Other claims from this paper (12)
- Observation Daustinia montana has 2n = 16 chromosomes.
- Observation Jacquemontia mucronifera and J. pentanthos have 2n = 36 chromosomes.
- Observation Daustinia montana has a genome size of 1C = 0.90 pg.
- Observation Jacquemontia mucronifera has a genome size of 1C = 2.32 pg.
- Observation Probabilistic analyses support a basic chromosome number of x = 14 for Convolvulaceae and Dicranostyloideae.
- Mechanism Dysploidy and polyploidy have shaped karyotype evolution within Jacquemontia.
- Mechanism Dysploidy underlies the major karyotype differences between the two genera.
- Observation Novel CMA/DAPI banding patterns were characterized for Daustinia montana.
- Observation Novel CMA/DAPI banding patterns were characterized for five Jacquemontia species.
- Observation All species of Convolvulaceae studied exhibited terminal CMA+ bands.
- Observation DAPI + heterochromatin was exclusive to Jacquemontia.
- Observation Karyotypic affinities among Daustinia, Jacquemontia and Dinetus provide new cytological evidence on the phylogenetic position of Daustinia montana.
