Abstract

It is worrisome not knowing with certainty whether native maize
may be damaged when contaminated with transgenes. The maizeteosinte
introgression does not occur or it is slight. Then, gene flow
from transgenic maize into the native one would be more extensive
and important than that occurring into teosinte. The constant
increment of DNA with genes in the form of duplications,
trisomies, etc., frequently form chromosome aberrations that cause
semisterility, besides other phenotypic anomalies inducing
malformations and defective reproduction in individuals. In
transgenic maize, transgenes are often found as duplications in
tandem in the chromosomes. Therefore, there is the possibility that
the same effects are caused by transgenes where these are
transferred to native maize in México. In this work these
possibilities are discussed, and is concluded that transgenic maize
should not be cultivated in México as long as no experimental
information is available contradicting the hypothesis here
proposed.
