Figure 1.

dwf1-1 displays dwarfed plant form and cellulose deficit. A, Wild-type (WT) and dwf1-1 plants grown in natural light conditions for 2 weeks in the greenhouse (24°C). Bar = 5 cm. B, The fully expanded mature wild type and dwf1-1. Bar = 25 cm. C, Height measurement between dwf1-1 and the wild type evaluated at maturity (n = 100). D, Cellulose content was measured as a proportion of AIR and determined on leaves and stems of dwf1-1 and the wild type (n = 4; error bars indicate sem). Asterisks indicate significance by Student’s t test. **, P = 0.01; ***, P = 0.001.
