Technical Abstract: Orthotospoviruses belong to the family Tospoviridae (OrderClass: Bunyaviricetales) and Genus Orthotospovirus. The family includes a single genus (Orthotospovirus) with 26 species transmitted through various species of thrips in a circulative propagative manner. Orthotospoviruses have a wide host range and distributed worldwide causing significant economic losses on many agriculturally important crops. The Orthotospovirus genus is composed of 26 virus species approved by the International Committee on Taxonomy of Viruses (ICTV) and a few tentative species. They have some common features and biological properties. Tospoviruses are negative-sense RNA viruses with ambisense genomes, usually divided into three segments: a small (S) segment. M (M) segment and a large (L) segment. The S segment typically encodes the nucleoprotein (NP), the M segment encodes the glycoprotein precursor (GPC), while the L segment encodes the RNA-dependent RNA polymerase (L) and a zinc-binding protein (Z). Overall, the historical account of the increased diversity of tospoviruses underscores their adaptive capacity and ability to thrive in diverse environments. Understanding the factors driving their evolution and spread is crucial for developing effective strategies for disease management and control in agricultural systems.
