rac-GR24: A Standard Tool for Strigolactone Research

Strigolactones are an important class of plant hormones that regulate plant growth and mediate interactions with the surrounding environment. They are widely studied in plant physiology, agronomy, symbiosis with microorganisms (such as the induction of arbuscular mycorrhizal fungi), weed science, and agrochemical development.

Representative biological functions include the following:

• Inhibition of shoot branching: Conserves energy and promotes preferential growth of the main stem.
• Promotion of root development: Enhances nutrient uptake efficiency by stimulating the formation of root hairs and lateral roots.
• Induction of symbiotic fungi (arbuscular mycorrhizae): Attracts symbiotic fungi to plant roots and facilitates phosphorus uptake.
• Stimulation of parasitic plant germination: Induces the germination of parasitic plants such as Striga and Orobanche.

rac-GR24 is a well-established synthetic analog that mimics natural strigolactones and is widely used as a standard compound in plant hormone research. As a practical alternative to natural strigolactones, which are difficult to obtain, rac-GR24 serves as a powerful tool for artificially replicating strigolactone-mediated plant physiological processes.^1,2,3)
