Abstract

Naturally occurring quinones are well characterised with respect to their potent biological activities. Specifically, they possess antitumor, antiinflammatory, antiparasitic, antimicrobial, insecticidal, fungicidal and herbicidal activities. Quinones are known to inhibit electron transport involved in photosynthesis and mitochondrial respiration. Quinone-based fungicides are classified as ”organic fungicides” and are known multisite inhibitors. This may be advantageous in the prevention of resistance development in fungal pathogens. Similarly, quinone-based natural herbicides were also described with multisite inhibitors. We have studied two unusual groups of root-produced quinones in Sorghum spp. (sorgoleones) andEchium spp. (shikonins) that may confer competitive advantage to plants producing them in high concentration.
