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.
