|Honeysweet GM Plums|
Virus-Resistant against plum pox virus
USDA approved but not yet commercialized
The reason for the lack of GM research on fruit and nut trees is that it is more complicated in woody tree crops than other crops. After reviewing published GM research and issued field trial permits on woody tree crops from 2000 to 2011, the article concludes that:
- citrus and grape were the most studied fruits
- walnuts, and not almonds, were the focus among nut crops
- most of research initiatives already undertaken focus on finding resistance against the top-identified pests and diseases.
- trans-grafting (grafting a GM transgenic rootstock to a conventional wild-type scion) offers the most promising GM technology in addressing disease-resistance and insect-resistance.
