Chromosomal polymorphism of Calendula officinalis revealed by molecular cytogenetic markers
Journal: Turczaninowia

In karyotypes of Calendula officinalis L. (Asteraceae) (2n = 32) from various ecological and geographical places of growth, intraspecific polymorphism was studied based on patterns of chromosomal localization of molecular cytogenetic markers: C/DAPI bands and also 45S and 5S rDNA clusters. In all calendula samples, variable C/DAPI bands were found in the proximal-median regions of chromosomes. FISH revealed similar localization on chromosomes of the main 45S and 5S rDNA clusters: 45S rDNA cluste
