Modified growth characteristics resulting from the additional expression of the AN3 gene under the control of the EF1a promoter. This gene is a transcriptional co-activator that is involved in the regulation of cell proliferation. As a result of the modification the duration of growth is elongated which results in the formation of larger plant organs such as larger leaves. It is also results in the formation of more biomass.

Project title: 
Scientific field evaluation of maize with modified growth characteristics
Year(s) of release: 
2020, 2021, 2022
Period of release: 
15/04/2020 to 31/10/2022
Municipality of Wetteren
Number of sites: 
Total surface: 
1100 m2
Containment measures: 

The risk of spread of the modified properties to the environment is mitigated by removing the tassel, thus preventing the spread of modified pollen to non-modified maize plants in the surroundings. The formed modified seeds are, as already stated above, well retained in the cobs and these cobs will be very carefully hand harvested, thus preventing any spread of seeds to the environment. Experience with such field trials in the past 8 years has shown that the way the cobs are harvested effectively prevents any volunteers being formed. The field trial plot is surrounded by a 1.80 m high wire fence to prevent accidental trespassing and accidental removal or spread of GM material.
