Research Interests

Sphingolipids have been demonstrated to play important roles as both membrane components and as signaling molecules in animals and fungi and, most recently, in plants. Complex polar sphingolipids are quantitatively important components of specific plant membranes (especially the plasma membrane) and recent studies implicate particular sphingolipids in plant cell signaling. Previous work in the Lynch lab focused on the network of genes predicted to be involved in sphingolipid metabolism in Arabidopsis thaliana. Most recently, we have initiated studies of sphingolipids in the moss Physcomitrella patens. As the first land plants, mosses occupy an evolutionarily important niche. They also have a life cycle and tolerances to abiotic stresses that are different from those of flowering plants. The Physcomitrella genome has been sequenced and reliable methods of altering gene expression using RNA interference have been developed, allowing us to explore the consequences of disrupting specific steps in sphingolipid synthesis on moss growth and behavior.
