Does the MEP pathway feed ginsenoside production?
Open access · cc by · source: Europe PMC
Transcriptomics implicates the chloroplastic MEP pathway—highlighting IspD—in ginsenoside biosynthesis beyond the classic MVA route.
Key findings
MEP pathway contributes to ginsenoside biosynthesis; IspD predicted as a key MEP enzyme; tissue patterns match ginsenoside distribution.
Methodology
Profiled Panax ginseng transcriptomes across tissues and related MEP/MVA pathway expression to ginsenoside patterns.
Limitations
Does not alone prove industrial-scale pathway engineering yields.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
MEP pathway contributes to ginsenoside biosynthesis; IspD predicted as a key MEP enzyme; tissue patterns match ginsenoside distribution.
Evidence for the claim as stated.
RNA-seq can be joined to genetics and to metabolites, still without proving causation. In 77 Yoruba LCLs, inter-individual methylation tracked genotypes and correlated with RNA-seq expression; in Panax ginseng, MEP-pathway expression patterns were taken to contribute to ginsenoside biosynthesis with IspD predicted as a key enzyme.
Evidence for the claim as stated.
