Data were collected from the wild type, WOX11 overexpression (OW1, OW2, and OW7), and RNAi transgenic positive (RW4, RW10, and RW18) and negative segregants (RW− and OW−) in the T1 generation lines. Data represent the means ± se of plants in each line. Significant differences are indicated at the 5% (*) and 1% (**) probability levels (Dunnett's two-tailed tests).
