    Structural elucidation of a novel mechanism for the bacteriophage-based inhibition of the RNA degradosome

    An Van den Bossche et al.
    A bacteriophage remodels the RNA metabolism machinery of a bacterial host to sequentially clear host transcripts and then stabilize the viral RNA.

    Spatial organization shapes the turnover of a bacterial transcriptome

    Jeffrey R Moffitt et al.
    Transcriptome-scale RNA imaging and lifetime measurements reveal that the E. coli transcriptome is spatially organized and that this organization modulates the post-transcriptional fate of bacterial mRNAs.

    Regulation of rice root development by a retrotransposon acting as a microRNA sponge

    Jungnam Cho, Jerzy Paszkowski
    Retrotransposon-derived messenger RNA plays a critical role in rice root development via sequestration of miR171, which suggests a novel trans-acting regulation by transposable elements.

    RNA chaperones buffer deleterious mutations in E. coli

    Marina Rudan et al.
    The overexpression of RNA chaperones, including several DEAD box RNA helicases, enhances the fitness of mutationally compromised E. coli strains.

    A type III-A CRISPR-Cas system employs degradosome nucleases to ensure robust immunity

    Lucy Chou-Zheng, Asma Hatoum-Aslan
    Degradosome-associated nucleases PNPase and RNase J2 are required for type III CRISPR immunity against diverse nucleic acid invaders originating from plasmid and phage.

    Normal mitochondrial function in Saccharomyces cerevisiae has become dependent on inefficient splicing

    Marina Rudan et al.
    Removal of mitochondrial introns (Saccharomyces cerevisiae) from their host genes leads to detrimental increase in their transcript levels.
