Papaya Lethal Yellowing Virus (PLYV) is an isometric viral plant pathogen, tentatively assigned to the genus Sobemovirus,[1] that causes lethal yellowing disease of the papaya plant.[2]
The virus infects only Carica papaya, Jacaratia heterophylla, J. spinosa, Vasconcellea cauliflora, V. monoica and V. quercifolia, all from the papaya family Caricaceae.[3] It is only found in Northeastern Brazil and has no confirmed biological vectors.[4] PLYV consists of a 36 kDa capsid protein[3] and a single-stranded RNA genome 4145 nt in length,[1] and causes progressive leaf yellowing and greenish circular spots on the fruits.[4] Control of this virus is of economic importance in Northeast Brazil, as 60% of Brazil’s papaya production occurs there.[5]
