Tospovirus
A Viral Biorealm page on the family Tospovirus
Baltimore Classification
Group V (negative sense ssRNA)
Higher order categories
Bunyaviridae
Species
Tomato spotted wilt virus (TSWV); Impatiens necrotic spot virus (INSV); Watermelon silver mottle virus (WSMoV)
Description and Significance
Tospoviruses infect plants.
Genome Structure
The tospovirus genome consists of three ssRNA molecules. The molecules are simply known as L (Large), M (Medium), and S (Small). The entire genome codes for six proteins via five different open reading frames (ORFs). The L RNA encodes the virus' RNA-dependenT RNA polymerase (L protein). The M RNA encodes two envelope precursor glycoproteins (G1 & G2) and a viral movement protein (NSm). The S RNA encodes the nucleoprotein (N) and a non-structural protein (NSs).
