Cryptochrome Light Signals Inhibit Auxin Responses.

Protonemal inocula were cultured for 10 days under different light conditions in the presence of 0.1 to 100 μM NAA in the medium.

(A) Representative colony images of cryptochrome disruptants grown on medium containing different concentrations of NAA. Data obtained from the addition of 0.1 and 10 μM NAA are shown. The colonies incubated under the same light conditions without NAA are shown in Figure 4. Bar = 2 mm for all panels.

(B) The ratio of caulonemal cells to chloronemal cells in 100 protonemal subapical cells incubated under different light conditions in the presence of NAA. Subapical cells of the protonemata were classified into chloronemal cells and caulonemal cells. The mean ±se of the number of caulonemal cells obtained from eight independent colonies, and 100 protonemal cells in each colony, were classified.
