Research Categories: Light signaling and nuclear organization in plants

Research Description: Research in my laboratory is aimed at understanding how light controls plant development through the red and far-red photoreceptors, photochromes. In particular, we focus on answering the following three interrelated questions: (1) How does phytochrome signaling regulate transcription by controlling nuclear organization? We are particularly interested in a light-dependent phytohchrome-containing subnuclear domain named photobody and the phytochrome-regulated spatial organization of individual light responsive genes. (2) How does phytochrome signaling control the stability and activity of master transcription factors? (3) How does phytochrome signaling in the nucleus control transcription in the plastids to coordinate nuclear/plastidial gene expression? We use Arabidopsis thaliana, an ideal genetic model species, and a combination of genetic, cell biological, biochemical, and genomic approaches to address these questions.
