The GMO Panel assessed maize DP51291 (EFSA, 2024a). The maize produces
- IPD072Aa toxin from the soil bacterium Pseudomonas chlororaphis (to act against corn rootworm),
- the phosphinothricin acetyl transferase (PAT) protein for tolerance to glufosinate-ammonium-containing herbicides,
- the PMI protein (as a selectable marker).
Consequently, the maize is resistant to glufosinate herbicides and toxic to corn rootworm. The genetic intervention involved a multistep process to introduce a ‘landing pad’ at the target site, where the gene constructs for the production of new proteins (new traits) are subsequently inserted.
