Hypocotyl Elongation of Cytokinin Receptor Mutants Shows No Altered Red Light Sensitivity.
(A) Hypocotyl elongation in the light and in the dark 7 DAG. Error bars represent se (n = 15).
(B) Hypocotyl elongation of Arabidopsis plants grown in continuous red light (R; 660 nm/3.4 μE, 4 DAG) or far-red light (FR; 724 nm/3.4 μE, 4 DAG). Error bars represent se (n > 30).
(C) Reduction of hypocotyl elongation in red light or far-red light shown in (B) compared with the elongation in the dark.
The ahk2-5 ahk3-7 cre1-2 triple mutant was used in all assays.
