The world population is expected to reach an estimated 9.2 billion by year 2050. Therefore, food production globally should increase by 70 percent in order to feed the world, while total arable land, which has reached its maximal utilization, may even decrease. Climate change adds yet another challenge to the food security problem. In order to feed the world in 2050, biotechnological advances in modern agriculture are essential. After the first green revolution, plant genetic engineering has offered a new tool to incease global crop production and this will continue to play an important role in modern agriculture to meet global challenges. To enhance crop biomass through improved agronomic traits and increase photosynthetic capacity via the chloroplast genome will be of importance in the years ahead. Chloroplast genome engineering, with several unique advantages, especially transgene containment, has made significant progress in the last two decades in various biotechnology applications including development of crops with high levels of resistance to insects, bacterial, fungal and viral diseases, different types of herbicides, drought, salt and cold tolerance, cytoplasmic male sterility, metabolic engineering, phytoremediation of toxic metals and production of many vaccine antigens, biopharmaceuticals and biofuels. Chloroplast genomes of several major crops have been transformed. These advances should promote crop productivity under a changing climate. This talk will give a brief insight into the current state of the art of plastid engineering in relation to agricultural production, especially for engineering of agronomic traits and improvement of crop biomass. The future direction of this technology and challenges for improvement of cereal crops to enhance their biomass for food security in a changing climate with special emphasis on elevated CO2 will be presented.

Fish nodaviruses (betanodaviruses) are small, non-enveloped icosahedral single-stranded positive-sense RNA viruses that can cause viral encephalopathy and retinopathy (VER) in a number of cultured marine teleost species. The main target organ for NNV infection of fish is the central nervous system (CNS) leading to cellular vacuolation and neuronal degeneration predominantly in larval and juvenile fish, resulting in high mortalities. NNV has been reported to affect around 40 different fish species from all over the world and has been a major limiting factor in the culture of sea bass (L. calcarifer) in India and Atlantic halibut (Hippoglossus hippoglossus) in Norway. The recent finding of VNN affecting farmed Atlantic cod (Gadus morhua) in Norway has caused concern in the aquaculture industry. These observations indicate that the strains are geographically rather than species-related and it is therefore important that vaccines against NNV protect the fish against area-specific strains. Here we report the expression of recombinant nodavirus antigens in tobacco chloroplasts. The vaccine candidates will be evaluated once they have been produced.

Julestjerne er en av de viktigste potteplantene i verden. Julestjerne er den potteplanten det lages flest av i Norge, rundt 6 millioner planter hvert år. Førstehåndsverdien for julestjerne produsert i Norge er rundt 75 mill kroner og utsalgsprisen 4-5 ganger høyere.
