Conservation and diversity in flower land.

During the past decade, enormous progress has been made in understanding the molecular regulation of flower development. In particular, homeotic genes that determine the identity of the floral organs have been characterised from different flowering plants, revealing considerable conservation among angiosperm species. On the other hand, evolutionary diversification has led to enormous variation in flower morphology. Increasing numbers of reports have described differences in the regulation, redundancy and function of homeotic genes from various species. These fundamentals of floral organ specification are therefore an ideal subject for comparative analyses of flower development, which will lead to a better understanding of plant evolution, plant development and the complexity of molecular mechanisms that control flower development and morphology.
