Species of virus
Carica papaya MS4113 (non-diseased)
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]
