Bold indicates a statistically significant difference compared to WT, and asterisk indicates a statistically significant difference compared to OE-FLA11; P < 0.05 using Student's t-test.

Growth stages as outlined in Boyes et al (2001).

Transgenic plants with 1TC were used. Data are shown as mean ± Sd. N = 9 plants from 3 independent transformed lines.
