As sessile organism, plant has evolved the ability to cope with various biotic and abiotic stresses. Light serves not only as energy resource for plant, but also as an important environmental signal. It directs plant development throughout its whole life span. When sun plants are under canopy shade, they often display a set of responses that are collectively referred as the Shade Avoidance Syndrome (SAS). The main output of the SAS is re-allocation of energy resources towards elongation growth at stems and petioles, which allows the plant to compete for more light. Even though the SAS is beneficial to the fitness of individual plant, it causes reduction in crop yield due to reduced deposition to leaves and storage organs in shade-avoiding crops. In addition, plants displaying the SAS also exhibit higher disease susceptibility. We are interested in the molecular mechanisms of the light and the shade avoidance signal transduction pathway and their connections to plant disease resistance. Using model plant, Arabidopsis thaliana, we are working on identifying new components of light and shade avoidance signaling pathways through a combination of genetics, biochemical and molecular biology approaches. Our long term goal is to design crops that can be planted at high density and to increase crop yield and the efficiency of land usage.
