Abstract
16S/23S intergenic spacer regions from the rRNA operons of two strains of ''Candidatus Liberobacter asiaticum'' and one strain of ''Candidat us Liberobacter africanum'' were cloned and sequenced. The intergenic spacers of the two ''Candidatus L. asiaticum'' strains studied are ide ntical and contain the genes for isoleucine tRNA (tRNA(Ile)) and alani ne tRNA (tRNA(Ala)) separated by 11 nucleotides. The intergenic spacer of the ''Candidatatus L. africanum'' strain contains only one tRNA ge ne (tRNA(Ala)). The level of homology between the intergenic spacers o f the two liberobacter species is 79.46%. Ribosomal operons with 16S/2 3S spacer regions other than those studied might be present in the two ''Candidatus Liberobacter'' species.
