RNA trafficking

 

RNA trafficking and localization are fundamental processes during development and signaling across phyla. Plants support the intercellular transport of RNA molecules including messenger RNAs and small RNAs through plasmodesmata (PD), with fundamental implications in cell-to-cell and long distance signaling during development, responses to environmental stresses and defense. RNA viruses exploit these RNA transport mechanisms for the distribution of their genomes and establishment of systemic infections. To understand these mechanisms, we use Tobacco mosaic virus as a model of ribonucleoprotein localization and transport. The identification and characterization of plant components involved in viral transport, combined with the use of inhibitors of cellular processes and microscopy for the in vivo visualization of fluorescent proteins and labeled RNA are among the tools used to gain knowledge on RNA transport in plants.
