The low availability of phosphorus has become a common problem worldwide. Phosphorus is essential for phenotypic morphology and ginsenoside synthesis. However, the effects Pi stress on ginseng phenotype synthesis remain unclear. Phenotypic analyses transcriptomics revealed construction regulation differential genes involved in physiological metabolism under low-Pi stress. Root length stem were found to be significantly inhibited by phosphate-deficiency half-phosphate (HP) no-phosphate (NP) treatment groups; however, number fibrous roots, which are regulated phytohormones, was increase. In leaves, indexes stress, superoxide anion (221.19 nmol/g) malonaldehyde (MDA) (0.05 μmol/min/g), reached maximum level. Moreover, chlorophyll fluorescence images content further confirmed inhibition photosynthesis A total 579 210 differentially expressed (DEGs) shared between NP phosphate (TP) HP TP, respectively, only 64 DEGs based two comparisons. These mainly related transporters (PHTs), ginsenosides.
