1. Cold Acclimation : Dissecting the plant low temperature signaling pathway using functional genomics
Sammanfattning : The physiological process of cold acclimation protects plants native to the temperate regions of the world from the deleterious effects of low and freezing temperatures. This is achieved by a series of transcriptional, regulatory, and metabolic changes that enable continued growth and survival. Within minutes of exposure to temperatures below ca. LÄS MER
2. In the quest for a cold tolerant variety : gene expression profile analysis of cold stressed oat and rice
Sammanfattning : Cold acclimation is a process which increases the freezing tolerance of an organism, after exposure to low, non-freezing temperatures. The acclimation ensures that cold tolerant species can endure harsh winter conditions, by preparing them to sub-zero temperatures. LÄS MER
3. Natural variation in cold adaptation and freezing tolerance in Arabidopsis thaliana
Sammanfattning : Plants have spread to almost everywhere in the world. As they disperse, they meet many different environments to which they may be able to adapt. For a plant species to adapt to a new environment, genetic variation is needed. The individuals differ from each other in their genetic composition, which often means differences in phenotypes.

4. Thriving in extremes : Local adaptation of grasses (Poaceae) to geothermally heated soils on a subarctic island
Sammanfattning : Temperature is one of the most decisive parameters when it comes to determining characteristics and distributions of life worldwide. For plants, as sessile organisms, it is particularly important to be able to deal with the temperatures they are exposed to at a given location. LÄS MER
5. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification
Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.
