Unformatted text preview: Oligosaccaharin Systemin Systemin is a small peptide found in wound tissue. It may stimulate defense activities as the signal molecule (ligand) that activates the signal transduction pathways that include the jasmonates. Jasmonates Jasmonates are a group of fatty acid derivatives. They appear to have a role in seed germination, root growth, and the storage of protein (especially in seeds). Jasmonates synthesized in response to signal molecules produced in wound areas are involved in the signal transduction pathways that result in secondary metabolites (protease inhibitors) that poison the predator, or synthesis of volatile molecules that attract the predators predators. (We will discuss plants and their defenses at the end of this unit.)...
