During the last fifteen years, flow cytometry and sorting greatly contributed to the improvement of our knowledge of plant genome structure and function. This paper reviews the applications of flow cytometry for the analysis of isolated nuclei and chromosomes. Because of its speed, precision and convenience, this method of analysis of the nuclear DNA content finds an enormous number of applications which cover basic research, breeding and production. The results obtained with chromosome analysis and sorting indicate that the technique might greatly simplify the analysis of plant genomes at the molecular level.
