Polymalonate
WebJan 1, 2015 · Lichens have evolved diverse biosynthetic pathways mainly polymalonate, shikimic acid and mevalonic acid pathways to produce this diversity of compounds. It has been proved that among the diverse group of secondary metabolites , esters, depsides and depsidones are precursors of orcein, the coloured compound formed in lichen dyes. Weba: acetate-polymalonate pathway; b: shikimic acid pathway: c: mevalonic acid pathway. Bolded: major substances of the chemosyn drome Cultures of both species produced and secr eted the phenalenone myeloconone C to the culture media, which probably have allelopathic properties similar to those exhibited by plant phenalenones [34].
