Other claims from this paper (3)
- Observation The genome sizes of the two Cuscuta species differ significantly.
- Observation The two Cuscuta species have allopolyploidy via independent hybridization involving different ancient parents.
- Mechanism Genomic rearrangements (gene gain and loss, homoeologous recombination, transposable element dynamics) have likely contributed to the genomic diversity of the Cuscuta lineages.
