Os6PGDH1 positively regulates rice resistance to BPH. (A,B) Mean number (+SE, n = 10) of gravid BPH females per plant on pairs of plants (WT versus oe-15 (A) and oe-39 (B)). Insert: Mean number (+SE, n = 10) of eggs per plant on pairs of plants as stated above. Asterisks indicate significant differences between oe6PGDH and WT plants (* p < 0.05, ** p < 0.01, Student’s t-test). (C) Mean hatching rate (+SE, n = 10) of eggs on oe6PGDH plants and WT plants. (D) Mean number (+SE, n = 30) of eggs laid by one pair of BPH female and male adults that emerged from oe6PGDH or WT plants. Asterisks indicate significant differences in oe6PGDH lines compared with those in WT plants (one-way ANOVA followed by Duncan’s multiple range test, p < 0.05).
