Introduction Expand

MON 87427 expresses the CP4 epsps gene in a tissue-specific manner, in that the gene is expressed in most tissues of the plant, but not in pollen microspores nor in the tapetum. This tissue-specific expression allows glyphosate to be used to selectively kill the male flower parts of the maize plant, to facilitate the production of hybrid seed.

Summary of Introduced Genetic Elements Expand

Code Name Type Promoter, other Terminator Copies Form
CP4 epsps 5-enolpyruvyl shikimate-3-phosphate synthase HT

P-e35S promoter from Cauliflower Mosaic Virus; I-hsp70 intron from maize heat shock protein; TS-CTP2 chloroplast transit protein from Arabidopsis thaliana.

T-nos nopaline synthase terminator from Agrobacterium tumefaciens.


Characteristics of Zea mays (Maize) Expand

Center of Origin Reproduction Toxins Allergenicity

Mesoamerican region, now Mexico and Central America

Cross-pollination via wind-borne pollen is limited, pollen viability is about 30 minutes. Hybridization reported with teosinte species and rarely with members of the genus Tripsacum.

No endogenous toxins or significant levels of antinutritional factors.

Although some reported cases of maize allergy, protein(s) responsible have not been identified.

Donor Organism Characteristics Expand

Latin Name Gene Pathogenicity
Agrobacterium tumefaciens strain CP4 CP4 epsps

Agrobacterium tumefaciens is a common soil bacterium that is responsible for causing crown gall disease in susceptible plants. There have been no reports of adverse effects on humans or animals.
