Title: Circadian regulation of chloroplasts
Host: Maria Eriksson
Place: Lilla hörsalen KBC, KB3A9
Abstract:
Circadian timekeeping improves plant performance. Understanding the cellular basis for the circadian optimization of plant function is important, because this could unlock additional agricultural productivity. There are circadian rhythms of photosynthesis and correct circadian regulation increases plant productivity, but it is not known how the circadian oscillator regulates the photosynthetic apparatus or the chloroplast genome. I will show that in Arabidopsis, a subset of chloroplast-encoded photosynthesis genes is controlled by a nuclear-encoded signalling protein. Our findings reveal one pathway by which the nuclear-encoded circadian oscillator controls rhythms of chloroplast gene expression. I will show that light and circadian signals are integrated to adjust chloroplast transcription. I will conclude that (i) during evolution, prokaryotic transcriptional regulators in chloroplasts were recruited by the eukaryotic circadian system in higher plants, and (ii) circadian timing information is communicated between organelles with distinct genetic systems.

Computational challenges in single-cell transcriptomics – from immune cells to neurons
Room:
Lilla Hörsalen KB3A9
Abstract:
Recent technical developments, facilitated in large part by work at the Karolinska Institutet, have enabled the transcriptomes of hundreds of cells to be assayed in an unbiased manner. These approaches have enabled heterogeneity in gene expression levels across populations of cells to be characterized as well as facilitating the identification of new, and potentially physiologically relevant, sub-populations of cells.
However, to fully exploit such data and to answer these questions, it is necessary to develop robust computational methods that take account of both technical noise and underlying, potentially confounding, variables such as the cell cycle.
In this presentation I will begin by briefly describing how we used spike-ins to quantify technical noise in single-cell RNA-seq data, thus facilitating identification of genes with more variation in expression levels across cells than expected by chance. Subsequently, I will discuss a computational approach that uses latent variable models to account for potentially confounding factors such as the cell cycle before applying it to study the differentiation of Th2 cells. I will show that accounting for cell-to-cell correlations due to the cell cycle allows identification of otherwise obscured sub-populations of cells that correspond to different stages along the path to fully differentiated Th2 cells.
To conclude, I will discuss further applications of single-cell RNA-seq in the context of studying neuronal cell types, including olfactory neurons. I will also describe how we are studying heterogeneity in gene expression levels whilst taking into account the spatial location of cells from the tissue under study.

Waterproofing plants: Sensing, signaling and response mechanisms

Abstract
The development of crops that can survive extreme weather conditions is imperative due to climate change and population growth. Improving plant yields when there is too little or two much water is especially important. Flooding stress, including soil waterlogging and partial to complete submergence, reduces oxygen availability for ATP production, triggering alterations in gene transcription, mRNA translation and energy metabolism. The plant-specific Group VII Ethylene Response Factor (ERF-VII) transcription factors have emerged as pivotal regulators of flooding and low oxygen responses in plants. In rice (Oryza sativa), ERF-VIIs SUB1A and SNORKEL1/2 enable survival or escape of submergence, respectively. In Arabidopsis thaliana, there are five ERF-VIIs, which are unstable under oxygen-replete conditions due to turnover via the N-end rule of targeted proteolysis. As oxygen levels fall, the ERF-VIIs are stabilized and direct the upregulation of genes associated with anaerobic metabolism. Along with transcriptional regulation in oxygen-deprived cells, there is significant post-transcriptional control. As an energy conserving mechanism, mRNA translation is largely repressed by the sequestration of approximately 90% of the cellular transcripts in large cytosolic granular complexes. We recently reported dynamics in the movement of ribosomes along mRNAs and RNA binding protein that binds many cellular mRNAs that are sequestered during hypoxia. This protein-mRNA association is rapidly reversed upon reoxygenation, allowing stored mRNAs to resume translation. Our efforts to understand low oxygen sensing, signaling and response mechanisms are motivated by the ecological and agronomic relevance of flooding biology in light of the challenges of the 21st century.

Host: Maria Eriksson
Room: Lilla hörsalen, KB3A9
Abstract: Disturbances associated with global change are degrading natural ecosystems. But policy-makers and managers need predictions of how ecosystem functioning and patterns of biodiversity might respond to disturbances in order to intervene. My research group is addressing these needs by tackling problems around water security. We are focusing on how alterations to vegetation associated with land-use change and water extraction are, respectively, reducing the productivity of food webs in boreal lakes and persistence of biodiversity hotspots in dryland landscapes. We are finding that the local outcomes of global change may ultimately be driven by the evolutionary history of traits determining species' responses to disturbance and their competitive abilities.
Older lineages that have had longer to diversify within niche space may lose their ecological advantages as disturbance intensifies. We are now interested in testing these ideas over much larger macro-ecological scales and linking evolution in the expression of response traits to underlying genetic processes.
