Populus genomics
The ultimate goal of this project is to learn how to find the genetic differences that make aspens (Populus tremula) different from each other. Forest trees are, in general, more genetically diverse than most other organisms and aspens are, in this respect, extreme. Gene sequences from two aspens are on average 1 % different; two aspens are about as different genetically as humans are from chimpanzees.
We have been developing infrastructure to enable research on genomics and natural variation in aspen. For example, we have generated Populus ESTs and DNA microarrays, developed microarray analysis protocols and databases, genome databases and have been profiling small RNAs. To study natural variation, we have used both genetic genomics to study gene expression in segregating populations, and have created clone collections (the SwAsp and UmAsp collections) that are phenotyped for many traits and genotyped for variation in candidate genes.
Autumn senescence
Using these tools, we study how aspens acclimate and adapt to the environment. Particular attention is paid to the process of autumn senescence, trying to answer the question: How do trees know that it is autumn? We are studying gene expression, photosynthesis, metabolism and ultrastructure of the leaves during autumn senescence. One important tool we use is natural variation. There is a steep cline in autumn senescence; trees from northern latitudes enter senescence much earlier than those from southern latitudes, and by us- ing the complete annotated Populus genome sequence, the collection of aspen clones and genetic tools like association mapping, we hope to understand the genetic basis of this adaptively significant trait. The same strategies are also used to dissect other traits, including herbivory and other biotic interactions.

Photosynthetic light harvesting
stefan_3
Field experiment with transgenic Arabidopsis
In the photosynthesis apparatus of green plants, the lightharvesting chlorophyll a/b-binding (LHC) proteins serve as antennae for photosystems I and II. Members of the LHC protein family have three membrane-spanning regions and bind the majority of the photosynthetic pigments (chlorophyll and carotenoids), make the photosynthetic light reaction efficient and regulate the photosynthetic light reaction, for example by dissipating excess light and adjusting the excitation balance between the photosystems. There are a group of proteins that are more distant members of this protein family. This group consists of PsbS, ELIPs (early light-inducible proteins) and several smaller proteins, containing only one or two membrane-spanning regions. PsbS is necessary for a light dissipation process – the qE type of non-photochemical quenching (NPQ) or feedback de-excitation (FDE) - that operates when the plants is exposed to "excess light".
We are studying the large family of LHC proteins using biochemical, reverse and forward genetic and molecular biological approaches. In Arabidopsis, over 30 genes encode proteins of this family and we are systematically producing and analysing plants that lack different LHC proteins (T-DNA knockouts or antisense plants). The photosynthetic performance of these plants helps us understand the function of the individual proteins, the structure of the photosystems and energy transfer in the antenna.
