Virus Transmission—Getting Out and In

  • Stéphane BlancEmail author
Part of the Plant Cell Monographs book series (CELLMONO, volume 7)


Logically, most plant viruses being vector-transmitted, the majority of viral transport mechanisms associated to the transmission step have been approached through the study of virus-vector relationships. However, in the case of non-vector vertical transmission through the seeds, some viruses have evolved specific patterns to colonize either the gametes or the embryo, thereby connecting viral transport within the plant to that in between plants. Moreover, though it may appear counter intuitive and has been largely overlooked, some specific virus accumulation within cells or organs, as well as specific control of multiple infections of single cells, can also directly affect the success and efficiency of vector transmission, again connecting viral transport mechanisms inside and outside the host plants. This work summarizes the data available on viral transport outside the plant in various vectors, and also highlights a few available examples and proposes hypotheses for illustrating the concept that some viral trafficking within plants is specifically intended to prepare ulterior acquisition by the vectors.
