Abstract

Nuclei from Mesembryanthemum crystallinum (ice plant) exhibit multiple levels of ploidy in every tissue as revealed by flow microfluorometric analysis of isolated nuclei stained with mithramycin. Multiples of the haploid nuclear genome complement (1C) corresponding to 2C, 4C, 8C, 16C, 32C, and 64C were observed. The distribution of nuclei among the different ploidy levels is tissue-specific and in leaves is characteristic of the stage of development. This type of genome organization has been identified in eight other succulent CAM (crassulacean acid metabolism) plant species with small genomes. Multiploidy may be a common property of this type of plant.
