Nucleotide sequence of the potato rDNA intergenic spacer.
The large intergenic spacer (IGS) of potato rDNA was sequenced and compared to the IGS sequence of tomato. Both spacers exhibit similar length and architecture. Absence of repeated elements down-stream of the putative transcription initiation site (TIS) in potato is compensated by the larger number of subrepeats upstream of the TIS. Especially high level of similarity (86% and 86.5%, respectively) is found in the AT-rich domain containing the TIS and the region approx. 800 bp upstream of the 18S rRNA gene.
