All Phloem-Limited Aphid-Borne Plant Viruses

Plant viruses that live mainly in the phloem, the sugar-carrying tubes of the plant, and are carried from plant to plant by aphids that feed there, including the luteoviruses, closteroviruses, nanoviruses and the groundnut rosette complex. A virus belongs here when its cited article names aphids as the vector and describes infection of the phloem or places it in one of those groups. They cause yellowing, stunting, rosetting and decline, and several have shaped crop history, such as the epidemics of citrus tristeza and the spread of barley yellow dwarf through cereal fields. Management relies on virus-free planting material, resistant or tolerant varieties, control of aphid populations and removal of infected plants. This heading gathers them so a visitor can compare their hosts and vectors.
