Maternal and paternal genomes contribute equally to the transcriptome of early plant embryos.

Abstract excerpt

In animals, maternal gene products deposited into eggs regulate embryonic development before activation of the zygotic genome. In plants, an analogous period of prolonged maternal control over embryogenesis is thought to occur based on some gene-expression studies. However, other gene-expression studies and genetic analyses show that some transcripts must derive from the early zygotic genome, implying that the...
