The invention discloses a PgRb1-057-001 gene, the base sequence of which is shown in SEQ ID NO.1 in the sequence table; the application of the PgRb1-057-001 gene in improving ginsenoside Rb1; the present invention will overexpress PgRb1‑057‑001 gene-positive hairy roots were propagated in a single root system, and the Rb1 content in the transgenic positive hairy roots changed significantly, and the Rb1 content increased, reaching a maximum of 9.25 mg/g . The biosynthesis of ginsenoside Rb1 has a promoting effect and at the same time controls the biosynthesis of Rb1 saponin. |
