OsAOS1 and OsAOS2 negatively modulate the resistance of rice to BPH. (a,b) Mean number of gravid BPH females per plant (+SE, n = 10) on pairs of plants (WT versus as-aos1 (as1-3, as1-5, and as1-10) (a) or as-aos2 (as2-10, as2-20, and as2-58) (b), respectively), 1–48 h after plant pairs were exposed to 13 insects. Inserts: Mean percentage (+SE, n = 10) of BPH eggs per plant on pairs of plants as stated above. (c,d) Mean survival rates (+SE, n = 10) of BPH newly hatched nymphs fed on as-aos1, as-aos2, and WT plants, 1–12 days after the nymphs were placed on plants. (e) Mean concentrations (+SE, n = 5) of H₂O₂ in as-aos1, as-aos2, and WT plants that were individually infested by 12 gravid BPH females for 8 and 24 h. Asterisks indicate significant differences in as-aos lines compared with WT plants (* p < 0.05, ** p < 0.01, Student’s t-tests (a,b) or Tukey’s HSD post-hoc test (c–e)).
