Cytonuclear disruption may accompany allopolyploid evolution as a consequence of the merger different nuclear genomes in cellular environment having only one set progenitor organellar genomes. One path to reconcile potential cytonuclear mismatch is biased expression for maternal gene duplicates (homoeologs) encoding proteins that target plastids and/or mitochondria. Assessment this transcriptional form coevolution at level individual cells or cell types remains unexplored. Using single-cell (sc-) and single-nucleus (sn-) RNAseq data from eight tissues three species, we characterized type–specific variations coevolutionary homoeologous demonstrated temporal dynamics patterns across development stages during cotton fiber development. Our results provide unique insights into plant allopolyploids level.
