Figure 3

Gravitropic responses of wildtype (Col), tac1, lazy1, and tac1;lazy1 Arabidopsis plants after a 90-degree reorientation. (A) Images of the same representative Col, tac1, lazy1, and tac1;lazy1 plants at 30-minute, 6-hour, and 12-hour time points. (B) The rate of bending in response to reorientation represented by the decreasing area of circles that best fit the curve of each inflorescence meristem bend between 1.5 and 12 hours after reorientation. Each data point represents the average area from four independent experiments, each with five to nine plants per genotypes. Student’s t-test results found significant differences between the Col and lazy1 and Col and tac1;lazy1 values at every time point (p < 0.05). No significant differences were found between Col and tac1 or lazy1 and tac1;lazy1 at any time point. Data points were fit with a power trendline and error bars indicate SEM.
