Analysis of Nuclear DNA content in plant cells by Flow cytometry

  • Published:
Biologia Plantarum


Flow cytometry was used to analyse the DNA content of nuclei isolated from intact plant tissues and from callus and cell suspension cultures invitro. Cell nuclei were isolated either mechanically (chopping, syringing) or by a hypotonic lysis of isolated protoplasts. Although both methods gave similar results, a slight shift to lower ploidy levels was observed after protoplast isolation from intact tissues and calli. No differences were observed if the two methods were compared using cell suspension cultures. The results showed that flow cytometry is a rapid method of nuclear DNA content analysis in intact plant tissues and variousin vitro cultures.
