Analysis of the expression profiles of nine genes related to phillyrin synthesis after 200 µM MeJA treatment for 0, 7, 12, and 24 h. (a). Relative expression levels of phillyrin biosynthesis genes in F. suspensa fruits are detected by qRT-PCR (0 h as 1). (b). Relative expression levels of phillyrin biosynthesis genes in F. suspensa leaves are detected by qRT-PCR (0 h as 1). The UKN1 + SDH + G6PD genes are used as the reference gene group to standardize the RNA samples for each reaction. All Statistical analyses of data had three biological repeats. Data are analyzed by SPSS, followed by Duncan’s honestly significant difference test at p < 0.05. All Statistical analyses of data had three biological repeats. FsPAL, phenylalanine ammonia-lyase gene; FsC3H, Coumarate 3-hydroxylase gene; Fs4CL, 4-coumarate CoA ligase gene; FsCCoAOMT, caffeoyl-CoA O-methyltransferase gene; FsCCR, cinnamoyl-CoA reductase gene; FsCAD, cinnamyl alcohol dehydrogenase gene; FsDIR, dirgent protein gene; FsOMT, O-methyltransferase gene; FsUGT, UDP-glycosyltransferase gene.
