Stilbenoids are secondary products of heartwood formation in trees that can act as phytoalexins. In chemical terms, they are hydroxylated derivatives of stilbene. In biochemical terms, they belong to the family of phenylpropanoids and share most of their biosynthesis pathway with chalcones. An alternative bacterial stilbenoid ketosynthase-directed pathway exists in bacterial symbionts of nematodes.
