植物激素受到严格的调控，以响应环境和发育信号。长期以来，人们一直推测激素的生物合成广泛存在于植物器官中，激素在发育中的器官原基中复杂的时空调节是通过运输和信号感知实现的。然而，最近对生长素和细胞分裂素生物合成至关重要的基因的鉴定表明，局部的激素生物合成在器官的生长和模式中也起着重要的作用。
Plant hormones are tightly regulated in response to environmental and developmental signals. It has long been speculated that biosynthesis of hormones occurs broadly in plant organs and that intricate, spatiotemporal regulation of hormones in developing organ primordia is achieved through transport and signal perception. However, recent identification of genes crucial for biosynthesis of auxin and cytokinin reveals that localized hormone biosynthesis also plays an important role in organ growth and patterning.
