Morphological Changes in the Stems of the Activation-Tagged Mutant, PtaLBD1-oe, and PtaLBD1-SRDX Plants.

(A) Stem diameter at the base (first internodes above shoot/root junction).

(B) Internode length between 3rd and 8th node.

(C) Number of internodes measured in 2-month-old plants.

White bars represent WT-717, gray bars represent mutant, black bars represent PtaLBD1-oe, and gradient bars represent PtaLBD1-SRDX plants. Measurements were taken from ~2-month-old plants; values are reported as means ± se (n = 5). Asterisks indicate significant differences relative to WT-717 plants as determined by Student’s t test, with ** and * denoting P < 0.01 and P < 0.05, respectively.
