Specific staining of human chromosomes in Chinese hamster x man hybrid cell lines demonstrates interphase chromosome territories [PDF]

open access: yes, 1985
In spite of Carl Rabl's (1885) and Theodor Boveri's (1909) early hypothesis that chromosomes occupy discrete territories or domains within the interphase nucleus, evidence in favor pf this hypothesis has been limited and indirect so far in higher plants ...

Cytogenetic studies in the genus Pentaschistis (Poaceae: Arundinoideae)

open access: yesBothalia: African Biodiversity & Conservation, 1998
Cytogenetic studies of 45 specimens, representing 16 taxa of the genus Pentaschistis (Nees) Spach confirmed two basic chromosome numbers (x = 7, 13) for the genus. Chromosome numbers for five species and one subspecies are described for the first time, i.

Genetic control of isozymes in the primary gene pool Phaseolus lunatus L. [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 1999
Suitable electrophoretic separation methods of 34 isozymes from 17 enzyme systems resolved in Phaseolus lunatus L. (Lima bean) were developed. Data from the migration of the staining zones indicated that three loci control EST, GPI, IDH and MDH ...
