Validation of reference genes and tissue-specific analysis of β-pinene synthase expression between CRD, CZ and whole cross-section tissues. (A) Relative mRNA abundance of candidate reference genes normalized to RNA concentration. TIF: Translation initiation factor; ELF: Elongation factor; TUB: Tubulin α-subunit. (B) Relative transcript abundance of β-pinene synthase in different tissue types relative to TIF expression. Error bars represent the standard error of three biological replicates.
