Strigolactones are the most recent class of fytohormones, which were originally recognized as stimulators of seed germinators of parasitic weeds Striga and Orobanche spp. They also stimulate symbiosis of plants with arbuscular mycorhizal fungi. Their functions in plants and biosynthesis are described. The isolated natural strigolactones and their main synthetic derivatives are listed. Attention is focused on their mechanism of action and structure-activity relationships.
