  • See Methods for design and statistical analysis. Transformed values used for statistical analysis are given in brackets. Superscript letters indicate significant difference (P < 0.01) from the wild type. Genotypes marked with different letters are significantly different from each other. Elongated vegetative internodes (V.I.) below the first flower were counted.
