Abstract:
Taking the fresh roots，stems，leaves，and flowers of ‘Ningqi 1’ and ‘Ningqicai 1’ sampled in summer as the experimental materials,high-performance liquid chromatography (HPLC) and quantitative real-time polymerase chain reaction (qRT-PCR) were utilized to investigate melatonin contents and the expression profiles of melatonin biosynthetic genes across different organs，in order to provide reference for the subse quent research on the synthesis of melationin in Lycium barbarum L.and the exploration of its medicinal value.The results showed that the melatonin content in each organ of ‘Ningqicai 1’ was significantly higher than that of ‘Ningqi 1’.For both cultivars，the melatonin content followed the descending order of flower>leaf>stem>root.Additionally，the four biosynthetic genes，namely TDC,T5H,COMT00，and COMT01，were ubiquitously expressed in roots，stems，leaves，and flowers.
