Nicotiana benthamiana : Its History and Future as a Model for Plant–Pathogen Interactions

Nicotiana benthamiana is the most widely used experimental host in plant virology, due mainly to the large number of diverse plant viruses that can successfully infect it. Additionally, N. benthamiana is susceptible to a wide variety of other plant-pathogenic agents (such as bacteria, oomycetes, fungi, and so on), making this species a cornerstone of host-pathogen research, particularly in the context of innate immunity and defense signaling. Moreover, because it can be genetically transformed and regenerated with good efficiency and is amenable to facile methods for virus-induced gene silencing or transient protein expression, N. benthamiana is rapidly gaining popularity in plant biology, particularly in…
