Seedling coleoptile growth. Measurement of the coleoptile length of etiolated rice seedlings grown in air (A) and ethylene (B). The coleoptile phenotype of light-grown ZH11 and 35S:OsRTH1 (line L6) seedlings in air and ethylene, viewed from the side (C) and back (D). (E) Chlorophyll content of coleoptiles of light-grown ZH11 and 35S:OsRTH1 line L6. Numbers in (C), (D), and on the x-axis (E) indicate the ethylene concentration (μl l−1). Data are the mean ±SD for (A) and (B), n ≥ 15, and mean ± SE for (E) of 3–5 measurements. **Significant difference (Fisher’s LSD, α=0.01) between 1-MCP-treated ZH11 and air-grown ZH11 and transformation rice lines (A), or ethylene-treated ZH11 and transformation rice lines (B). a (chlorophyll a) and b (chlorophyll b) indicate identical chlorophyll contents between ZH11 treated with 10 μl l−1 and 100 μl l−1 ethylene (Student’s t-test, P > 0.05).
