FIGURE 4

INV activities, sugar contents and starch accumulation in leaves of wild-type (WT) and the MeCWINV3-overexpressed (OE) cassava plants. (A–C) Contents of glucose (A), fructose (B), and sucrose (C) under a day/night cycle. (D) Relative transcription level of MeCWINV3. (E–G) The enzymatic activity assay of CWINV (E), VINV (F), and CINV (G). (H,I) Iodine staining of leaves collected at 6:00 a.m. (H) and their total starch contents (I). Different letters indicate significant differences (one-way ANOVA, p < 0.05).
