Jing JW, Davis TM, Zhang Q. Perspectives on Elevated Ploidy in Regenerants from Plant Tissue Culture and Transformation. Research & Reviews: Journal of Botanical Sciences. 2016;5 (4) :19-21.
Elevated ploidy is a common phenomenon among plants regenerated
from tissue culture. Contributors to this effect include cells of elevated ploidy
present within normally diploid or polyploidy explant tissues, endoreduplication
by individual cultured cells, and effects of
environmental factors on cell
division. Because polyploidization can result in morphological changes and thus,
different adaptabilities, the determination of ploidy in transgenic regenerants
plants is recommended when evaluating phenotypes and conducting mutant
screens subsequent to genetic transformation.
