Floral organ abscission is delayed in plants with AtDOF4.7 overexpression. Flowers of 5-week-old plants were analyzed and compared. A, Flowers along the inflorescence in the wild type (WT) and AtDOF4.7 overexpression lines (S107 and S109). B, Flower organs were still attached to the dry siliques in S107 and S109. C, Petal breakstrength, which is the force required to peel the petals from the flowers, was measured from positions 2 to 30. Error bars indicate sd from measurements for 17 wild-type, S107, and S109 plants each, with a minimum of 15 measurements at each position. [See online article for color version of this figure.]
