Fig. 1From: Transgenerational effect of mutants in the RNA-directed DNA methylation pathway on the triploid block in ArabidopsisInbreeding of RdDM osd1 mutants enhanced their ability to rescue the triploid block. a, c, e, g Seed abortion rates of homozygous osd1 or RdDM osd1 double homozygous mutants crossed as pollen donors to diploid wild-type plants. b, d, f, h The percentage of seeds that failed to germinate from each cross. Each filled circle represents 2–4 siliques from a single inflorescence pooled as one cross. Numbers on top represent total seed numbers. Asterisk represents statistically significant difference (p < 0.05) in comparison between the indicated groups. n.s, not significant.
