Fig. 4. Effect of msi1 on DNA content in sperm cell nuclei. The DNA content in Arabidopsis sperm cells was estimated relative to the fluorescence intensity after DAPI staining. The relative DAPI fluorescence intensity between control wild-type sperm cells and single sperm-like cells in msi1-1;fas1-1 pollen and in duo1-1 pollen is indicated under the graph. Error bars correspond to standard deviations, and the size of the sample (n) is indicated above each column.
