Feeding-induced expression pattern of BSMT-like, MES1-like, S3H-like, and UGT74F2-like in mature leaves of Citrus sinensis. a Relative expression of BSMT-like. b Relative expression of MES1-like. c Relative expression of DMR6-like oxygenase. d Relative expression of UGT74F2-like. Expression levels were normalized using two references genes, β-Actin (accession number XM_026823249.1) and Elongation factor 1α (accession number XM_006488084). Data represent mean ± standard deviation (SD) of six biological replicates per treatment. Different letters indicate statistical differences between treatments at P < 0.05 using one-way ANOVA with Tukey’s post hoc test
