FISH-aimed karyotype analysis in Aconitum subgen : aconitum reveals excessive rDNA sites in tetraploid taxa [PDF]

open access: yes, 2018
The location of 5S and 35S rDNA sequences in chromosomes of four Aconitum subsp. Aconitum species was analyzed after fluorescence in situ hybridization (FISH). Both in diploids (2n = 2x = 16; Aconitum variegatum, A. degenii) and tetraploids (2n = 4× = 32;
