(B) VIGS-Del/Ros1 silenced sectors had reduced
hydrophilic antioxidant capacity compared to
purple sectors. Error bars show the SEM (n = 3).
S, silenced sectors; NS, nonsilenced sectors.
*p < 0.05 and **p < 0.01 compared to the WT.
(C and D) Quantitative RT-PCR analysis of genes
encoding cell-wall-modifying enzymes in WT and
Del/Ros1 fruits during ripening. Polygalacturonase
2a (SlPG2a) (C) and b-galactosidase 4 (SlTBG4) (D)
are shown. Error bars show the SEM (n = 3).
(E and F) Total polygalacturonase (E) and b-galac-
tosidase (F) activities in red and purple fruit at
different stages during ripening. Error bars show
the SEM (n = 3). *p < 0.05 and **p < 0.01 compared
to the WT at the same stage.
