Bikinin is primarily utilized in plant biology research to study the brassinosteroid signaling pathway. It acts as an inhibitor of the BIN2 kinase, a key negative regulator in this pathway, allowing scientists to explore the role of brassinosteroids in plant growth and development. By modulating this pathway, researchers can investigate its impact on processes such as cell elongation, division, and stress responses. This makes bikinin a valuable tool for advancing understanding of plant physiology and potentially improving crop resilience and productivity.
