Title: Understanding the genetic architecture of complex traits

Host: Andrei Chabes, Medchem

Place: KB3A9, Lilla hörsalen


Abstract:

Understanding how genes contribute to the phenotypic variability observed in populations is a major challenge in biology. A common approach to dissect the genetics of complex traits is to measure the genotype of individuals in a population at a large number of loci across the genome and then evaluate whether the phenotypic mean differs between the individuals that carry particular combinations of genetic variants, alleles, at either individual loci (i.e. detection of additive, dominance and epigenetic effects of loci) or at multiple loci (i.e. to detect genetic interactions or epistasis). I will here give a brief introduction to this topic and illustrate the insights that can be gained into the genetics of complex traits using these approaches by using examples from our research in domestic animals. An alternative, and promising, strategy to identify genes involved in gene-by-gene or gene-by-environment interactions is to search for loci that causes a difference in variance (a variance heterogeneity) between genotypes. This talk will be concluded by presenting some recent work to develop theory and tools for genome-wide mapping of individual variance-controlling loci. Empirical findings from studies of data in Arabidopsis thaliana and Saccharomyces cerevisiae will be used to illustrate the contribution of such loci to the genetic architecture of complex traits and the implications of the findings on our understanding of the genetic regulation of complex trait variation.

Title:

Modifying cell wall composition to enhance the production of biofuels and nanomaterials


Place:
Lilla hörsalen, KB3A9, KBC

Host: Hannele Tuominen

The production of fermentable sugars from lignocellulosic biomass is affected by the chemical composition of the cell wall. Lignin content and subunit composition appear to be of particular importance. We have generated and studied several different classes of cell wall mutants of maize and sorghum to define how variation in lignin composition impacts biomass conversion, to identify the underlying genes, and to explain the biochemical basis of enhanced conversion using fluorescently labeled cellulases. The success of the bio-economy also depends on economic and environmental sustainability. I will highlight how the waste stream of the biorefinery can be used to produce nanomaterials as high-value co-products that have the potential to offset the cost of biofuel production.

Title: Ambient Temperature Sensing in Plants

Abstract:
How is temperature sensed? Eukaryotic cells respond within minutes to changes of a few degrees celsius, adjusting the expression of thousands of genes. The cell must therefore have a mechanism for sensing temperature and coordinating the transcriptome. Despite a few examples of thermosensors, e.g. in Listeria and neurons, the pathways by which temperature is sensed globally are not known.

To address this, we have carried out a genetic screen in Arabidopsis using a Luciferase reporter line for mutants that incorrectly sense non-stress temperature changes. This approach has enabled us to identify a novel temperature-sensing pathway that appears to be conserved among eukaryotes and accounts for the majority of the transcriptional changes in response to temperature change. We are now collaborating with other labs to more fully understand the molecular basis of temperature perception.

What is the underlying regulatory logic of the flora transition? While much is known of the genetic architecture of the floral transition, the dynamic properties of the floral switch are not clearly understood. To address this, we are collaborating with the Richard Morris group (JIC, Norwich) to model the regulatory architecture of the floral transition. This modelling has given insights into how the dynamics of flowering are regulated both spatially and temporally. Our model makes a number of testable, predictions about the dynamic regulation of the floral transition.

Title
Evolutionary origin of photorespiration: Phylogenetic and biochemical studies of enzymes involved in the 2-phosphoglycolate metabolism

Place: Lilla hörsalen, KB3A9

Abtract:The photorespiratory pathway is essential for organisms performing oxygenic photosynthesis, cyanobacteria, algae and plants, in the present day O₂-containing atmosphere. The presence of a plant-like 2-phosphoglycolate cycle in cyanobacteria indicated that not only genes of oxygenic photosynthesis but also genes encoding photorespiratory enzymes were endosymbiotically conveyed from ancient cyanobacteria to eukaryotic oxygenic phototrophs. BlastP analyses with plant photorespiratory proteins identified several proteins in cyanobacteria and algae with surprisingly high sequence similarities. To verify that not only the sequence but also the biochemical activity of these enzymes is conserved, selected proteins from the cyanobacteria Synechocystis PCC 6803, Anabaena PCC 7120 and Cyanothece sp. PCC 7822, as well as from the algae Chlamydomonas reinhardtii and Cyanidioschyzon merolae were overexpressed in E. coli and biochemical analyzed. As examples, data will be presented on our recent analyses of glycolate oxidases and hydroxypyruvate reductase, which allowed to date the origin of photorespiration back to the protoalgae
