GR24 is a synthetic strigolactone and plant growth regulator that stimulates germination of parasitic weeds and hyphal branching of symbiotic mycorrhizal fungi, and regulates shoot outgrowth. GR24 stimulates the expression of DRM splicing variants and inhibits root branching in Arabidopsis thaliana seedlings. GR24 has anti-inflammatory activity, inhibiting the release of cytokines by blocking NF-kB and MPAK signalling pathways.
