Evolution and development of virtual inflorescences

The architecture of inflorescences diverged during the evolution of distinct plant families by mechanisms that remain unknown. Using computer modeling, Przemyslaw Prusinkiewicz and colleagues established a single model for the development of distinct inflorescences. Selection restricts inflorescence evolution to high fitness paths that vary with climate and other factors that influence reproductive success - explaining why some evolutionary transitions are more likely than others. This model presents an important framework for future plant 'evo-devo' research.
