The dcl1-13 mutation suppresses the hyl1 phenotype in a semidominant manner. (A) Rosette images of wild-type (WT) plants, hyl1-2 plants, and heterozygous and homozygous hyl1 suppressors (hyl1-2 dcl1-13/DCL1, and hyl1-2 dcl1-13/dcl1-13, respectively). Bar = 1 cm. (B) Successive rosette leaves and their numbers (average ± SD) from the plants shown in A. n = 17–21. Bar = 1 cm. Values designated by the same superscript letter are not significantly different at the P = 0.01 level in the t-test. (C) Degrees at leaf bases (indicated in illustration) of the third and fourth rosette leaves of plants shown in A. n = 17–20. Bars indicate SD. Values are significantly different between each possible comparison at the P = 0.01 level in the t-test.
