Karyotype analysis ofAstragalus effususBunge (Fabaceae)

Karyotype analyses of ten sections of Trigonella (Fabaceae)

Karyotypes of ten sections of genus Trigonella Linnaeus, 1753 (Fabaceae) from Turkey were investigated. Somatic chromosome numbers of examined species were determined as 2n=14 and 16. The karyotype analyses of the species were carried out and somatic chromosome numbers of Trigonella plicata Boiss., 1872, Trigonella brachycarpa (Fisch.) Moris, 1833, Trigonella rostrata Boiss., 1872, Trigonella l...

Karyotype Analyses of Four Astragalus L. (fabaceae) Species from Turkey

Astragalus L. is a perennial herbaceous genus belonging to the family Fabaceae. Chromosome morphology was defined for the first time in four species of Astragalus namely; A. antalyensis A.Duran & Podlech, A. nezaketae A.Duran & Aytaç, A. cariensis Boiss. & A. schizopterus Boiss. All species contained diploid chromosome numbers of 2n = 16. However, polyploid cells (4x = 32) were also observed in...

Karyotype analysis of Rheum palmatum.

Rheum palmatum, one of the source plants of the traditional Chinese medicine rhubarb, is anendemic and endangered species. To our knowledge, this is the first report on the chromosome number and karyotype of this species. Sectioning combined with micrography was used to analyze the karyotype. The following results were obtained: R. palmatum had a stable chromosome number 2n = 22; the basic numb...

Karyotype Analysis and Chromosome Banding

Nearly all methods of chromosome banding rely on harvesting chromosomes in mitosis. This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
