that 90% of soy products and 60% of maize
products tested in South Africa contained GMOs.
How are the new varieties
created?
Insect resistance: The bacterium Bacillus
thuringiensis (Bt) is toxic to certain insects. Scientists
incorporate the gene from this bacterium
that makes it toxic to insects, into the plant. The
production of this toxin in the plant protects it
against the insect attack. The GM plant becomes
known as, for example, Bt cotton or Bt maize.
Herbicide (weed killer) tolerance: A gene
from a bacterium is introduced into the plant to
make it less sensitive to harmful effects of herbicides.
In this way, herbicides can be used on
crops to kill weeds and invasive plants while not
affecting the crops.
Virus resistance: Genes from a virus which
causes disease are incorporated into the plant.
These genes allow the plant to become resistant
to the disease.
The specific GM technology used in South
African GM crops were all developed overseas.
Now South African scientists are researching and
developing GM crops to solve problems specific
to Africa, such as crops resistant to drought,
maize resistant to virus infection and crops with
improved nutritional content. For example, they
are transferring genes from the indigenous ‘resurrection’
plant Xerophyta viscose, which is naturally
drought tolerant, to crops which are
affected by drought. Maize resistant to a virus
called maize streak virus (a disease with a major
economic and social impact in sub-Saharan
Africa), is also being developed.
