Abstract: Plants belong to the most successful organisms on earth. They are able to recognize, respond to and interact with their (a)biotic environment. Among others, plants react to insect herbivore attack, thereby employing an array of defense strategies. A prerequisite for the onset of such appropriate reactions is the perception of insect-derived cues followed by well-coordinated local and systemic signaling processes. Ca2+-ions and jasmonate phytohormones have been implicated as key messenger in many plant signaling pathways, and step by step we learn more about their specific roles in the regulation of defense against herbivory. The same holds true for systemic signals that can be detected within the plant. Some plant taxa were able to turn the sword around: They became carnivorous. Although known for 150 years, our knowledge concerning the physiology, biochemistry, and molecular biology of plant carnivory is still limited. Only in recent years, -omics analyses have been started, signaling pathways have been identified. I will present data about prey recognition, signaling, composition of digestive fluids concerning proteins as well as secondary metabolites; finally I will discuss general aspects of the plant carnivorous syndrome with respect to plant defense mechanisms.
The Halle Plant Science Colloquium (HPSC) is an interdepartmental colloquium of Institutions of the Martin-Luther-University working on any aspect of functional plant biology.
