Gravitropic reorientation after transient induction of gai-1D. Col and HS::gai-1D seedlings were grown for 3 d in darkness and subject to a 30-min heat shock at 37°C before turning the plates 90°. Reorientation of the hypocotyls was monitored in darkness as explained in “Materials and Methods.” When used, PAC concentration was 0.4 μm. Error bars represent sd (n > 16 individual seedlings). The effect of PAC and HS::gai-1D with respect to the wild type was statistically significant (P < 0.05) as indicated by a two-way ANOVA test. [See online article for color version of this figure.]
