Figure 2. Tissue-specificity and ethylene responsiveness of the accumulation of the 36 kDa ACO antigen and of Ps-ACO1 mRNA in the embryonic axes of pea seeds.
The embryonic axes were dissected from pea seeds imbibed for 48 h followed subsequently by 8 h of treatment with 30 mL L-1 ethylene. Comparison of the ethylene-induction of Ps-ACO1 in (a) shoot (S) and root (R) tissues and (b) the root tip (rt; 0–2.5 mm), cell elongation zone (ez; 2.5–6 mm), and cell differentiation zone (dz; > 6 mm) of the radicle. Immunoblot and RNA blot analyses were as described in Fig. 1.
