Abstract
We isolated and cloned DNA fragments that exist as inverted-repeat structures in the genome of Pharbitis nil. The method used exploited the fact that if inverted repeat DNA is present in the DNA fragment, intramolecular double-stranded structures can be partly formed within single-stranded DNA molecules after denaturation and rapid renaturation of the fragment. The rapidly renaturing DNA fragments (termed snap-back DNA) were isolated by hybroxylapatite column chromatography and treatment with mungbean nuclease and were cloned into the pUC9 vector. Four snap-back DNA members out of thousands of independent clones obtained were characterized with respect to the reiteration frequency and the nucleotide sequences. When used as probes in Southern hybridization experiments, some of the members identified restriction fragment length polymorphism among the cultivars, suggesting that these sequences might be fluid in the genome. One of the four clones has regions of nucleotide sequence homology to those of inverted-repeat regions in the transposon Taml of Antirrhinum majus.
