Mean (±sd) expression ratios from
microarrays with eight replicate cDNA spots with partial sequences of
genes mediating N. attenuata's oxylipin cascade
(lipoxygenase [LOX], HPL, AOS, and α-DIOX) hybridized with
fluorescently labeled probes derived from M. sexta-attacked
or control N. attenuata plants (harvested 2, 6, 12, or
24 h after the start of attack). Shaded area represents
arbitrarily defined zone of nonsignificant changes in expression.
