* In crops, variations in the genes for these enzymes may have arisen from duplication and adaptation for specialized functions, while the model plant Brachypodium distachyon has a simpler gene set related to gibberellin biosynthesis, including one ent-CPS gene and four KS-like genes.
* Detailed studies revealed that BdCPS and BdKS1 in B. distachyon are crucial for gibberellin production, whereas BdKSL2 and BdKSL3 likely
