Comparative transcriptome analysis provides novel insights into the seed germination of Panax japonicus, an endangered species in China.

ABSTRACT: Panax japonicus, an endangered species in China, is usually used as a traditional medicine with functions of hemostasis, pain relief, and detoxify. However, the seeds of P. japonicus are hard to germinate in natural conditions, and the molecular events and systematic changes occurring in seed germination are still largely unknown. In this study, we compared the seeds in different germination stages in terms of morphological features, antioxidant enzyme activities, and transcriptomics. The results indicated that sand storage at 25℃ for 120 d effectively released the seed dormancy of P. japonicus and promoted the seed germination. Moreover, sand storage treatment increased the antioxidant capacity of P. japonicus seeds through increasing the activities of SOD, POD, and CAT. The RNA-seq ident
