Who's related to whom? Recent results from molecular systematic studies

摘要: Similarities among model systems can lead to generalizations about plants, but understanding the differences requires systematic data. Molecular phylogenetic analyses produce results similar traditional classifications in grasses (Poaceae), and relationships cereal crops are quite clear. Chloroplast-based phylogenies for Solanaceae show that tomato is best considered as a species of Solanum, closely related potatoes. Traditional Brassicaceae misleading with regard true data only now beginning clarify situation. also being used revise our view flowering plant families.
