Effect of seed removal and hormone treatment on the relative transcript abundance of the ethylene receptor genes PsERS1 (A, B, C) and PsETR2 (D, E, F), and the ethylene signaling-related genes PsEBF1 (G, H, I) and PsEBF2 (J, K, L). Two DAA pericarps were split and deseeded (SPNS) and, if STS treated, the deseeded pericarps were immediately treated with STS (1 mM). Twelve hours after splitting and deseeding, pericarps were treated with IAA (50 μM), 4-Cl-IAA (50 μM), or ethephon (1000 mg l^–1) in 0.1% aqueous Tween-80. SPNS and SP controls were treated with 0.1% aqueous Tween-80. Data are means ±SE, n=3–8, with the exception of STS+IAA 2 h treatment, where n=2.
