Webbiosynthesis in plants, especially from non-model plant species (Osbourn & Lanzotti, 2009). In this study we performed global expression analysis by RNA-Seq and compared the transcriptomes of tissues and species that accumulate or do not accumulate alkamides. Differentially expressed candidate genes were identiﬁed and based on their nature, an Genomic studies suggest strong homology with Ped genes, which encode the production of pederins, structurally similar compounds synthesized by bacterial endosymbionts of Paederus beetles. This suggests that onnamide A is actually the product of bacterial endosymbionts of the marine sponges from which the compound was first isolated.
