Koch (Umbelliferae) Genus. International Journal of Botany, 2: 17-22.18119700https://doi.org/10.3923/ijb.2006.17.22https://hdl.handle.net/20.500.12587/1889To identify important structural features in the intergenic sequences of ribosomal DNAs, the nucleotide sequence of the 18-28S rRNA intergene region was determined in Ferulago genus. During the pre-rRNA processing pathway the corrected and efficient excision of the internal transcribed spacers (ITS1 and ITS2) is a crucial step for the biogenesis of a active ribosomal subunits. The recognition elements located in ITS were conserved among Ferulago species. While a striking sequence homology was observed in the mature ribosomal sequences, the two internal transcribed spacer regions were found to be G+C rich. Some variations among ITS sequences of this genus is found among Ferulago species. © 2006 Asian Network for Scientific Information.eninfo:eu-repo/semantics/openAccessFerulagoITS1ITS2PolymorphismrDNARNA processingArticle21172210.3923/ijb.2006.17.222-s2.0-33747164214N/A
