Chemistry of Strigolactones, Key Players in Plant Communication

Today, the use of artificial pesticides is questionable and the adaptation to global warming is a necessity. The promotion of favorable natural interactions in the rhizosphere offers interesting perspectives for changing the type of agriculture. Strigolactones (SLs), the latest class of phytohormones to be discovered, are also chemical mediators in the rhizosphere. We present in this review the diversity of natural SLs, their analogs, mimics, and probes essential for the biological studies of this class of compounds. Their biosynthesis and access by organic synthesis are highlighted especially concerning noncanonical SLs, the more recently discovered natural SLs. Organic synthesis of analogs, stable isotope-labeled standards, mimics, and probes are also reviewed here. In the last part, the knowledge about the SL perception is described as well as the different inhibitors of SL receptors that have been developed. Natural strigolactones (SLs), plant hormones and allelochemicals are reviewed here as analogs, mimics and probes developed to study their biological activities. All stable isotope-labeled SLs, essential for the quantification of their corresponding SLs are also reviewed. The syntheses of all these compounds are presented. The knowledge about the perception of SL is reviewed as well as different inhibitors of their receptors. image
