Many biologists agree that a phylogenetic tree of relationships should be the central foundation of research in many areas of biology. Comparisons of plant species or gene sequences in a phylogenetic context can provide the most significant information on biology. This important achievement is now evident to researchers in various fields, including ecology, molecular biology and physiology (see recent articles in Plant physiology, e.g. Hall et al., 2002a; Doyle et al., 2003) . There are many examples of the importance of a phylogenetic framework for various fields of plant research (for a review, see Soltis and Soltis, 2000; Daly et al., 2001). An obvious example is the value of placing model organisms in the appropriate phylogenetic context to gain a better understanding of models and evolutionary processes. The fact that the tomato (Lycopersicon esculentum) and other species of this small genus are actually integrated into a well-marked Solanum subclade (and, therefore, are more appropriately called Solanum species; the tomato has been renamed Solanum lycopersicon; for example Spooner et al., 1993; Olmstead et al., 1999) is a powerful statement which is important for geneticists, molecular biologists and plant breeders in that it points to a few close relatives of S. lycopersicon (on a genus of several hundred species) as focal points for comparative genetic / genomic research and for crop improvement. The snapdragon (Antirrhinum majus) was historically part of a broadly defined Scrophulariaceae, a family which is now known to be grossly polyphyletic (i.e. not a single clade). Phylogenetic studies indicate that the Scrophulariaceae should be divided into several families (Olmstead et al., 2001), and the snapdragon and its closest relatives are part of a clade recognized as the family of Plantaginaceae.
