Histochemical GUS Staining Patterns of DR5::uidA and CYCB1;1::uidA in Transfer Experiments from NPA to NAA, from NPA to MS Medium, and from MS Medium to NAA.

(A) DR5::uidA on NPA. The arrow indicates the root apical meristem.

(B) DR5::uidA after transfer from NPA to NAA for 1.5 h.

(C) DR5::uidA after transfer from NPA to NAA for 3 h.

(D) DR5::uidA after transfer from NPA to MS medium for 6 h.

(E) DR5::uidA after transfer from NPA to MS medium for 6 h (detailed image).

(F) CYCB1;1::uidA after transfer from NPA to MS medium for 6 h.

(G) CYCB1;1::uidA after transfer from NPA to MS medium for 10 h. The arrow indicates the first lateral root initiation site at the apical end of the root.

(H) CYCB1;1::uidA after transfer from MS medium to NAA for 4 h. Arrows indicate the first initiation sites in the basal half of the root.

(I) CYCB1;1::uidA after transfer from MS medium to NAA for 6 h. The lateral root initiation sites are along the entire length of the root. Arrows indicate developing lateral root primordia.

(J) CYCB1;1::uidA after transfer from MS medium to NAA for 8 h. The entire pericycle is activated.
