Higher-order organisation of extremely amplified, potentially functional and massively methylated 5S rDNA in European pikes (Esox sp.)

BMC Genomics, 2017
Background Pikes represent an important genus (Esox) harbouring a pre-duplication karyotype (2n = 2x = 50) of economically important salmonid pseudopolyploids.

Nascent polypeptide chains exit the ribosome in the same relative position in both eucaryotes and procaryotes. [PDF]

, 1983
We located the polypeptide nascent chain as it leaves cytoplasmic ribosomes from the plant Lemna gibba by immune electron microscopy using antibodies against the small subunit of the enzyme ribulose-1,5-bisphosphate carboxylase.

The linked units of 5S rDNA and U1 snDNA of razor shells (Mollusca: Bivalvia: Pharidae) [PDF]

, 2011
[Abstract] The linkage between 5S ribosomal DNA and other multigene families has been detected in many eukaryote lineages, but whether it provides any selective advantage remains unclear.

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Resurrection of an ancestral 5S rRNA

BMC Evolutionary Biology, 2011
Background In addition to providing phylogenetic relationships, tree making procedures such as parsimony and maximum likelihood can make specific predictions of actual historical sequences.

DNA-methylation dependent regulation of embryo-specific 5S ribosomal DNA cluster transcription in adult tissues of sea urchin Paracentrotus lividus [PDF]

, 2013
We have previously reported a molecular and cytogenetic characterization of three different 5S rDNA clusters in the sea urchin Paracentrotus lividus and recently, demonstrated the presence of high heterogeneity in functional 5S rRNA.

Chromosome‐Scale Haplotype Genome Assemblies for the Australian Mango ‘Kensington Pride’ and a Wild Relative, Mangifera laurina, Provide Insights Into Anthracnose‐Resistance and Volatile Compound Biosynthesis Genes

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3172-3188, May 2026.
ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...

Stability and Expression of Selected miRNAs, circRNAs, and rRNAs in Swiss Albino Mice Tissues to Preditc Port-Mortem Interval

Brazilian Journal of Forensic Sciences, Medical Law and Bioethics
In forensics, post-mortem interval (PMI) estimation is essential. Researchers have devised various approaches to accurately determine PMI, consequently, ribonucleic acid (RNA) molecules could be useful PMI estimation tool.

Polytene chromosomes as indicators of phylogeny in several species groups of Drosophila. [PDF]

, 2001
BackgroundPolytene chromosome banding patterns have long been used by Drosophila evolutionists to infer degree of relatedness among taxa. Recently, nucleotide sequences have preempted this traditional method.

Fully Tunable Phosphorylation of RPS6A Ensures the Successful Development of Arabidopsis Seedlings

Plant, Cell &Environment, Volume 49, Issue 5, Page 2783-2794, May 2026.
ABSTRACT Light enhances protein translation, enabling young seedlings to rapidly and timely acquire photosynthetic capacities. Sequential phosphorylation of ribosomal protein S6 (RPS6) was implicated in the light‐enhanced translation; however, the exact phosphorylation sites and the biological relevance of RPS6 multi‐phosphorylation in seedling ...
