Structure and evolution of the intergenic region in a ribosomal DNA repeat unit of wheat.

Journal article

The complete nucleotide sequence of the intergenic region between the 25 S and 18 S wheat ribosomal RNA genes has been determined from a 4.6 kb EcoRI-BamHI fragment (1 kb = 10(3) bases or base-pairs) subcloned from the plasmid pTa71. Within this subclone the intergenic DNA is flanked by the 3' end of the 25 S and the 5' end of the 18 S ribosomal RNA sequences. Four repeat families are present within the intergenic region. The major repeat family A, consists of 12 direct repeat units of 135 or...
