GR24 is a strigolactone that stimulates germination of root parasitic weeds and hyphal branching of symbiotic arbuscular mycorrhizal fungi, and regulates shoot outgrowth. GR24 stimulates the expression of DRM splicing variants and inhibits root branching in 5-day-old Arabidopsis thaliana (L.) Heynh. seedlings. GR24 has anti-inflammatory activity, inhibiting the release of cytokines by blocking NF-kB and MPAK signalling pathways.
