Transcriptional activity of stilbene biosynthetic pathway genes and selected TF genes. Expression of the PAL (a), 4CL (b), STS (c), PMT (d), and ACC (e) genes in P. strobus cells after fungal elicitor treatment by qPCR analysis. f Transcriptional activity of two bHLH contigs (c126595_g1_i1 and c161886_g1_i1). g Transcriptional activity of two WRKY contigs (c48707_g1_i1 and c63840_g1_i1). h Transcriptional activity of two MYB contigs (c52919_g1_i1 and c133966_g3_i1). i Transcriptional activity of two MYB contigs (c130895, c134931, and c141277). The expression data were normalized to β-actin. The vertical bars in each column represent the mean ± SE based on three biological replicates
