Abstract

A highly conserved sequence was found in rRNA gene internal transcribed spacer 1 (ITS1) among flowering plant species. The sequence, GGCRY-(4 to 7 n)-GYGYCAAGGAA (where Y=C or T; R=G or A) is located in the central region of ITS1, and is present in published sequences from a wide range of flowering plants. The rest of ITS1 is highly variable in sequence. Therefore, the conserved motif within ITS1 may have a key function in the processing of rRNA gene transcripts. Furthermore, identification of such a conserved motif will help facilitate alignment of sequences for phylogenetic analysis.
