A decaploid pitcher plant genome reveals a novel role for recessive subgenomes

Genomic polyploidy is prevalent in the plant kingdom, giving rise to dominant and recessive subgenomes. We show that the recessive subgenomes of the pitcher plant Nepenthes gracilis had a crucial role in the acquisition of novel genes with species-specific function such as dioecy and carnivory.
