A karyotypic analysis of three species of Skimmia (Rutaceae) in East Asia was performed that examined 88 individuals from 53 localities. Chromosome numbers of S. japonica, S. reevesiana and S. arisanensis were 2n=30, 31, 32 (=30+0−2B), 2n=60 and 2n=60, respectively. The chromosome number of S. arisanensis was reported for the first time. All species had a large chromosome pair or quartet (the first pair or quartet) with a median–submedian centromere in the karyotype. In S. japonica the arm… 
Pollen morphology of the genus Skimmia (Rutaceae) and its taxonomic implications
TLDR
Pollen morphology of the genus Skimmia was studied and it was found that pollen dimorphism is suggested in the aperture number in accordance with the floral system.

Molecular and cytological evidences denied the immediate-hybrid hypothesis for Saxifraga yuparensis (sect. Bronchiales, Saxifragaceae) endemic to Mt. Yubari in Hokkaido, northern Japan
TLDR
The results indicate that S. yuparensis is not an immediate hybrid of S. rebunshirensis and S. nishidae but a distinct lineage and an extremely narrow endemic species, that deserves for intensive conservation.
Hybridization, coexistence, and possible reproductive interference between native Oxalis corniculata and alien O. dillenii in Japan
TLDR
The putative hybrid is virtually sterile, indicating that hybridization led to a waste of gametes and may result in reproductive interference between the two parental species.
Pollen Morphology of Rutaceae from Brazilian Forest Fragments
TLDR
Pollen morphology of 12 native Brazilian species of Rutaceae from forest fragments of São Paulo, Brazil is presented to expand the morphological knowledge of the species, thus contributing to taxonomic knowledge and conservation of species and the forest area.

Correlation between distyly and ploidy level in Damnacanthus (Rubiaceae).
TLDR
Based on the present chromosome number study, the taxonomy of the varieties of D. indicus should be revised and a strong correlation exists between chromosome number and occurrence of distyly.
Cytogenetics of Rutaceae IV
TLDR
The tribe Aurantieae is the only one to be characterized by a single nuclear type (areticulate) whereas the remaining tribes show varied nuclear structure for the different subtribes, and some tribes appear to have a characteristic nuclear type for each subtribe.
Chromosome counts in the genus Skimmia (Rutaceae)
TLDR
This account gives the chromosome numbers for all four species in the genus Skimmia Thunb, and all but one of the subspecies (S. arborescens subsp. nitida) as defined in this new classification.
Cytology of Rutaceae and Simarubaceae
1. Chromosome numbers have been determined for the first time for 10 species belonging to 8 genera of the two families, Rutaceae and Simarubaceae.2. The process of meiosis has been studied in detail
Genetic improvement of Egyptian henbane, Hyoscyamus muticus L. through induced tetraploidy

TLDR
The overall improvement in the colchiploids has the advantage of enhancing nearly 1.5 times the production potential of the economic product — the total alkaloids.
Ploidy Effects in Isogenic Populations of Alfalfa : III. Chloroplast Thylakoid-Bound Coupling Factor 1 in Protoplasts and Leaves.
TLDR
Cellular content of CF1 increases proportionately with the amount of DNA per cell or gene dosage in alfalfa, as well as across ploidy levels of both isogenic sets.
Cytogenetics of Rutaceae. III. Heterochromatin Patterns
TLDR
The results show a wide diversity of patterns in the Rutaceae family although there is a tendency to maintain the same pattern for each analysed genus.
Ploidy Effects in Isogenic Populations of Alfalfa : II. Photosynthesis, Chloroplast Number, Ribulose-1,5-Bisphosphate Carboxylase, Chlorophyll, and DNA in Protoplasts.
TLDR
It was concluded that increased cell volume rather than increased cell number per leaf is responsible for the increase in leaf size with ploidy.
Sex Determination by Sex Chromosomes in Dioecious Plants
TLDR
Dioecious plants have unisexual flowers, which have stamens or pistils, which are caused by the suppression of opposite sex primordia, and sex chromosome linkage in these plants suggests that female suppressor and stamen promoter genes are localized on the Y chromosome.

TLDR
Detailed chromosome counts have been made in 61 species, belonging to 33 genera of Rutaceae, and the base number x = 10 is proposed for the genus Rutaceae on the basis of the present results.
