Bioprocess of Gibberellic Acid by : The Challenge of Regulation, Raw Materials, and Product Yields.

Gibberellic acid (GA) is a tetracyclic diterpenoid carboxylic acid synthesized by the secondary metabolism of . This phytohormone is widely studied due to the advantages it offers as a plant growth regulator, such as growth stimulation, senescence delay, flowering induction, increased fruit size, and defense against abiotic or biotic stress, which improve the quality and yield of crops. Therefore, GA has been considered as an innovative strategy to improve agricultural production.
