The Evolution of Biochemical Diversity within the Solanaceae

Plants are master chemists that collectively synthesize thousands of metabolites. These metabolites fall into two distinct classes; primary metabolites that are common to most plant lineages such as sugars, amino acids and fatty acids together with specialized metabolites (formerly, secondary metabolites) that are often lineage or species specific. Specialized metabolites are chemically diverse and include broad classes of structurally distinct molecules such as terpenoids, flavonoids and alkaloids. Many specialized metabolites are implicated in plant responses to abiotic or biotic stress and can serve directly as toxins or repellants. Alternatively, specialized metabolites, particularly those associated with the color and aroma of flowers and fruits serve as attractants to pollinators or seed dispersing fauna. As such, specialized metabolites are often synthesized in specific organs or cell types at particular stages of development or in response to environmental perturbation. Humans have exploited plant specialized metabolites for millennia for use as flavorings, fragrances, medicines, and poisons.

The Solanaceae (nightshade family) is a large and diverse family of approximately 3000 species that occupy varied ecological niches including species that thrive in tropical rain forests, at high altitudes in the mountain ranges of the Andes, and in desert environments. In addition, several Solanaceae species are important crop plants including potato, tomato, pepper, eggplant, tobacco and petunia. The Solanaceae family also exhibits tremendous phenotypic variation, including prolific diversity of specialized metabolites that often show restricted distribution to particular genera or species, or even to specific accessions within a species. This chemical diversity is fueled by rapid gene evolution that generates copy number variation leading to relaxed selection and subsequent neofunctionalization. We are utilizing an integrated approach involving genomics, metabolite profiling, gene-silencing biochemical analyses and synthetic biology to investigate the biosynthesis and evolution of specialized metabolite pathways within the Solanaceae. Current research is focused on the synthesis of defense compounds such as terpenes and acylsugars in the glandular trichomes and the biosynthesis of the medicinally important tropane alkaloids that occurs within the roots of selected members of the Solanaceae family.
