Our research group moved
from
the University
of Goettingen
(Germany) to the newly founded Centre
for Organelle Research (CORE)
of the University
of Stavanger
(Norway) in 2008. A second laboratory is presently set up at the Biocentre of the University
of Hamburg (Germany). The
research interest and activities of our group focuses on basic and
biotechnological research of
plants and microalgae. We carry out molecular cell biology
research and are trying to understand and optimize the
function of
plant peroxisomes in
diverse biological processes. Peroxisomes
are cell organelles that are
present in most higher organisms and play
essential roles in nearly all organisms
on
earth, including
animals,
fungi and plants. These
"microbodies" are well-known for their important physiological
functions in
photorespiration, fatty acid beta-oxidation and ROS metabolism.
However, due to technological challenges, many proteins,
enzymes, metabolic pathways and important functions of plant
peroxisomes have remained
unknown to date. To define the proteome of plant peroxisomes our group developed experimental proteome technology for the model plant Arabidopsis thaliana (more on Proteomics). Complementary to this experimentally challenging approach, we developed, in collaboration with Dr. Thomas Lingner (University of Goettingen, Germany) computational prediction algorithms to predict the major class of peroxisomal matrix proteins carrying peroxisome targeting signals type 1 (PTS1) from genome sequences (more on Bioinformatics). At the molecular level
our
research
focuses on the function of plant
peroxisomes in plant
innate immunity (more
on Innate immunity).
Recent activities also center on metabolic pathways that
facilitate plant
adaptation to
environmental stress conditions
such as
heat (more on
Stress adaptation).
Recently, we also became interested in the evolution of peroxisomes
and
started analyzing and comparing the proteome of peroxisomes from higher
plants and microalgae.
In biotechnology
research we are
trying to understand
and
optimize
fatty
acid metabolism in microalgae
to increase their enormous
oil
productivity. Omega-3 rich oil from marine microalgae is of
particularly high interest to
Norwegian aquaculture such as salmon farming (more on Microalgal research).
