RNA silencing in plant symbiotic bacteria: Insights from a protein-centric view

Figures & data

Figure 1. SmYbeY influences turnover of bulk and sRNA-regulated mRNAs. Shown are enrichment patterns of putative SmYbeY mRNA substrates in SmHfq CoIP-RNA.²⁷ The vertical axis indicate fold enrichment with respect to a control CoIP-RNA. Relevant genomic information for each mRNA is provided in the schematics below the plots. Numbering denotes coordinates in the S. meliloti Rm1021 genome. SmYbeY-mediated silencing of nifA and prbA mRNAs is likely triggered by base-pairing with the trans-sRNA AbcR2 and the asRNA265, respectively. See text for further details.
