rack1b-2 and rack1c-1 mutations enhance the rosette leaf phenotype of rack1a mutants. (A) The phenotype of rack1 mutants. Shown are plants grown for 48 days under 10/14 h photoperiod. Scale bars, 2 cm. (B) The number of rosette leaves of rack1 mutants. (C) The rate of rosette leaf production of rack1 mutants. The rate of rosette leaf production is expressed as the number of rosette leaves divided by the age of plants. (D) The size of rosette of rack1 mutants. The number of rosette leaves, the rate of rosette leaf production and the size of rosette were measured from plants grown for 48 d under 10/14 h photoperiod. Shown in (B) to (D) are the averages of at least four plants ± S.E. The same experiment was repeated twice with similar trends and the data from one experiment were presented. *, significant difference from Col, P < 0.05. #, significant difference from rack1a single mutant, P < 0,05. **, significant difference from rack1a-1 rack1b-2 double mutant, P < 0.05.
