Abstract

The corn rootworm (CRW; Diabrotica spp.) is one of the most serious pests of corn in the USA. Chemical insecticides and crop rotation have been the only two options available to growers for managing CRW. Unfortunately, both of these tactics can be ineffective as a result of either resistance or behavioral modifications. In this paper, we describe transgenic maize (Zea mays L.) hybrids that control CRW. These hybrids were created with a Cry3Bb1 Bacillus thuringiensis (Bt) variant that is approximately eight times more lethal to corn rootworm larvae than the wild‐type protein. A DNA vector containing the modified cry3Bb1 gene was placed under control of a root‐enhanced promoter (4‐AS1) and was introduced into embryonic maize cells by microprojectile bombardment. Described here is the molecular genetic characterization, protein expression levels, and field performance of the recently commercialized MON863 hybrids.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
