生长素在植物生长发育的许多方面都有着重要的作用，包括花的发育。然而，生长素在花发育中的确切作用一直没有得到很好的定义，直到最近的生长素生物合成突变体的鉴定。生长素是花原基发生所必需的，生长素生物合成、极性运输或信号转导的中断导致花的形成失败。生长素在确定花器官的数量和身份方面也起着至关重要的作用。进一步分析生长素途径与已知花发育基因之间的关系，将为植物器官发生和花型形成机制提供重要信息。
Auxin has long been implicated in many aspects of plant growth and development including flower development. However, the exact roles of auxin in flower development have not been well defined until the recent identification of auxin biosynthesis mutants. Auxin is necessary for the initiation of floral primordia, and the disruption of auxin biosynthesis, polar auxin transport or auxin signaling leads to the failure of flower formation. Auxin also plays an essential role in specifying the number and identity of floral organs. Further analysis of the relationship between the auxin pathways and the known flower development genes will provide critical information regarding mechanisms of organogenesis and pattern formation in plants.
