Fig. 3: SlMYB33-RNAi results in delayed flowering in tomato.

a Expression analyses of SlMYB33 and SlGAMYB1 in the flower buds (5-mm length) of WT plants and SlMYB33-RNAi lines by qRT-PCR. Each value is the mean ± SD of three biological replicates. b Wild-type (WT) plants and progenies of SlMYB33-RNAi lines. All genotypes were sown at the same time and grown under the same environmental conditions. When the flowers of the WT plants open, the RNAi lines are in the vegetative stage. Bar = 5 cm. c Numbers of leaves at first flowering in WT and the progenies of SlMYB33-RNAi lines. Each value is the mean ± SD of three biological replicates, and six plants were examined for each replicate. d Days to anthesis in WT and the progenies of SlMYB33-RNAi lines. Each value is the mean ± SD of three biological replicates, and six plants were examined for each replicate. Asterisks indicate significant differences between the RNAi lines and WT by Student’s t tests (*P < 0.05; **P < 0.01)
