Chromosome counts of some Zingiberaceous species from Thailand [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2002 The data on chromosome numbers of 22 species belonging to 10 genera of Zingiberaceae distributed in Thailand were investigated. The somatic numbers range from 20 to 48 showing diploidy and polyploidy.

C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]
, 2006 Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

Circumnutation in the growth of Chara rhizoids
Acta Societatis Botanicorum Poloniae, 2014 The chromosome numbers of 24 species of Achillea L. were determined, among them 4 for the first time (A. chamaemelifolia, A. sulphurea, A. teretifolia, A. vermicularis). A tetraploid form of A. lingulata was found for the first time. The occurrence of di-

Chromosome Segregation Is Biased by Kinetochore Size [PDF]
, 2018 Chromosome missegregation during mitosis or meiosis is a hallmark of cancer and the main cause of prenatal death in humans. The gain or loss of specific chromosomes is thought to be random, with cell viability being essentially determined by selection ...

Problematic octaploid forms and a new chromosome number in the genus Achillea L., 2n = 126
Acta Societatis Botanicorum Poloniae, 2014 Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72).

Cytogenetic study and pollen viability of three populations of Diplotaxis harra (Brassicaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2014 In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of Diplotaxis harra (Forssk.) Boiss. This is the first cytogenetic report of the taxon.
