Masterarbeit aus dem Jahr 2013 im Fachbereich Biologie - Genetik / Gentechnologie, Note: 1,0, Gottfried Wilhelm Leibniz Universität Hannover (Pflanzen Genetik), Sprache: Deutsch, Abstract: Genetically modified plants, which are used in the production of industrial materials or
pharmaceuticals instead of feed and food production, are nowadays referred to as
pharmaceutical plants. Due to genetic modification, these pharmaceutical plants
produce important proteins (vaccines or antibodies) for pharmaceutical use as
enzymes for different applications. In order to produce these proteins/enzymes the
coding DNA are incorporated into the genome of plant where the plants will express
the protein to high level producing low cost molecules compared with other
expression systems like cell culture, hypridoma, fermentas. As well as, when the
target proteins has a lethal effect on E.coli hindering the overexpression. In temperate
climates such as Northern Germany the lungworm (Dictyocaulus viviparous) is one of
the economically most important parasites of cattle. This parasite causes parasitic
bronchitis disease, which occurs in varying intensity and-in some cases-can lead to
death of the infected animals.
It was possible to control a lung worm infection with anthelmintics and even in some
countries with a live vaccine, which consists of X-ray attenuated larvae and pasturage
technical measures. This vaccine can only induce a robust immunity in cattle for a
few months. In addition, the production of these vaccines is very costly and suffers
from limited durability. Therefore, an attempt was made in this work to produce
recombinant proteins in high purity and in large amounts by using tobacco plants and
to use these proteins instead of the previously available immunization as a vaccine
with high efficiency.
First, the vectors were constructed harbouring SOD (superoxide dismutase
pGIIMH35S-SOD vector size approximately 6138 bp). and
