Figure 3.

rwa mutants exhibited shoot and root growth deficiency. Shoot growth was measured for 6-week-old triple mutants along with the wild type and rwa2 rwa4 double mutant, the only double mutant with reduced growth. A and B, Diameter of leaf rosette. C, Length of inflorescence stem. A, Short day. B and C, Long day. D, The root growth of the same genotype was measured between 2 and 7 d after germination (n = 10–25). Asterisks indicate significant difference from the wild type (Student’s t test, P < 0.05). Error bars indicate se (n = 4–19).
