Carrots and other Apiaceous species produce polyacetylenic lipids, often in the form of falcarins such as falcarinol and falcarindiol, C17 aliphatic compounds with multiple triple bonds thought to be derived from linoleic acid (C18:2). These falcarins are known to have potent antibiotic activities against human pathogens as well as anticancer activities. Although they have been described in primary literature for decades, their role in plant disease resistance and the genetic basis of their biosynthesis remain poorly understood. Results on the biosynthesis and functional role of falcarins in defense against S. sclerotiorum and other necrotrophic pathogens will be presented.
