Cold stress triggers premature fruit abscission through ABA-dependent signal transduction in early developing apple
Fig 3
Spatial expression patterns of target genes involved in hormone metabolism and stress response in cold-stressed apple subunit consisting of fruit, branch, and pedicel.
(a) abscisic acid (ABA) hormone biosynthesis, catabolism, and signal transduction; (b) Cold stress; (c) Drought stress; (d) Abscission-zone (AZ) formation; (e) Ethylene; (f) Auxin; (g) Gibberellin. MDP0000336547 was used as reference gene. Data are mean ± standard error (6 ≤ n ≤ 8). * indicate significant difference in relative expression between cold treatment and control at p < 0.05 by Student’s t-test.
