass annotation" and are actively curated by WormBase staff using a variety of data and information. In the WormBase data release WS133 there are 22,227 protein-coding gene, including 2,575 alternatively-...

Haplaxius crudus Van Duzee is a pest of various economically important palms due to its ability transmit lethal yellowing, fatal phytoplasma infection. It also the putative vector bronzing in Florida, another disease causing significant economic losses. To date, no mitochondrial genomes for species family Cixiidae are sequenced. In this study, complete genome H. was sequenced, assembled, and an...

Luciferases have been widely utilized as sensitive reporters to monitor gene expression and protein-protein interactions. Compared firefly luciferase (Fluc), a recently developed luciferase, Nanoluciferase (NanoLuc or Nluc), has several superior properties such smaller size stronger luminescence activity. We compared the reporter of Nluc Fluc in rice (Oryza sativa). In both plant-based two-hybr...

The inducible acetamidase of Mycobacterium smegmatis NCTC 8159 is expressed at high levels in the presence of a suitable inducer, such as acetamide. The gene and 1.5 kb of upstream sequence had previously been sequenced. A further 1.4 kb of upstream sequence has now been determined, containing an additional ORF on the opposite strand to the acetamidase gene. This ORF has significant homologies ...

Canine distemper virus (CDV; Paramyxoviridae, Morbillivirus) is the etiologic agent of a multisystemic infectious disease affecting all terrestrial carnivore families with high incidence and mortality in domestic dogs. Sequence analysis of the hemagglutinin (H) gene has been widely employed to characterize field strains, permitting the identification of nine CDV lineages worldwide. Recently, it...

Three cDNAs encoding the beta chain of Cap Z have been isolated from lambda gt11 chicken libraries screened with antibodies. The coding region, which is identical among the cDNAs, contains 831 basepairs encoding a protein with 277 amino acid residues and Mr = 31,352. The predicted protein sequence contains eight regions that match perfectly the NH2-terminal sequence of eight peptides isolated f...

dna coding for the core antigen from hepatitis b virus (hbcag) was amplified, cloned and propagated in e. coli. the core protein was expressed in e. coli and the product was readily detected by western blot. this protein can be used as a diagnostic material in serum screening tests. to increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
