The nucleotide sequence has been determined for a 664-base pair region of maize (Zea mays L.) mtDNA which contains the 3' end of the 18S rRNA gene, the 5S rRNA gene, and an intergenic region of 108 base pairs. Specific regions of the 18S rRNA gene show striking homology with the corresponding gene in Escherichia coli.

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. a polymerase chain reaction (pcr) assay was developed using primers derived from conserved part of 16s-23s rrna gene. the pcr amplified a fragment size of 0.7 kb using dna from nine avian p. multocida  isolates...

The lactic acid bacteria (LAB) are an industrially important group of probiotic organisms that play an important role in human health by inhibiting harmful and pathogen bacteria growth, boosting immune function, and increasing resistance to infection.  This study aimed to isolate, identify, and biologically characterize probiotic LAB strains from Iranian traditional dairy products. A ...

Almost complete 23S rRNA gene sequences were obtained from 13 planctomycete strains, the fimbriated, prosthecate bacterium Verrucomicrobium spinosum and two strains of the genus Prosthecobacter. The 23S rRNA genes were amplified by the PCR, using modified primers. The majority of the planctomycete strains investigated were shown to have 23S rRNA genes that were not linked to the 16S rRNA genes....

Molecular investigation of two Nocardia patient isolates showed unusual restriction fragment length polymorphism patterns with restriction endonuclease assays (REA) using an amplified portion of the 16S rRNA gene. Patterns typical of Nocardia nova were obtained with REA of an amplified portion of the 65-kDa heat shock protein gene. Subsequent sequence analysis of the 16S rRNA gene regions of th...

The complete nucleotide sequences of the 5.8S and 26S rRNA genes of Physarum polycephalum and the transcribed spacer between them were determined. Comparison of the sequences with those of the Escherichia coli 23S rRNA and yeast 26S rRNA genes showed that there are 16 highly homologous regions in the sequences of Physarum and E. coli and that eukaryotes have some eukaryote-specific extra sequen...

conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...

Although 16S rRNA gene sequence analysis is employed most often for the definitive identification of Nocardia species, alternate molecular methods and polymorphisms in other gene targets have also enabled species determinations. We evaluated a combined Nocardia PCR-based reverse line blot (RLB) hybridization assay based on 16S and 16S-23S rRNA gene spacer region polymorphisms to identify 12 Ame...
