The structure of the maize ribosomal DNA spacer region.

M D McMullen, B Hunter, R L Phillips, I Rubenstein.

Abstract

A combination of a single stranded plasmid vector and ordered deletions were used to determine the complete nucleotide sequence of a rDNA spacer region isolated from the DNA of maize Black Mexican Sweet suspension cells. The sequence reveals the presence of ten "200 base" subrepeats within the maize rDNA spacer region. By S1 protection experiments we have tentatively determined that the start of maize rRNA transcription is 144 bases 3' of the end of the last spacer subrepeat. We propose that the spacer subrepeats may have an important role in regulating maize rRNA transcription.
