Systemin

Description:

Systemin is a peptide hormone involved in plant defense mechanisms, particularly in response to herbivore attacks. It is primarily found in tomato plants and plays a crucial role in signaling pathways that activate the production of defensive compounds, such as proteinase inhibitors, which deter herbivores. Systemin is characterized by its relatively small size, typically consisting of a sequence of amino acids that allows it to function effectively in signaling. The CAS number 137181-56-7 specifically identifies this peptide, facilitating its recognition in chemical databases. Systemin operates through a receptor-mediated mechanism, triggering a cascade of physiological responses that enhance the plant's resilience against pests. Its discovery has significant implications for agricultural practices, as understanding its function can lead to the development of crops with improved resistance to herbivory, potentially reducing the need for chemical pesticides. Overall, systemin exemplifies the intricate biochemical interactions that underpin plant defense strategies in response to environmental stressors.
