Fig. 2: Expression analysis by RT-qPCR of phenylpropanoid biosynthesis genes in Fuji and Royal Gala apple tissues subjected to sudden sun exposure.

From: Photooxidative stress activates a complex multigenic response integrating the phenylpropanoid pathway and ethylene, leading to lignin accumulation in apple (Malus domestica Borkh.) fruit

Fig. 2

Non-Exp: nonexposed fruit, Exp: exposed fruit without sun damage, and Sev: exposed fruit with severe sun damage. Transcript levels of MdPAL, MdCHS, MdF3H, MdCOMT1, and MdCAD were analyzed after different times of sun exposure in the skin (a, c, e, g, i, respectively) and flesh (b, d, f, h, j, respectively) of Fuji apples and in the skin (k, m, o, q, s, respectively) and flesh (l, n, p, r, t, respectively) of Royal Gala apples. Data correspond to the mean ± SE of three biological replicates. Different letters indicate significant differences (P < 0.05; two-way ANOVA)
