Indole priming induced differential expression of anti-oxidant genes.

qRT-PCR analysis of four anti-oxidant enzyme encoded genes in detached maize leaves as described in Fig 5. Primed (red) and non-primed (blue) samples were collected at 0, 3, 6, 12, 24 and 48 h after punch inoculation of F. graminearum spores. Ef1α was used as the endogenous control. Asterisks indicate significant difference (Student’s t-test, *PPPn = 3).
