Transient expression of PbbZIP4 in the scentless P. aphrodite flowers induced the production of monoterpeneoids. (A) Selected ion (m/z 136) GC-MS profiles of volatiles detected from GUS- and PbZIP4-expression flowers. The peak with a dot indicates α-terpineol. The products were confirmed by comparing the mass spectra of the indicated peak with the one of the library hit. (B) The levels of volatiles emitted from the flowers infiltrated with GUS (gray) and PbbZIP4 (dark-gray). (C) Relative expression levels of PbbZIP4 of the flowers infiltrated with GUS (gray) and PbbZIP4 (dark-gray). Error bars on each column represent ± SE from three biological replicates.
