Two plant species invent the same chemically complex and medically interesting substance
The elucidation of the biosynthetic pathway of #ipecacuanha #alkaloids shows how two distantly related plant species could develop the same substance independently

EurekAlert!Two plant species invent the same chemically complex and medically interesting substanceThe biosynthesis of the great variety of natural plant products has not yet been elucidated for many medically interesting substances. In a new study, an international team of researchers was able to show how ipecacuanha alkaloids, substances used in traditional medicine, are synthesized. They compared two distantly related plant species and were able to show that although both plant species use a comparable chemical approach, the enzymes they need for synthesis differ and a different starting material is used. Further investigations revealed that the biosynthetic pathways of these complex chemical compounds have developed independently in the two species. These results help to enable the synthesis of these and related substances on a larger scale for medical use.

"They identified the bloom-forming #Pelagophyceae algae as potentially abundant, important producers of a compound called #DMSP... this is the main source of a #climate active gas called #dimethylsulfide (#DMS), which is known as the smell of the seaside."
