Environmental Shaping of Ribosomal RNA Nucleotide Composition

Microbial Ecology, 2008
Ribosomal RNA (rRNA) is one of the most important macromolecules in the cell. It is well established that high-temperature environmental conditions destabilize rRNA, leading to a selection for G+C-rich stabilizing structures. Our knowledge about the nucleotide composition effect of other environmental conditions, however, is limited.

Absence of human astrovirus RNA in sewage and environmental samples

Journal of Applied Microbiology, 1999
Over a period of several weeks during the summer of 1996, samples of sewage, sea water, river water, sand and silt were collected from a sewage works at Weston-super-Mare, England and from coastal areas nearby. A sensitive reverse-transcriptase polymerase chain reaction (RT-PCR) was used to search for human astrovirus (HAstV) RNA in concentrates of the

RNA silencing: Mechanism, biology and responses to environmental stress

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2011
Much early work on environmental stress, including ionizing radiation and environmental toxins, emphasised their action on DNA and subsequent mutagenesis in long term effects including germ cell mutagenesis, carcinogenesis and trans-generational effect.

Environmental DNA and RNA Metabarcoding

Environmental DNA (eDNA) and RNA (eRNA) technologies, when integrated with metabarcoding, have emerged as significant instruments in cancer research particularly in exposomics and environmental carcinogenesis. These approaches facilitate the identification and monitoring of genetic material from many environmental sources, yielding insights into the ...

Circular RNAs: A Potential Regulator in Environmental Chemical Carcinogenesis

Chemical Research in Toxicology
Circular RNA (circRNA), a class of evolutionarily conserved, structurally stable, and tissue-specifically expressed noncoding RNA, is increasingly recognized as a key regulator of diverse biological processes and disease pathogenesis, including cancer.

Commentary: Environmental RNA and the assessment of organismal function in the field

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology
Environmental RNA (eRNA) is an emerging technique with significant potential for the assessment of organismal function in field settings. It has the advantage of being non-invasive, facilitating insight into the physiological status of an organism without complications associated with processes such as capture, handling, and transportation from the ...

Functional implications of ribosomal RNA methylation in response to environmental stress

Critical Reviews in Biochemistry and Molecular Biology, 2013
The study of post-transcriptional RNA modifications has long been focused on the roles these chemical modifications play in maintaining ribosomal function. The field of ribosomal RNA modification has reached a milestone in recent years with the confirmation of the final unknown ribosomal RNA methyltransferase in Escherichia coli in 2012.

RNA 5-Methylcytosine Controls Plant Development and Environmental Adaptation

Trends in Plant Science, 2020
Despite increasing understanding of 5-methylcytosine (m5C) on RNAs in mammals, the function of m5C in plants remains obscure. A dynamic function of m5C in plant development and stress adaptation had been suggested, and Tang et al. have now uncovered a role for RNA m5C methyltransferase in rice adaptation to high temperature.

Uptake and Reaction of C. elegans to Environmental RNAs

2016
Relation between animals and bacteria is just like marriage made by evolution. For Caenorhabditis elegans, bacteria are part of their food as well as the environments. In recent decades, C. elegans has been extensively used as a model organism for studying host–microbiota interactions. As dsRNAs expressed in E. coli , which is the laboratory food of C.

Resistance to environmental stress requires the RNA chaperones CspC and CspE

Environmental Microbiology Reports, 2012
Summary Stress response is essential for adaptation and for survival during environmental changes. A major factor in these responses is RpoS (σS), the master regulator of stationary phase and of the general stress response in Escherichia coli.
