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.

花地的保护和多样性。

在过去的十年中，在理解花卉发育的分子调控方面取得了巨大进展。特别是，已经从不同的开花植物中鉴定了确定花器官身份的同源基因，揭示了被子植物中相当大的保守性。另一方面，进化的多样化导致了花形的巨大变化。越来越多的报告描述了来自各种物种的同源基因在调节，冗余和功能方面的差异。因此，花卉器官规格的这些基础知识是比较比较好的花卉发育分析的理想主题，这将使人们更好地理解植物的进化，植物发育以及控制花卉发育和形态的分子机制的复杂性。
