Group Interests

The induction of flowering is a central event in the life cycle of plants. When timed correctly, it helps to ensure reproductive success, and therefore has adaptive value. Because of its importance, flowering is under the control of a complex genetic circuitry that integrates environmental and endogenous signals. Genetic analyses initially suggested the existence of distinct, genetically defined pathways that regulate flowering in response to a specific input. Over the last years, however, it has become apparent that many important flowering time genes are not regulated by single inputs, but rather integrate multiple, often contradictory signals to control the induction of flowering. This provides plants with a certain developmental plasticity in their timing of the floral transition. Work in our group has so far mostly aimed to understand the precise mechanisms that govern flowering time. To this end we employ a combination of molecular biology, genetic, and high-throughput sequencing (ChIP-seq, RNA-seq) techniques to unravel the transcription factor network that integrates diverse environmental signals in the model plant Arabidopsis thaliana. More recently we have adopted the INTACT, which allows the isolation of nuclei from defined tissues and cell types, to increase the temporal and spatial resolution of our analyses. A second focus of the group is directed at understanding how trehalose-6-phosphate (and sugar signals in general) are integrated into the canonical network that regulates flowering.

The group has recently moved to the Umeå Plant Science Centre in Sweden. More information is available here.
