Expression of NlGr25 induced by various rice cultivars. NlGr25 mRNA abundance was measured by quantitative real-time PCR. Total RNA was extracted from BPH at 3, 6, 12 and 24 h after feeding from different rice cultivars. TN1: Taichung Native 1, a BPH susceptible variety; IR36: International Rice 36, a BPH-resistant variety contains resistance gene bph2; IR56: International Rice 56, a BPH-resistant variety contains resistance gene Bph3. Data are shown as the means ± SE of three replicates. Significant differences between two treatments are marked with an asterisk (t-test), *, at the 0.05 level; **, at the 0.01 level
