Figure 5.—

Effect of direct and parental aneuploidy on meristematic traits in an all-Col-0 population. An all-Col-0 trisomic of chromosome 3 was selfed and its progeny divided into aneuploids (A, in open bar) and aneuploidy-parented diploid (Ap2x or Ap2x*; see Figure 4 for details). Each individual was scored for meristematic phenotypes, and the mean trait values of the different subpopulations were compared to each other as well as to a set of 15 control Col-0 plants (WT solid bar) on a pair-wise basis using Student's t-tests. Different letters above two columns indicate significantly different means (P-values < 0.01 to compensate for multiple testing on six independent populations) for these two measurements. Standard errors are indicated.
