Light signaling, nuclear organization, and the control of photosynthesis

We study how plants sense and respond to changes in their light environments. Our current research focuses on understanding how photoreceptor signaling controls seedling morphogenesis by reorganization of the nuclear architecture. We also investigate how photoreceptor signaling in the nucleus communicates with the plastids to initiate chloroplast biogenesis and photosynthesis.

The outcome of our research is expected to contribute to the understanding of evolutionarily conserved principles of subnuclear organization and transcriptional regulation in eukaryotes. A better understanding of light signaling and the control of chloroplast biogenesis will have profound implications for developing new tools and technologies to improve the photosynthetic capacity and yield of crops and energy plants in agriculture.
