Research of Special Interest

Research Interest
Light is one of the key environmental signals that influences plant growth and development. In addition to being the primary energy source for plants, light also controls multiple developmental processes in the plant life cycle, including seed germination, seedling de-etiolation, shade avoidance, and flowering time.  Plants can monitor almost all facets of light by using different classes of photoreceptors, among which, phytochromes primarily responsible for absorbing the red (R) and far-red (FR) wavelengths (600-750 nm). The Arabidopsis genome encodes five phytochromes, phyA-phyE. phyA is the primary photoreceptor responsible for mediating photomorphogenic responses in FR light, whereas phyB is the predominant phytochrome regulating de-etiolation responses in R light. We are especially interested in how FR light signal is transduced in plants. The phenotypes of wild-type (WT) and phyA mutant seedlings grown in darkness or continuous FR light are shown below:

In addition, we are also interested in the cross talk between plant photomorphogenesis and stress responses, which is, however, poorly understood.  A combination of cellular, biochemical and genetic approaches will be adopted to investigate the molecular mechanisms underdying the cross talk between light signal transduction and stress responses in plants.
