Papaya ringspot virus (PRSV) is a pathogenic plant virus [1] in the genus Potyvirus and the virus family Potyviridae which primarily infects the papaya tree. The virus is a non-enveloped, flexuous rod-shaped particle that is between 760–800 nm long and 12 nm in diameter.
Papaya leaf curl virus (PaLCuV) is a DNA virus from the genus Begomovirus and the family Geminiviridae. PaLCuV causes severe disease in papaya ( Carica papaya ), but can sometimes infect other crops such as tobacco or tomato . [ 1 ]
Papaya mosaic virus (PapMV) is a plant pathogenic virus in the genus Potexvirus and the family Alphaflexiviridae. PapMV is a filamentous, flexuous rod, 530 nm in length. [1] The virus is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein.
The pathogen can survive in the seed of infected papaya, even after drying, for approximately 30 days (Obrero 1980). Thus far, seed-borne transmission is the predominant method of spread and infection; in fact, studies indicate the pathogen has the ability for long-range dispersal via seed (Ramachandran et al. 2015).
Rickettsia causes diseases in animals, such as typhus and spotted fever, [2] as well as in other plants, such as phony disease of peach and almond leaf scorch. [3] Papaya Bunchy Top is found throughout the American tropics and has been economically important due to its major impact on fruit production. [4]
It is responsible for the black spot disease on papaya trees. It affects generally leaves and fruits at any time. It affects generally leaves and fruits at any time. Sporodochia of Asperisporium caricae was growing under side of leaf, dark blackish brown to black, stroma well-developed, erumpent .
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 ...
