Colchicine-induced autotetraploidy and altered plant cytogenetic and morpho-physiological traits in Catharanthus roseus (L.) G. Don

open access: yesAdvances in Horticultural Science, 2018
Artificially induced polyploidy is often used to alter plant growth pattern and genetic makeup of certain plant species. This experiment was conducted to induce autotetraploidy in Catharanthus roseus (‘Alba’) which contains diploid chromosomes ...

Chromosome number, genome size and heterochromatin evolution in diploid species of Ipomoea and related genera (Convolvulaceae: Convolvuloideae) [PDF]

open access: yesActa Botânica Brasílica, 2023
Convolvuloideae is a group of plants formed by genera with n = 15 and high stability of chromosome numbers. Despite being stable, polyploidy is the main mechanism of karyotype evolution for the group and seems to be related to speciation events.

Number of nucleoli in diploids and polyploids of the genus Achillea L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
Nucleoli were counted in 9228 interphase nuclei of the apical root meristem of 40 Achillea L. taxa (di-, tetra-. hexa- and octoploids). It was established that the distribution of nucleoli number in an interphase nucleus can be used as a rough practical ...
