Six Years of Field Data in Hawaii Show Pollen Drift from GE Papaya is Very Low

Between 2004 and 2010, pollen drift from GE papaya to non-GE papaya was examined in commercial plantings and replicated field trials by Dennis Gonsalves and co-investigators. Results showed very low levels of transgene flow to non-GE papaya, most likely due to the self-pollinating characteristic of commercial varieties. The results also suggest that organic farmers could […]

Frequency of Pollen Drift in Genetically Engineered Corn

Frequency of Pollen Drift in Genetically Engineered Corn

The frequency of pollen flow with distance in corn is demonstrated and explained well in this report on GE and non-GE hybrids grown in close proximity at three locations over three years. The simple dominance of the yellow colored GE kernels shows the relationship visually: B. L. Ma, February, 2005 Cross fertilization and concerns over […]

Is there potential for movement  of genes between GM plants and others?

Is there potential for movement of genes between GM plants and others?

By Ania Wieczorek, Biotech in Focus, University of Hawaii, August 2014 It is possible that genes may move among GE crops and other closely related plants. A closely related plant is generally of the same species as the crop plant. Science has found that under certain conditions rare gene flow to another species does occur: […]
