The Lactococcus lactis temperate bacteriophage BK5-T is one of twelve type phages that define L. lactis phage species. This paper describes the nucleotide sequence and analysis of a 21-kbp region of the BK5-T genome and completes the nucleotide sequence of the genome of this phage. The 40,003-nucleotide linear genome encodes 63 open reading frames. Sequence runoff experiments showed that the co...

Actinobacillus pleuropneumoniae serotype 7 strains are shown to spontaneously lose cytolytic activity with a frequency of approximately 10(-4). The phenotypic change is associated with the loss of approximately 8.5 kbp of chromosomal DNA. A genomic fragment encoding the cytolysin and its flanking sequences was cloned and characterized. Also, the corresponding truncated fragment was cloned from ...

Alcelaphine herpesvirus type 1 (AHV-1) is a causative agent of the fatal lymphoproliferative disease malignant catarrhal fever in deer and cattle. The genomes of the attenuated WC11 isolate and the virulent C500 isolate have been studied. The genome of WC11 comprises a region of unique DNA of approximately 130 kbp, which has a G + C content of 50%, and approximately 30 kbp of additional tandem ...

The complete 17,009-bp mitochondrial genome of the domestic cat, Felis catus, has been sequenced and conforms largely to the typical organization of previously characterized mammalian mtDNAs. Codon usage and base composition also followed canonical vertebrate patterns, except for an unusual ATC (non-AUG) codon initiating the NADH dehydrogenase subunit 2 (ND2) gene. Two distinct repetitive motif...

The genome size in eukaryotes does not correlate well with the number of genes they contain. We can observe this so-called C-value paradox in amphibian species. By analyzing an amphibian genome we asked how repetitive DNA can impact genome size and architecture. We describe here our discovery of a Tc1/mariner miniature inverted-repeat transposon family present in Xenopus frogs. These transposon...

Physalis macrophysa (PMA) and ixocarpa (PIX) have significant economic, medicinal, ornamental value are often used in the fields of edible fruits, medicinal herbs, plants. In present study, we obtained complete chloroplast (cp) genome sequences PMA PIX, compared to cp 10 species, constructed phylogenetic tree among tribe Physaleae. The results showed that genomes PIX consisted a large single co...

Molecular analysis of a mutant wary allele, wx-mum5 (Don that of Mul (67%), but significantly higher than the G/C content Robertson, unpublished), revealed the presence of a previously of the entire maize genome, estimated to be 49.5% G/C (2). unidentified maize Mutator element (Mu8) within the tenth exon of the waxy gene. The element is 1410 base pairs (bp) long and is flanked by a nine bp dir...

The dimeric AraC protein of Escherichia coli binds specifically to DNA sequences upstream of promoters whose transcription is regulated by arabinose. Here we show with affinity measurements, DNase footprinting, dimethyl sulfate premethylation interference and dimethyl sulfate footprinting studies that AraC protein can recognize paired half-sites in direct repeat orientation or inverted repeat o...

We report the complete genome sequence of Helicobacter cinaedi strain PAGU611, isolated in a case of human bacteremia. The PAGU611 genome comprises a 2,078,348-bp chromosome and a 23,054-bp plasmid. The chromosome contains a unique genomic island, encoding a type VI secretion system and clustered regularly interspaced short palindromic repeat (CRISPR) loci.

A herpesvirus genome was sequenced directly from a biopsy specimen of a rectal lesion from a female common bottlenose dolphin. This genome sequence comprises a unique region (161,235 bp) flanked by multiple copies of a terminal repeat (4,431 bp) and contains 72 putative genes. The virus was named common bottlenose dolphin gammaherpesvirus 1.
