Table I. Biomass measurements of ccr1 ProSNBE:CCR1 lines.
Measurements were performed on fully senesced plants. For the stem measurements, the leaves, siliques, and seeds were removed. The data represent average values ± sd and the number of repeats are indicated by asterisks: *, 20 repeats for the wild type and the ccr1 ProSNBE:CCR1 lines and 40 repeats for the ccr1 mutants; **, 12 repeats for the wild type and the ccr1 ProSNBE:CCR1 lines and 24 repeats for the ccr1 mutants; and ***, six repeats for the wild type and the ccr1 ProSNBE:CCR1 lines and 12 repeats for the ccr1 mutants. Note that the set containing ccr1-3, ccr1-3 ProSNBE:CCR1, and wild-type plants and the set containing ccr1-6, ccr1-6 ProSNBE:CCR1, and wild-type plants were grown in two independent experiments. Different letters represent significant differences at the 0.05 significance level (Dunnett-Hsu adjusted Student’s t test). Total plant biomass = biomass of the aerial part of the plant, just above the rosette.
