Effects of maternal NRPD1-siRNA target genes on seed size. (A) Diagrams of AGL40 and AGL91 showing T-DNA insertion sites. (B) Relative expression levels (REL) of AGL40 and AGL91 in T-DNA insertion lines (mean ± SEM; P = 0.01). *P = 0.05; **P = 0.01. (C) Mature seed images in Wt, agl40, and agl91 lines. (D) Seed weights in Wt, agl40, and agl91 lines (mean ± SEM; P = 0.05). (E) Mature seeds in three independent Wt^SUP:GL40 transgenic lines and one control (transformed with the vector alone) under the endosperm-specific promoter from AT5G27880. (F) RELs of AGL40 in three Wt^SUP:GL40 lines and one control (mean ± SEM; P = 0.01). (G) Seed weights in three Wt^SUP:GL40 lines (n = 3 × 500 seeds per line) and one control (P = 0.05). (Scale bars: 0.5 mm for all images.)
