Solanaceae Source

A global taxonomic resource for the nightshade family

Next SOL Seminar Online will be presented by Peter Poczai on Plastid Genome Evolution in Solanaceae: past, present and future

Abstract. Stroll through a flowered park, dip into a cool summer lake, or hike in a dense forest and you will find yourself in good company. I am talking about plants, of course, but more specifically about chloroplasts—the factories of photosynthesis and hubs of countless crucial biochemical reactions. Yes, chloroplasts (and plastids as a whole) are one awesome eukaryotic organelle. Their pigments alone provide the world with much of its beautiful and mellifluous colours, not to mention their clever and life-sustaining ability to convert carbon dioxide and water into oxygen and sugar through a quantum mechanical process. These compact cellular organelles are preserving well in dried plant material (herbaria) for centuries allowing us to investigate important evolutionary biological questions in the postgenomic era. The megadiverse plant family Solanaceae has long been connected to chloroplast genome research since the publication of the first complete nucleotide genome sequence of tobacco (Nicotiana tabacum). High throughput sequencing technologies are providing us the opportunity to explore plastid genome evolution, adaptation and other important questions. Solanaceae plastid genomes sequenced so far showed a typical quadripartite structure without specific structural rearrangements, however, large plastid genomes with extensive inverted repeat boundary expansions exist in Solanaceae. These could have interesting biological implications in future plastid genome research in Solanaceae.
