Abstract
- In the intergenic spacer (IGS) of rDNA of diploid wheats Triticum urartu, T. boeoticum, and T. monococcum, the uncommon motives adjacent to the site of transcription initiation (TIS) are revealed. They are located in the region from -6 to +1 relative to the putative TIS and are not encountered in cereals studied earlier. In T. urartu and T. boeoticum, the motif TACTATG has been revealed, in T. monococcum--TATTATG, while diploid Aegilops speltoides has the motif TATAGTA, typical of the remaining cereal species. The TIS-surrounding rDNA IGS region of diploid wheats was compared to the correspondent known rDNA IGS regions of different plant and animal species.
