Plant negative-stranded RNA virus biology and host interactions revitalized by reverse genetics

Our understanding of the biology and pathogenesis of plant negative-stranded RNA viruses (NSVs) has lagged behind those made with positive-stranded RNA and DNA virus counterparts. This tardiness is mainly due to the lack of reverse genetics tools for NSV genome engineering for many years. The eventu...

Description
Summary:Our understanding of the biology and pathogenesis of plant negative-stranded RNA viruses (NSVs) has lagged behind those made with positive-stranded RNA and DNA virus counterparts. This tardiness is mainly due to the lack of reverse genetics tools for NSV genome engineering for many years. The eventual establishment and application of recombinant systems with diverse plant NSVs has provided renewed momentum for investigations of these important viral pathogens. In this review, we summarize the recent advances in plant NSV reverse genetics systems, highlighting the general principles and the uniqueness of each system and emphasizing important considerations for strategy designing. We also provide a brief overview of the insights about NSV morphogenesis, movement, and virus-host interactions gained from reverse genetics-enabled studies.
