From: Down-regulation of POLYGALACTURONASE1 alters firmness, tensile strength and water loss in apple (Malus x domestica) fruit

Figure 4

Transpirational water loss in transgenic PG1as and ‘Royal Gala’ control fruit. Fruit were initially ripened at 5°C for 16 weeks then transferred to 20°C for 9 weeks. A) Representative photograph of PG1as-41, PG1as-275 and ‘Royal Gala’ (RG) control fruit after being held for 9 weeks at 20°C. Note how the PG1as-41 and PG1as-275 fruit were substantially less wrinkled than the control. B) Weight loss (representing mainly water loss) was measured every 1–2 weeks for the 9 weeks fruit were held at 20°C. Weight loss is presented as a percentage of starting weight after transfer to 20°C (n = 4–6 ± Standard Error and T-test statistics between apples containing the transgene and untransformed controls are shown).
