Expression of 35S:OsCTR2 1–513 confers a constitutive ethylene response in rice. (A–E) qRT-PCR analysis of OsCTR2 mRNA level (A), seedling phenotype (B), primary root length (C), adventitious root number (D), and seedling leaf length (E) of the wild type (ZH11) and 35S:OsCTR2 1–513 transgenic lines. (F–I) Leaf senescence phenotype (F), relative chlorophyll a content (G), coleoptile phenotype (H), and coleoptile length (I) of the wild type (ZH11) and transgenic lines. (J) Coleoptile phenotype of light-grown seedlings. (K) Ethylene evolution in the wild-type (ZH11) and transgenic lines. Data are means ±SD of three independent experiments performed in triplicate. L, transformation line. (This figure is available in colour at JXB online.)
