Abstract: The intergenic spacer (IGS) region of rDNA in
Olea europaea is 5,629 bp long and it can be subdivided,
on the basis of the different features, into six regions; two
of them, located upstream and downstream of the putative
transcription initiation site (TIS), respectively, contain
prominent and unrelated subrepeats (s.r.). The upstream s.r.
are 75–86 bp in length and the downstream ones are about
160 bp in length. The first type is represented by a high number
(36) of iterations, which share a mutual similarity of 82.5%. A
single sequence (TATTATAGGGGGGAGG) is found, which
fits the reported TIS of plants and the position +1 would
correspond to the adenine at position 3,622 after the 3′ end of
25 S ribosomal RNA (rDNA) genes. Moreover, in Olea IGS
region some unusual features are observed and discussed in
relation to analogous data present in the literature.
