Area of Focus
- Plant root response to biotic and abiotic stresses
- Plant single cell biology
- Comparative genomics
My long term objective is to understand the molecular mechanisms controlling the transcriptional response of agricultural crops to various environmental stresses. Specifically, my lab is working on revealing with great accuracy the influence of the epigenome and binding of transcription factors on crop gene expression in response to biotic and abiotic stresses. To generate unambiguous transcriptomic, epigenomic and functional genomic data sets, my research focuses on plant single cell and single cell-type models such as the root hair cell (RH), a single plant cell type specialized in water and nutrient uptakes. The focus on one single plant cell type represents a unique and integrative systems biology approach to understand then enhance plant response to various environmental stresses including plant response to abiotic stresses and plant-microbe interactions (i.e., legume RH infection by rhizobia). In addition, to develop a more fundamental knowledge of the RH, my lab is also characterizing the evolution of the molecular mechanisms controlling the unique biological properties of the plant RHs (e.g., polar elongation, water and nutrient uptakes). Ultimately, a better understanding of the molecular mechanisms controlling RH development and the adaptation of the RH to environmental stresses will help to enhance RH biology to mitigate climate change, to enhance plant response to environmental stresses and to maximize crop yields.
