Our lab uses molecular, genetic and biochemical approaches to uncover and describe the interactions between various signaling pathways that modulate plant development. Specifically, we use seedling development in the plant Arabidopsis as a tool for addressing the question: How do signaling pathways modulated by light interact with each other and with those regulated by endogenous hormones to control plant development? Arabidopsis is perfect for this approach due to its small size, rapid lifecycle and completely sequenced genome. Our lab’s research relates to the goal of increasing yield in agricultural crops by studying the photomorphogenic and hormone signaling pathways that regulate plant stature. Read more.
