摘要：

The nucleotide sequence of a 4.2-kb EcoRI fragment from the intergenic region between the genes for 25S and 18S ribosomal RNA of Pharbitis nil Choisy was determined. The region contained a unique repetitive family of DNA sequences, called the RsaI family, composed of 32-bp units. The 32-bp unit was tandemly repeated in the intergenic region, and four subfamilies of repeating units were clustered as discrete blocks. The RsaI family of repeats was shown to be specific to the genus Pharbitis by Southern blot hybridization.
