5S-rRNA genes in rice embryos [PDF]
Plant Molecular Biology, 1987 The 5S-rRNA from the ungerminated and 48-h-germinated rice embryos differs from the wheat, rye and maize by two nucleotides. The 48-h-germinated embryos contain another species of 5S-rRNA which differs by 3 nucleotides from the ungerminated embryos, thereby showing the expression of two 5S-rRNA genes during germination. The 5S-rRNA genes are present in

Alternating polarity in rRNA genes
Cell Biology International Reports, 1978Spread nucleolar material from A. exigua exhibits an unusual arrangement of rDNA cistrons. The cistrons form head-to-head "diamond-shaped" doublets with a short spacer separating the members of the doublet. Single cistrons are usually terminal and arrange tail-to-tail with the adjacent doublet, suggesting the possibility of a repeating unit with a tail-

Current Genetics, 1987
A 243 bp intron was found within the 23S rRNA gene of the unicellular green alga Chlorella ellipsoidea. This intron is A+T-rich (63.7%) compared with the 23S rRNA (50.5%) and is located in domain II of the 23S rRNA. In contrast to rRNA introns so far known, this intron is considerably small and does not possess features of group I introns in spite of ...

16S rRNA Gene Analysis with QIIME2
2018Microbial marker-gene sequence data can be used to generate comprehensive taxonomic profiles of the microorganisms present in a given community and for other community diversity analyses. The process of going from raw gene sequences to taxonomic profiles or diversity measures involves a series of data transformations performed by numerous computational

Chromosoma, 1978
DNA samples from various higher plants (Phaseolus aureus, Glycine max, Matthiola incana, Brassica pekinensis, Cucumis melo) were centrifuged in actinomycin-caesium chloride gradients and the genes coding for the ribosomal RNAs were detected by hybridisation with tritium labelled 5S and 25S+18S rRNA, respectively.

RFLPs of the rRNA genes in the genusPhaseolus
Genetic Resources and Crop Evolution, 1995Restriction fragment length polymorphisms of the rRNA genes were investigated among 20 genotypes ofP. vulgaris, P. coccineus, P. polyanthus, P. microcarpus, P. glabellus, P. acutifolius, P. maculatus, P. oligospermus andP. lunatus. Detection of the polymorphisms was performed nonradioactively with a digoxigenin-labeled rDNA probe.

In order to study the organization of the ribosomal RNA genes of Mycoplasma hyopneumoniae the rRNA genes were cloned in phage vectors lambda EMBL3 and lambda EMBL4. By subcloning the restriction fragments into various plasmids and analysing the resulting clones by Southern and Northern blot hybridization, a restriction map of the rRNA genes was ...

Transfer RNA genes between 16S and 23S rRNA genes in rRNA transcription units of E. Coli
Cell, 1976We have identified genes for tRNAGLU/2 on the transducing phages o80d3ilvsu7+ (see Ohtsubo et al., 1974) and lambdarifd18 (Kirschbaum and Konrad, 1973), and a gene for tRNAlle/1 on the transducing phage o80rifr (Konrad, Kirschbaum, and Austin, 1973). All these phages have previously been shown to carry genes for rRNA (Ohtsubo et al., 1974; Lindahl et ...
