Back Cover: Metabolomics Enables the Structure Elucidation of a Diatom Sex Pheromone (Angew. Chem. Int. Ed. 3/2013)
Asexual division of the diatom Seminavis robusta (see picture) results in size reduction owing to the restriction of the biomineralized cell wall. Below a critical size, diatoms must find a suitable partner for mating and sexual reproduction. In their Communication on page 854 ff., G. Pohnert et al. describe metabolomic studies in which l-diproline was identified as the first diatom pheromone.
