Temporal-spatial expressions of the six ginsenoside biosynthesis candidate PgCYP genes and the previously cloned ginsenosides biosynthesis genes. CYP716A53v2_1, CYP716A52v2_3, CYP716A47_1, DS_1, DS_3, β-AS_1, β-AS_6, CAS_11, CAS_21, CAS_22, CAS_23 SS_1, SE2_1, SE2_4, FPS_22 and UGT71A27_2, are previously cloned ginsenosides biosynthesis genes, while the six ginsenoside biosynthesis candidate PgCYP genes were identified in this study. The suffix of each gene, such as ā_1ā and ā_3ā to DS, indicates the transcript of the gene. (A) Expressions of the genes in the roots of differently-aged plants. (B) Expressions of the genes in different tissues of a four-year-old plant.
