‘GMO’ is the abbreviation for ‘genetically modified organism’. There is some controversy about the GMO papaya owing to lack of awareness and education of the general public of the pros and cons of this type of genetic engineering. There is a lot resistance towards GMO papayas which would help to reduce import and thereby the cost of this popular fruit in countries where this tree cannot grow naturally.
