WebJan 28, 2024 · First, organelle genome copy number increased in response to nuclear whole genome duplication (WGD), at least partially compensating for altered nuclear genome dosage. Second, transcriptional output of the different cellular compartments is tuned to maintain diploid-like levels of relative expression among interacting genes.
WebCytonuclear coordination between biparental nuclear genomes and uniparental cytoplasmic organellar genomes in plants is often resolved by genetic and transcriptional cytonuclear responses.
