Figure 5.

Effect of CmF-308 expression in the phloem of tomato plants on root development. Number of lateral roots (A), root dry weight (B), and a picture (C) presenting the differences between roots of transgenic tomato plants expressing CmF-308 under the AtSUC2 promoter (CmF-308-2) as compared with the control variety M-82. (D) Shoot dry weight of transgenic tomato plants expressing CmF-308 under the AtSUC2 promoter (CmF-308-2) as compared with the control variety M-82. Lateral roots were counted in 9-days old seedlings germination on germination papers (A). Shoot and root weight was measured in 3-week old pot-grown plants (B–D). Data represent means of six replications ± SE. Different letters indicate significant differences between the plant lines at p < 0.05 by Student's t-test.
