| description | The study highlights the influence and signal transduction mechanism of postharvest UV-B on the production of Rg<sub>1</sub> in <i>Panax quinquefolius</i> roots during the drying process. The results showed that postharvest UV-B irradiation induced generation of nitric oxide (NO), jasmonic acid (JA), and ginsenoside Rg<sub>1</sub> of <i>P. quinquefolius</i> roots. The UV-B-induced increase of Rg<sub>1</sub> was suppressed by NO-specific scavenger (cPTIO) and NOS inhibitors (PBITU), JA synthesis inhibitor (SHAM), and JA synthesis inhibitor (PrGall), indicating that NO and JA played essential parts in UV-B-induced Rg<sub>1</sub>. External NO inhibitors treatment inhibited UV-B-induced accumulation of NO and JA, which suggested that NO was located upstream of the JA signal pathway. NO-caused Rg<sub>1</sub> was inhibited by SHAM and PrGall, implying JA participated in transmitting signal NO to Rg<sub>1</sub> accumulation. In other words, NO mediated the postharvest UV-B-induced Rg<sub>1</sub> accumulation by the JA-dependent pathway in <i>P. quinquefolius</i> roots during the drying process, which helps us understand the underlying mechanisms involved in UV-B-induced Rg<sub>1</sub> production and provides information helpful for <i>P. quinquefolius</i> production. |
