Segetalin B is a bioactive cyclic peptide primarily studied for its potential role in plant physiology, particularly in relation to growth regulation and defense mechanisms. It has shown phytoestrogenic activity, meaning it can influence hormonal pathways in plants, potentially affecting development and stress responses. Research also explores its interaction with plant signaling systems, which may lead to applications in enhancing crop resilience or modulating growth patterns. Due to its bioactive nature, Segetalin B is of interest in agricultural science for developing natural growth promoters or eco-friendly pest management strategies. However, practical applications are still largely confined to experimental research.
