What is "luteovirus"

Luteovirus is a genus of viruses, in the family Luteoviridae. There are currently eight species in this genus including the type species Barley yellow dwarf virus-PAV. Plants serve as natural hosts. The geographical distribution of Luteoviruses is widespread, with the virus primarily infecting plants via transmission by aphid vectors. The virus only replicates within the host cell and not within the vector 1. The name 'luteovirus' arises from the Latin luteus, which is translated as 'yellow'. Luteovirus was given this name due to the symptomatic yellowing of the plant that occurs as a result of infection.
