Verbatim
e0“All four species exhibit exclusively metacentric chromosomes, with M. trifoliata and N. peltata being hexaploid (2n = 54), N. coreana tetraploid (2n = 36), and N. indica diploid (2n = 18).”

Other claims from this paper (12)
- Observation All four Menyanthaceae species had metacentric chromosomes.
- Observation N. peltata was hexaploid, with 2n = 54.
- Observation N. coreana was tetraploid, with 2n = 36.
- Observation N. indica was diploid, with 2n = 18.
- Observation Species had one to four 45S rDNA loci.
- Observation Species had one to three 5S rDNA loci.
- Association rDNA site number did not correlate directly with ploidy.
- Observation The karyotypes suggest a conserved base chromosome number of x = 9.
- Observation The species have largely symmetrical karyotypes.
- Observation M. trifoliata has fewer rDNA loci than expected for a hexaploid.
- Mechanism The low rDNA locus number in M. trifoliata indicates rearrangements and locus loss through diploidization.
- Observation M. trifoliata has an evolutionarily stable genome structure despite polyploidy.
