LjEβOS transcripts and (E)-β-ocimene emissions in L. japonicus plants in response to spider mite infestation or mechanical wounding. A, Northern analysis of transcripts in the L. japonicus shoots exposed to spider mites or wounded mechanically for 0, 1, 6, and 24 h. B, Volatiles were collected over 2 h at time points, 1 to 3 h, 6 to 8 h, and 24 to 26 h from the headspace of L. japonicus exposed to spider mites or wounded mechanically and subjected to GC-MS. Data represents the mean ± se (n = 4–9, ion intensity of (E)-β-ocimene per gram fresh weight). Untreated plants served as control. A bar with asterisk is significantly different from the untreated control within each sampling interval (Dunnet's test at the 0.05 level).
