title: Genome structure of a new avian sarcoma virus PR2257 determined by restriction analysis.
abstract: The genome structure of a new avian src-containing acute transforming virus, designated PR2257, was studied by restriction analysis. PR2257 was isolated from a sarcoma grown in a 155-day-old chick inoculated intraembryonally with a transformation-defective mutant of daPR-C retaining no src sequences. The 4.4-kb genome of PR2257 consists of the following regions: 5' LTR--spliced version of chicken c-src--incomplete env gene--3' LTR. This structure clearly indicates that PR2257 was generated by recombination between a td daPR-C and chicken c-src.
