A wide variety of biological processes exhibit a rhythmic pattern of activity with a period of 24 hours. The temporal coordination of these rhythms is regulated by a cellular endogenous mechanism known as circadian clock. From bacteria to humans, the presence of the circadian clock has provided a remarkable adaptive advantage throughout evolution. In plants, the temporal synchronization of physiology with the environment is essential for successful plant growth and development. The intimate connection between light signaling pathways and the circadian oscillator allows the anticipation of the environmental transitions and the measurement of day-length as an indicator of changing seasons.
Current research in our group focuses on identifying new components and mechanisms of circadian clock progression in Arabidopsis thaliana. We are interested in elucidating the regulatory networks and the functional modules underlying the circadian clock function. Our research also focuses on studies about chromatin remodeling and the molecular determinants responsible for modulating the circadian activity. We also study the role of post-transcriptional regulation at the core of the clock and the impact of circadian clock function on plant growth and development. We apply to our studies a combination of genetic, biochemical, cellular and molecular approaches to obtain a comprehensive view of the interactive networks underlying circadian clock progression in plants.
