The UvrB gene in every house finch MG strain sampled contains a mutation that truncates the final 3 amino acids of the protein, and this mutation is also present in the closely related TK_2001. The DNA encoding the C-terminal of this amino acid contains a 2 time repeat of the sequence “TAAG” and this mutation introduced one additional repeat of this sequence as a 4 bp insertion. The effect of t...

Caseous lymphadenitis (CLA) is an acute, pyogenic, and contagious disease of goat that imposes considerable economic losses for farmers, and it is caused by Corynebacterium pseudotuberculosis Herein, we introduce the genome sequencing of C. pseudotuberculosis strain KM01, isolated from an abscess of a Saanen goat from Kunming, China. The genome contains 2,198 genes, the total length of the gene...

Tc3 is a member of the Tc1/mariner family of transposable elements. All these elements have terminal inverted repeats, encode related transposases and insert exclusively into TA dinucleotides. We have studied the DNA binding properties of Tc3 transposase and found that an N-terminal domain of 65 amino acids binds specifically to two regions within the 462 bp Tc3 inverted repeat; one region is l...

Data from 1238 fishes from 19 sturgeon species and 1 paddlefish were used to analyze heteroplasmy in sturgeon. Lengths of central repeat units ranged from 74 to 83 bp among sturgeon species. No repeat sequence was found in the paddlefish, Polyodon spathula. A general feature of the repeat units was the presence of termination associated sequence (TAS) motifs. About 50% of 138 interspecific muta...

There is considerable evidence to support a role of dopamine-related genes in the molecular aetiology of attention-deficit hyperactivity disorder (ADHD). A 48 bp repeat in exon three of the dopamine D4 receptor gene has been widely studied in clinical ADHD samples, and a meta-analysis of published studies suggests it is associated with ADHD. A number of other polymorphisms across this gene have...

A novel filamentous virus, AFV2, from the hyperthermophilic archaeal genus Acidianus shows structural similarity to lipothrixviruses but differs from them in its unusual terminal and core structures. The double-stranded DNA genome contains 31,787 bp and carries eight open reading frames homologous to those of other lipothrixviruses, a single tRNA(Lys) gene containing a 12-bp archaeal intron, an...

Swertia mussotii is an important medicinal plant that has great economic and medicinal value and is found on the Qinghai Tibetan Plateau. The complete chloroplast (cp) genome of S. mussotii is 153,431 bp in size, with a pair of inverted repeat (IR) regions of 25,761 bp each that separate an large single-copy (LSC) region of 83,567 bp and an a small single-copy (SSC) region of 18,342 bp. The S. ...

We analyzed 15 recombinant DNA clones of the unintegrated closed circular DNA intermediate of the BALB/c endogenous ecotropic murine leukemia virus WN1802N. Thirteen of these clones had an insert which corresponded to the complete murine leukemia virus genome. Of these, six contained a single long terminal repeat (LTR) and seven contained two LTRs. The viral genomes in nine clones had an LTR of...

At either end of the nopaline Ti-plasmid T-region resides a copy of a 25 bp repeated element. The normal T-DNA endpoint is 1 bp internal of the right copy, with the transcription initiation site of the nopaline synthase (nos) gene being approximately 300 bp away in the same direction. Here we describe results which demonstrate that deletion of any combination of sequences between the nos initia...

We have identified in the human genome two families of mobile elements possessing the sequence characteristics of transposons that move directly from DNA to DNA rather than requiring the reverse transcription of an RNA intermediate. One type of element is closely related to the autonomous transposable element, mariner, and comprises a coding region for a transposase protein flanked by short ter...
