Spatial and temporal expression profiles of TkSQS, TkSQE and TkOSC1 mRNA in wild‐type Taraxacum koksaghyz plants determined by qRT‐PCR and temporal isoprenoid levels in wild‐type T. koksaghyz plants. The corresponding mRNA levels were normalized against the constitutive genes encoding elongation factor 1α (TkEF1α) and ribosomal protein L27 (TkRP) from T. koksaghyz. Data are means ± standard errors of three pools, each consisting of three independent wild‐type plants. (a) TkSQS1 and TkSQE1 and (b) TkSQS2 and TkSQE2–4 mRNA levels in latex, roots, leaves, peduncles, and flowers of 12‐week‐old wild‐type T. koksaghyz plants. (c) TkSQS1 and TkSQE1 mRNA levels in latex of 8‐ to 20‐week‐old wild‐type T. koksaghyz plants. (d) Squalene and 2,3‐oxidosqualene levels in roots of 8‐ to 20‐week‐old T. koksaghyz plants. (e) TkOSC1 mRNA levels in the latex of 8‐ to 20‐week‐old wild‐type T. koksaghyz plants. (f) Sterol and pentacyclic triterpene levels in roots of 8‐ to 20‐week‐old wild‐type T. koksaghyz plants
