Analysis of nuclear DNA content and ploidy in higher plants.
This is the first of a series of units discussing the application of cytometry to plant material. Techniques commonly used for mammalian nuclei evaluation need considerable modification to be successful with plant material. David Galbraith and his colleagues bring together many years of knowledge in plant cytometry. Their unit provides detailed protocols on measuring DNA content, ploidy, and ce...
متن کاملNUCL EAR DNA CONTENT AND DNA PLOIDY ANALYSIS IN BREAST CANCER
To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...
متن کاملDetermining Ploidy Level and Nuclear DNA Content in Rubus by Flow Cytometry
Nuclear DNA flow cytometry was used to differentiate ploidy level and determine nuclear DNA content in Rubus. Nuclei suspensions were prepared from leaf discs of young leaves following published protocols with modifications. DNA was stained with propidium iodide. Measurement of fluorescence of 40 genotypes, whose published ploidy ranged from diploid to dodecaploid, indicated that fluorescence i...
متن کاملDNA content measurement for DNA ploidy and cell cycle analysis.
This unit presents the most common methods of DNA content analysis. The techniques differ primarily in the mode of cell permeabilization (detergents versus prefixation with alcohol) and composition of the stain solution. Protocols are given for analysis of fixed cells, tissue samples, live cells (for subsequent sorting and culture), archival paraffin-embedded tissue, and apoptotic cells.
متن کاملIntraspecific DNA content variability in Festuca pallens on different geographical scales and ploidy levels.
BACKGROUND AND AIMS Intraspecific genome size variability of Festuca pallens occurring on relict rocky steppes in Central Europe was studied on two ploidy levels and three geographical scales: (1) local scale of 24 populations, (2) landscape scale of three transects in river canyons or hill systems, and (3) global scale of 160 samples covering the whole distribution area. METHODS DAPI flow cy...
