Somatic chromosomes of Capsicum chinense: A-B, fluorescent chromosome banding with CMA/DA/DAPI; A, CMA/DA fluorescence (yellow); B, DA/DAPI fluorescence (blue). Arrows indicate CMA + /DAPI − NOR heterochromatin. C-D, fluorescent in situ hybridization with 18S (green) and 5S (red) rDNA probe. Arrows indicate 18S and 5S rDNA. Homologous chromosomes are indicated with the same number.-Scale bar = 10 µm.
