Technological progress in plant genomics enables the generation of high quality genome sequences for numerous plant species. While the generation of genome sequences is turning into a routine task, production of a high quality annotation remains a challenge. Especially the assignment of functional descriptions to predicted gene models is necessary to understand plant genomes. We developed several tools to support the identification of candidate genes involved in biosynthesis pathways and their regulation. This automatic annotation facilitates comparative studies across many plant species and in-depth investigations of specific traits. Of particular interest are specialized metabolite biosynthesis pathways due to the enormous biochemical diversity of natural plant products and the wide range of applications. It is possible to compare the presence and locations of genes across many plant species to gain insights into the evolution of biosynthesis pathways. The anthocyanin biosynthesis is one such pathway with products that are well known for their contribution to flower coloration. Anthocyanins are of interest in biotechnological application, have nutritional benefits, and serve as a model system for pigment evolution in the Caryophyllales. A combination of comparative transcriptomics and genomics revealed insights into the molecular mechanisms behind the phylogenetic distribution of anthocyanins in the Caryophyllales. Similar approaches are deployed to characterize the diversity of intracellular anthocyanin transport which is a largely unexplored aspect of anthocyanin biology
