How does one genome give rise to the different cell types that together form an organism, and how can one genome shape individuals that differ in phenotype and behaviour? It is well established that key processes in cell differentiation and development involve epigenetic modifications, i.e. marks that can influence gene expression patterns that can be transmitted across cell divisions without changes in the underlying DNA sequence. Recently, epigenetic phenomena involved in shaping responses to environmental signals have received increasing attention.  Nevertheless, we are just beginning to understand the molecular mechanisms underlying memory of past experiences in plants. Research in our lab investigates fascinating aspects of molecular memory including its generation, extend, and persistence in plants. In particular, we are interested in epigenetic phenomena such as histone modification or DNA methylation involved in this process and their relation to gene function and phenotype. Our lab combines molecular, physiological, and genome-wide approaches to study lasting effects of environmental exposure and stress responses, phenotypic plasticity and adaptive capacity in plants, aspects  potentially of special importance for plant growth and survival under scenarios of rapid climate change.
