Abstract

The importance of gibberellin (GA) in vegetative and reproductive development has been known for some time. Recent studies have uncovered new roles of GA in leaf differentiation, photomorphogenesis and pollen-tube growth. Significant contributions to our understanding of GA-regulated morphogenesis include the identification of upstream regulators of GA biosynthesis, the elucidation of the function of GA signaling components, and the isolation of downstream targets. In addition, the mechanisms of interactions between GA and other hormone pathways are beginning to be revealed at the molecular level.

摘要

赤霉素（GA）在营养生长和生殖发育中的重要性已为人所知有一段时间了。最近的研究揭示了GA在叶片分化、光形态建成和花粉管生长中的新作用。对我们理解GA调控的形态发生有重要贡献的包括GA生物合成上游调节因子的鉴定、GA信号转导组分功能的阐明以及下游靶标的分离。此外，GA与其他激素途径之间相互作用的机制也开始在分子水平上被揭示。
