Fig. 2

Organization and sequence similarity of the intergenic spacer (IGS) of 45S rDNA of Atropa belladonna (Abel - clone Ab-IGS-1S; Genbank Acc. No KF492694), Solanum bulbocastanum (Sblb – [27]) and Nicotiana tomentosiformis (Ntom – [19]). Percents of similarity for different structural regions (SR I – SR VI) of IGS are given. TIS: transcription initiation site; TTS: putative transcription termination site. Localization of restriction endonucleases recognition sites (B: Bam HI, EI: Eco RI, EV: Eco RV, S: Sph I, Xb: Xba I, Xh: Xho I) used for IGS mapping of A. belladonna rDNA is shown
