In a desire to study the relationships between plant metabolic systems and their evolutionary diversity, by looking at a phylogenetic tree of diverse species, it is difficult to deduce which systems of metabolism and plant morphological types are related. The genome is also regulated and difficult to comprehend or analyze. It seems like a type of a genetically variable set of older or basic genes could act as a marker in how they appear. Metabolism and organic chemistry are very complicated too, so an analytical approach could be useful as a tool.
