Sequence organization of porcine DNA

Sequence of porcine circovirus DNA: affinities with plant circoviruses.

The complete nucleotide sequence (1759 nt) of the ssDNA genome of porcine circovirus (PCV) was determined from a cloned dsDNA replicative form isolated from PCV-infected cells. Sequence analysis detected no significant nucleic acid or protein similarity with another animal circovirus, chicken anaemia virus (CAV) but, surprisingly, the highest protein similarity was obtained between the product ...

Sequence organization of feline leukemia virus DNA in infected cells.

A restriction site map has been deduced of unintegrated and integrated FeLV viral DNA found in human RD cells after experimental infection with the Gardner-Arnstein strain of FeLV. Restriction fragments were ordered by single and double enzyme digests followed by Southern transfer (1) and hybridization with 32P-labeled viral cDNA probes. The restriction map was oriented with respect to the 5' a...

A new moderately repetitive DNA sequence family of novel organization.

In cloning adenovirus homologous sequences, from a human cosmid library, we identified a moderately repetitive DNA sequence family consisting of tandem arrays of 2.5 kb members. A member was sequenced and several non-adjacent, 15-20 bp G-C rich segments with homology to the left side of adenovirus were discovered. The copy number of 400 members is highly conserved among humans. Southern blots o...

Pilus genes of Neisseria gonorrheae: chromosomal organization and DNA sequence.

We have mapped two regions of the Neisseria gonorrheae genome, pilE1 and pilE2, which are involved in pilus expression. When the cells are in the piliated P+ state, these two loci carry sequences necessary for pilin production. A silent locus, pilS1, also maps near pilE1 and pilE2. pilS1 contains structural gene information but lacks pilus promoter sequences. The pilus gene sequences in pilE1 a...
