Genes suppressed by Spodoptera littoralis oral secretions (OS) Genes induced by wounding after 6 h or 24 h were selected from microarray data (expression ratio >1.5 and P value <0.05, Student’s t test). Then, genes suppressed by Spodoptera littoralis OS were selected if the expression ratio in response to wounding was significantly larger than the expression ratio in response to OS treatment. Expression ratios (±SE) are the average of six (wounding) and three (OS) independent experiments. Genes in bold were selected for further experiments. P values refer to the comparison between wounding and OS treatment (Student’s t test).
