Organization of rRNA genes in Mycobacterium bovis BCG [PDF]

Journal of Bacteriology, 1987
The number of rRNA genes in Mycobacterium bovis BCG was examined by Southern hybridization of end-labeled 5S, 16S, and 23S rRNAs with BamHI, PstI, and SalI digests of M. bovis BCG DNA. Each RNA probe gave only one radioactive band with three kinds of DNA digest. These results suggest that M.

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Groundtruthing next-gen sequencing for microbial ecology-biases and errors in community structure estimates from PCR amplicon pyrosequencing [PDF]

, 2012
Analysis of microbial communities by high-throughput pyrosequencing of SSU rRNA gene PCR amplicons has transformed microbial ecology research and led to the observation that many communities contain a diverse assortment of rare taxa-a phenomenon termed ...

Isolation of Partial Housekeeping Genes on Tuntun Angin (Elaeocarpus floribundu)

Biosaintifika: Journal of Biology & Biology Education, 2019
Some genes like 18S rRNA, 26S rRNA, elongation factor 1-alpha (EF1a), and beta-tubulin (TUB) are members of housekeeping genes group that are commonly used as internal control in gene expression study.

Regulation of Arabidopsis thaliana 5S rRNA Genes [PDF]

Plant and Cell Physiology, 2007
The Arabidopsis thaliana genome comprises around 1,000 copies of 5S rRNA genes encoding both major and minor 5S rRNAs. In mature wild-type leaves, the minor 5S rRNA genes are silent. Using different mutants of DNA methyltransferases (met1, cmt3 and met1 cmt3), components of the RNAi pathway (ago4) or post-translational histone modifier (hda6/sil1), we ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Rlp7p is associated with 60S preribosomes, restricted to the granular component of the nucleolus, and required for pre-rRNA processing [PDF]

, 2002
Many analyses have examined subnucleolar structures in eukaryotic cells, but the relationship between morphological structures, pre-rRNA processing, and ribosomal particle assembly has remained unclear.

Characterization of spiny lobsters from Bangladesh waters using morphology, COI and 16S rRNA sequences

Heliyon, 2022
This study aims to taxonomically identify and characterise the phylogenetic relationships of spiny lobsters based on mitochondrial cytochrome c oxidase I (COI) and 16S rRNA genes from Bangladesh waters.

A single rRNA gene region in Bradyrhizobium japonicum [PDF]

Journal of Bacteriology, 1995
Bradyrhizobium japonicum contains only a single rRNA (rrn) gene region, despite its comparatively large genome size of 8,700 kb. The nucleotide sequence revealed an organization of rRNA and tRNA genes that is frequently found in bacteria: 5'-rrs (16S rRNA)-ileT (tRNA(Ile))-alaT (tRNA(Ala))-rrl (23S rRNA)-rrf (5S rRNA)-3'.
