Assessment of genetically modified maize DP51291 (application GMFF-2021-0071) by Corteva Agriscience

TESTBIOTECH Background 12 - 12 - 2024

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.
