16. Non-genetic processes in development and heredity
Sammanfattning : There is a swiftly increasing amount of empirical evidence that non-genetic factors, such as DNA methylation and small RNAs, play an important role not only in development but also in heredity and, therefore, evolutionary dynamics. One of the most interesting aspects of non-genetic processes is their responsiveness to environmental conditions, which has been shown to affect not only the phenotype and fitness of the individuals directly exposed to the stimulus, but also their offspring even when the stimulus is no longer present, indicating that the transmission of non-genetic factors across generations might work analogously to immunization against recurring conditions.

17. Functions of Heparan Sulfate During Mouse Development : Studies of Mice with Genetically Altered Heparan Sulfate Biosynthesis
Sammanfattning : Heparan sulfate (HS) is a ubiquitous polysaccharide on the cell surface and in the extracellular matrix. HS is an important actor in the regulation of cell signaling, especially in the developing embryo. LÄS MER
18. Regulation of site-selective A-to-I RNA editing : During mammalian brain development
Sammanfattning : Adenosine (A) to inosine (I) RNA editing is a widespread post-transcriptional mechanism in mammals that contributes to increase the protein diversity. Adenosine deaminases that act on RNA (ADARs) are the enzymes catalyzing RNA editing. ADARs are particularly active within the brain where they act on transcripts involved in neurotransmission.

19. Cell-to-Cell Signalling in Arabidopsis Root Development
Sammanfattning : Development in multicellular organisms requires a strict balance between cell division and differentiation. The simple architecture of the Arabidopsis thaliana root makes it an ideal model for studying molecular mechanisms controlling both the transition from cell division to cell differentiation and cell fate determination.

20. Effects of domestication related genes on behaviour, physiology and gene expression in chickens
Sammanfattning : Domestication, the process when animals adapt to captivity, tends to modify a whole array of traits towards what has been termed “the domesticated phenotype”, where the domesticated animal differs from its wild ancestor in morphology, physiology, development and behaviour. Physiological traits and behaviours are controlled by genes. LÄS MER
