Luteoviridae

The plant viruses belonging to this family often cause yellowing symptoms in their hosts. They are transmitted by aphids in a persistent, circulative, non-propagative manner, but not mechanically. Once the aphids have acquired the virus, they stay infectious for days or weeks and even after molting. The particles are non-enveloped, isometric (spherical) with a diameter of 25-30 nm. The genome is monopartite, linear and composed of ssRNA(+) with a length of 5.3-5.7 kb.
