The rRNA operon from Zea mays chloroplasts: nucleotide sequence of 23S rDNA and its homology with E.coli 23S rDNA.

The nucleotide sequence of 23S rDNA from Zea mays chloroplasts has been determined. Alignment with 23S rDNA from E.coli reveals 71 percent homology when maize 4.5S rDNA is included as an equivalent of the 3' end of E.coli 23S rDNA. Among the conserved sequences are sites for base modification. Chloramphenicol sensitivity and ribosomal subunit interaction. A proposal for the base pairs formed be...

Cotranscription and processing of 23S, 4.5S and 5S rRNA in chloroplasts from Zea mays.

The termini of rRNA processing intermediates and of mature rRNA species encoded by the 3' terminal region of 23S rDNA, by 4.5S rDNA, by the 5' terminal region of 5S rDNA and by the 23S/4.5S/5S intergenic regions from Zea mays chloroplast DNA were determined by using total RNA isolated from maize chloroplasts and 32P-labelled rDNA restriction fragments of these regions for nuclease S1 and primer...

Phylogeny of the Order Bacillales inferred from 3’ 16S rDNA and 5’ 16S-23S ITS nucleotide sequences

A short 220 bp sequence was used to study the taxonomic organization of the bacterial Order Bacillales. The nucleotide sequences of the 3’ end of the 16S rDNA and the 16S-23S Internal transcribed spacer (ITS) were determined for 32 Bacillales species and strains. The data for 40 additional Bacillales species and strains were retrieved directly from Genbank. Together, these 72 Bacillales species...

Phylogenetic analysis of phytoplasmas based on sequences derived from the secA and 23S rDNA genes

Phylogenetic analysis of a 500 bp fragment of the secA gene has been performed on 35 phytoplasma isolates representing 10 of the 16S rDNA groups. The lineages obtained coincide with those delineated by 16S rDNA phylogenetic analysis but much greater genetic variability was evident. In addition, phylogenetic analysis based on part of the 23S rDNA gene combined with T-RFLP (terminal restriction f...

Identification of acetic acid bacteria by RFLP of PCR-amplified 16S rDNA and 16S-23S rDNA intergenic spacer.

DNA corresponding to 16S rDNA and the 165-23S rDNA intergenic spacer (ITS) from 22 reference strains of acetic acid bacteria, representing the diversity of the family Acetobacteraceae, and 24 indigenous acetic acid bacteria isolated from wine fermentations were analysed by PCR-RFLP. Frateuria aurantia LMG 1558T and Escherichia coli ATCC 11775T were included as outgroups. PCR-amplified products ...
