Abstract
Karyotype analysis and chromosomal locailization of 45S and 5S rDNAs using McFISH (multi-color fluorescence in situ hybridization) were carried out in Jeffersonia dubia Benth., which is one of medicinal plants belonging to Berberidaceae. The somatic metaphase chromosome number was 2n=2x=12 and the size of chromosomes ranged 1.95~3.50 ㎛. The chromosome complement consisted of two pairs of metacentrics (chromosomes 1 and 3), two pairs of submetacentrics (chromosomes 2 and 4) and two pairs of subtelocentrics (chromosomes 5 and 6). In McFISH, one pair of 45S rDNA site was detected on the centromeric region of chromosome 2 and three pairs of 5S rDNA sites were detected on the short arm of chromosome 4,5 and 6, respectively.
