Fig. 1

The content of IAA and expression pattern of MdPINs in the adventitious roots of apple self-rooted stocks. (a) The superior shallow-rooted and self-rooted apple stock: 13–13. (b) The superior shallow-rooted and self-rooted apple stock: 13–10. (c) The superior deep-rooted and self-rooted apple stock: 13–22. (d) The superior deep-rooted and self-rooted apple stock: 12–2. (e) The content of the endogenous hormone IAA in the adventitious roots of self-rooted apple stocks. (f) Transcript levels of MdPIN3 and MdPIN10 in the adventitious roots of self-rooted apple stocks. Scale bars = 2 cm. Error bars indicate ± SD (n = 3, from three technical replicates). Values in Fig. 1 were derived from experiments that were performed at least three times with similar results, and representative data from one replicate are shown
