Abstract Pervasive transcription of eukaryotic genomes results in expression long non-coding RNAs (lncRNAs) most which are poorly conserved evolution and appear to be non-functional. However, some lncRNAs have been shown perform specific functions, particular, regulation. Thousands small open reading frames (smORFs, <100 codons) located on potentially might translated into peptides or microproteins. We report a comprehensive analysis the conservation evolutionary trajectories...
Plant-virus interactions are greatly influenced by environmental factors such as temperatures. In virus-infected plants, enhanced temperature is frequently associated with more severe symptoms and higher virus content. However, the mechanisms involved in controlling regulation of plant-virus poorly characterised. To elucidate these further, we analysed responses potato plants cv Chicago to infection Y (PVY) at normal (22 °C) elevated (28 °C), latter which known significantly increase plant...
Nonsense-mediated mRNA decay (NMD) is a system that controls the quality of transcripts in eukaryotes by degradation aberrant pioneer round translation. In mammals, NMD targets one-third mutated, disease-causing mRNAs and ∼10% unmutated mRNAs, facilitating appropriate cellular responses to environmental changes [1]. plants, plays an important role development regulating abiotic biotic stress [2]. The with premature termination codons (PTCs), upstream ORFs or long 3′-UTRs can be targeted NMD....
Small open reading frames (<100 codons) that are located on long noncoding RNAs (lncRNAs) can encode functional microproteins. These microproteins shown to play important roles in different cellular processes, such as cell proliferation, development and disease response [1], [2], [3], [4], [5], [6]. However, there only a few known lncRNA-encoded plants. One microprotein was named PSEP3, identified the moss Physcomitrium patens by mass-spectrometry analysis. 57-aa PSEP3 contains Low...
Abstract Abundance of polyploidy varies across lineages, evolutionary time and geography, suggesting both genetics environment play a role in polyploid persistence. Arabidopsis lyrata appears to be the most polyploidy-rich species-complex genus, with multiple origins autotetraploidy. This is revealed by genomic data from over 400 samples Eurasia. We found 30 previously undescribed autotetraploid populations Siberia minimum two separate origins, independent those reported Central Europe. The...
Polyploidization or whole-genome duplication (WGD), followed by genome downsizing is a recurring evolutionary cycle with significant impact on structure. Polyploidy originates from cell error and in species without dedicated germline, mitotic as well meiotic errors can be stably inherited. After the origin, polyploids face immediate challenges, particularly need to adapt machinery prevent improper chromosome pairing segregation, such multivalent formation. Over timescales, surviving undergo...
Abstract Recent evidence shows that small open reading frame (smORF; <100 codons)-encoded peptides (SEPs) containing transmembrane domains are preadapted to be progenitors of novel functional genes. A dozen such SEPs translated from long non-coding RNAs (lncRNAs) already functionally characterised in animals. However, plant lncRNA-smORF-coded not yet described. Here, we report detailed characterization a 41-aa peptide encoded by lncRNA-smORFs the moss Physcomitrium patens, which was named...
Nonsense-mediated RNA decay (NMD) mechanism controls the quality of eukaryotic mRNAs by degradation aberrant transcripts with a premature stop codon (PTC) in pioneer round translation. Besides transcripts, up to 10% normal mRNA can be regulated NMD. As NMD machinery is associated translation, this system takes part proteome formation cells [1,2]. However, no proteomic datasets plants deficient are currently available. Here, we provide an isobaric tag for relative and absolute quantitation...
