Abstract
Virology as a science began when Dimitri Ivanovsky in 1882 showed that "the
sap of leaves infected with tobacco mosaic disease retains its infectious
properties even after filtration through Chamberland filter candles". Since
that time, and well-beyond the essential goal of crop protection, virology
studies conducted in plants have made seminal contributions to science with
such landmark demonstrations as the infectious nature of nucleic acids, RNA
silencing, and identification of host factors with roles in viral replication and
recombination. This presentation considers how plant virology can inform
the most pressing epidemiological concern of our time under the hypothesis
that; if plant virology can inform zoonotic virus emergence, then the two
should share in common: “outbreak” phenomena (sudden
appearance), “spillover” phenomena (transfer from wild to domesticated
areas), common genetics (similar types of viruses), reliance on ”vectors” for
viral spread, and maintenance of viruses in “reservoir” species.
