Fig. 4. Defective development of the quadruple phyA phyB cry1 cry2 mutant of Arabidopsis thaliana. (A) The wild type and the quadruple mutant 3 weeks after sowing. (B) The quadruple mutant 10 weeks after sowing. A 4-week-old wild type is displayed to illustrate the divergent morphology because 10 weeks after sowing the wild type had completed the cycle and fully senesced. (C) Defective development of early siliques (arrow) in the quadruple mutant. A normal wild type silique is shown for comparison.
