Zambrana - Echevarria is about to defend her masters degree at the University of Puerto Rico, Mayagüez, on genetic diversity in papaya
ringspot virus on the island, and deciding between Ph.D. programs at U.S. universities.
The bottle gourd genome provides insights into Cucurbitaceae evolution and facilitates mapping of a
Papaya ringspot virus resistance locus
The
tobacco ringspot virus was likewise linked recently to the highly publicized problem known as «colony collapse disorder.»
There are 30 known orchid viruses, but when growers say a plant has «a virus» they usually mean one of the two most prevalent: Cymbidium mosaic virus (CMV) or
Odontoglossum ringspot virus (ORSV).
The virus,
called ringspot, has decimated nearly all of Thailand's papaya, a staple food that many Thai people eat three times a day.
Almost all of the papaya trees in Hawaii are genetically engineered to resist the
devastating ringspot virus, and similar efforts are under way to save the American chestnut, which has been nearly eradicated by fungal disease.
FOE claims that these pesticides are responsible for massive bee kills — but peer reviewed science shows that the bees were being attacked by the
tobacco ringspot virus.
Also, common diseases include canker, armillaria root rot, and
ringspot viruses.
Some are eaten as a whole organism — such as papaya engineered to resist
the ringspot virus.
While not processed in the traditional sense, Hawaiian GE papaya is genetically engineered to be resistant to
the ringspot virus.
