Mechanisms of translational control evolved by plants viruses
Viruses have evolved various specialized mechanisms to express genes from compact viral genomes. We are interested in the mechanisms of translation initiation such as ribosome shunting and leaky scanning, in which the scanning ribosomes bypass large regions of viral mRNAs and initiate translation of several consecutive ORFs from a single polycistronic viral mRNA.
