Silencing NappHS reduces the number of seed capsules produced in two accessions of N. attenuata. Mean ± se number of mature seed capsules of 12 to 15 (A, top) wild-type (WT, black bars), IRsys line 1 (white bars), and IRsys line 2 (gray bars) plants of the AZ (left section) and UT (right section) accessions. Mean ± se seed number per capsule of the first four to five ripe self-pollinated capsules per plant (n = 12) of each genotype (A) and of emasculated and hand-pollinated flowers (B). Different letters indicate significant differences from wild-type plants as determined by ANOVA followed by Bonferroni-corrected post-hoc test.
