Contributions to cytogenetics of Plectranthus barbatus Andr. (Lamiaceae): a medicinal plant
Accessions of Plectranthusbarbatus (Lamiaceae), a medicinal plant, were investigated using a cytogenetic approach and flow cytometry (FCM). Here, we describe for the first time details of the karyotype including chromosome morphology, physical mapping of GC rich bands (CMA3 banding), as well as the mapping of 45S and 5S rDNA sites. All accessions studied showed karyotypes with 2n = 30 small met...
