Parent-of-origin effect of the emf2a mutation during seed development. (A–C) Seed phenotypes at the maturation stage from self-pollinated emf2a-3/+ plants. Phenotypes were categorized as normal-looking (A), three abnormal types (B), and infertile (C). Scale bar = 2 mm. (D) Distribution of each seed phenotype depending on genotype from self-pollination of wild-type plants and plants carrying an emf2a mutation. Y-axis indicates the mutant allele and genotype of self-pollinated seeds. (E) Transmission rate of the emf2a allele in the F₁ progeny of reciprocal crosses between wild-type plants and plants carrying either emf2a-3 or emf2a-5. nd, not determined.
