Table 1.

Ethylene levels (nmol g^–1 FW h^–1) measured in Arabidopsis seedlings of the wild-type (WT) and lines overexpressing (35S:Pgb1) or down-regulating (Pgb1-RNAi) AtPgb1 cultured for 24 h in 40% PEG (–1.76 MPa). Values are means ±SE of three biological replicates. Different letters indicate statistically significant differences (P<0.05)
