Fig. 10From: Genomic characterization of WRKY transcription factors related to secoiridoid biosynthesis in Gentiana macrophyllaAnalysis of the gene expression involved in secoiridoid biosynthesis in MeJA-treated seedlings of G. macrophylla (0 h, 6 h, 12 h and 24 h) tested by RT–qPCR. The CK (the seedling of G. macrophylla not treated with MeJA) was used as the blank control. The asterisks (*) represent significant differences (*, P < 0.05; **, P < 0.01; ***, P < 0.001; and ****, P < 0.0001)Back to article page
