History of the genetically modified papaya
What is PRSV?
PRSV stands for Papaya Ringspot Virus. This virus affects papayas and other cucurbits (melon, pumpkin, squash, and cucumber). When the cucurbits are infected they develop harmful symptoms such as, dark rings, bumps,streaks on the leaf and bad taste. Aphids known as plant lice helps transmit the papaya virus tree to tree feeding on tree sap (Gonsalves, DS.Tripathi,2010)
What is the main purpose for the creation of your genetically modified organism?
Advantages: To society and environment
- You don't have to worry about the ring-spot virus.
- Spend less money producing more food
- Saved the papaya industry
Advantages to environment
- Your using fewer pesticides and herbicides
- You don't have to remove weeds or anything when they grow in the soil, you are saving your soil (Leigh Erin Connealy, M.D., 2013)
Risks: To society and environment
Risks to society
- By scientists creating this gm papaya, papaya farmers lost half of their jobs, they have no job anymore because of what the scientists created.
- Safety not tested in long term for what it will do to our bodies
- It may have long term effects on consumers. (W.H.O, 2015)
Risks to environment
- Disrupts food chains
- environmental groups and health organizations believe that genetically modified papayas could be harmful to consumers in the long term (W.H.O, YEAR).

The ring-spot virus
The ringspot virus causes ring shaped spots
on infected papayas.
The ringspot virus
This is why scientists created the rainbow papaya
These are genetically modified papayas
Two varieties of papayas
On the left is the organic papaya and on the right is the genetically modified papaya.
