Figure 3. Statistical measurement of mesocotyl length in Zheng58 wild-type plants and elm2 mutant plants.

Zheng58 wild-type seedlings and mutant elm2 seedlings were grown for 7 d in continuous darkness, white light, red light, far-red light, or blue light conditions. The sample size was 16-18 seedlings per treatment/genotype. Asterisk indicates significant difference as compared with Zheng58 wild-type at P<0.01 (Student’s t test).
