Improving the accumulation of 18α-and 18β-glycyrrhizins by over-expressing GuHMGR, GuSQS1, and GuBAS genes in Glycyrrhiza uralensis

Over-expression of the GuHMGR, GuSQS1, and GuBAS genes enhance the accumulation of 18α- and 18β-GC in the roots and rhizomes of G. uralensis. We hope this work can lay a foundation for the molecular breeding research of G. uralensis and improving the quality of the roots and rhizomes of G. uralensis cultivars.
