thumb|Chemical structures of karrikins (KAR1, KAR2, KAR3, and KAR4)
Karrikins are a group of plant growth regulators found in the smoke of burning plant material. Karrikins help stimulate seed germination and plant development because they mimic a signaling hormone known as strigolactone. Strigolactones are hormones that help increase growth of symbiotic arbuscular mycorrhizal fungi in the soil, which enhances plant growth and leads to an increase in plant branching.
