  • New approaches to plant disease control are important for pathogens that are difficult to control by existing methods. Here, the authors report a potential strategy to combat plant viruses by cytosolic expressed protein-only RNase P and show its ability for in vitro cleavage of tRNA-like structures existing in many plant viruses.

  • This study shows that the tRNA-modifying enzymes TRM1A/TRM1B are essential to attain the steady-state pool of tRNAs and reveals how they functionally cooperate with RNase P in vivo for the early steps of tRNA biogenesis in Arabidopsis.
