On the hybrid origin of Narcissus biflorus (Amaryllidaceae): analysis of C-banding and rDNA structure
Get PDFAbstract Giemsa and fluorochrome banding with DAPI and chromomycin A3, were utilized to assess karyological details which correlate N. biflorus with the parental species: N. tazetta and N. poeticus. The banding profile in N. biflorus clearly reproduced the model of its progenitors. The EcoR1 restriction pattern of rDNA obtained by Southern blot hybridization indicated, in our material, that each species has more than one ribosomal gene type and in N. biflorus both the ribosomal repeat units of the progenitor species are present
