Cold stress triggers premature fruit abscission through ABA-dependent signal transduction in early developing apple
Fig 4
Spatial expression patterns of genes involved in metabolic responses.
(a) Cold response, (b) abscisic acid (ABA) transport, (c) ethylene biosynthesis, and (d) cell wall modification in apple subunits consisting of a branch, pedicel, and fruit. Samples were grouped by treatments as follows: Control (water); ABA (125 mg/L of ABA); Cold (initial cold shock at 4 °C for 2 hr); Cold + ABA (125 mg/L ABA followed by initial cold shock at 4 °C for 2 hr). MDP0000336547 was used as reference gene. Data are mean ± standard error (n = 6). Data were analyzed using two-way ANOVA. Values with different letters differ significantly from each other at p < 0.05.
