    Abstract:
    Gibberellin is one of the most important plant growth regulators, and widely used in agricultural production. However, the high cost of gibberellins production is restricting its efficient application. In recent years, biotechnological innovations have improved the synthesis of gibberellin. Gibberellin biosynthesis requires various enzymes. Current research focuses on the biosynthetic mechanisms of gibberellin and the metabolic engineering techniques to improve the production of gibberellin. This paper reviews the current research on gibberellin biosynthesis pathway, the key and enzymes environmental factors involved, and the metabolic regulation of gibberellin in Gibberella fujikuroi, summarizes the application of metabolic regulation in gibberellin biosynthesis, to provide the basis for achieving stable gibberellins production. 赤霉素是最重要的植物生长调节剂之一，在农业生产中得到越来越广泛的应用，具有广阔的市场前景，但其工业化的高生产成本严重制约着它的广泛应用。近年来，利用生物技术提升赤霉素产量日益成为研究热点。赤霉素生物合成是多种酶协同作用的过程，阐明赤霉素的生物合成机制，利用代谢工程策略调控代谢流量，对提高赤霉素产量至关重要。文中综述了当前藤仓赤霉菌赤霉素生物合成途径、关键酶、环境因素、代谢流调控等方面的研究进展，在代谢调控方面进行了展望，以期为实现赤霉素稳产高产提供思路。.
